Jon Trevelyan (UK) If Yorkshire really is ‘God’s Own County’, then clearly the Almighty is an enthusiastic geologist. Just how lucky is the Yorkshire man who, on the same day, can see some of the best and most varied geology in the world, set out in glorious coastal and mountain … Read More
This small, yet informative, booklet takes you on a four-mile walk to 13 sites and through 15 million years of Earth history. The Mortimer Forest Trail is a geology trail in Shropshire that is famous for its outstanding fossils and varied geology. The trail mostly examines Silurian formations such as the Wenlock and Ludlow series.
Bob Williams (UK) In the previous part of this article (see Early Eocene London Clay deposits at High Ongar, Essex (Part 2)), I located the beds exposed at High Ongar in Essex (TQ 556809) within the general, stratigraphic framework of the London Clay. I also argued that examining the habitats in which families of crustacea live today provides clues about the sort of habitats that may have existed when the London Clay in the pits at Aveley in Essex and Ongar (TL 562024) was deposited. In this part, I will continue this comparison using modern lobsters, shrimps and other animals to provide clues about the habitats that may have existed at Ongar and at various other London Clay sites when their fossil relatives were alive. I will also show how one can locate a site like Ongar within the stratigraphic column. Fig. 1. Estimated position of the clay exposures at High Ongar Essex and nearby Aveley, showing the London Clay sedimentary deposits. At this point, it is worth bearing in mind the conditions in which the London Clay deposits are believed to have been laid down. London Clay is not one, uniform deposit. There are a number of sedimentary horizons within the deposit, each horizon reflecting the environment in which it was formed. Broadly, the London Clay is thought to have been laid down in a marine environment influenced by a tropical or subtropical climate. Water depth is thought to have averaged about 200m, but would obviously have varied locally. … Read More
Those of you who have read a few of my book reviews will know that I love geo-guides to small geographical areas, rather than just the big geological scientific issues. In fact, there are lots of good UK guides like this one, to areas such as Dorset and Yorkshire, and many areas of Scotland and Wales, for example. And this is another excellent example of that genre.
Bob Williams (UK) I first encountered the geological deposit known as the “London Clay” when I accompanied a friend to an exposure of the stuff. He told me that it was good for collecting fossils. It was and I was taken aback by the quality and quantity of fossil material. However, I knew nothing at all about the geological details of the sediment. However, like all keen amateurs, I wanted to know more about the deposit. To the uninitiated, the name “London Clay” suggests a single, uniform deposit. However, in truth, it does not fit that description. The name is given to a sedimentary deposit that contains at least five different and distinctive horizons (referred to as Divisions A to E). They were laid down in early Eocene times (50 to 54Ma) in conditions that were particular to slightly different environments or habitats (I use the terms interchangeably in this article). In a non-scientific way, the London Clay environments can be compared to the environments found in an ocean such as the Indian Ocean. Fig. 1. Estimated position of the clay exposures at High Ongar Essex and nearby Aveley, showing the London Clay sedimentary deposits. In broad terms, it is possible to describe the Indian Ocean as having warm, marine waters, being subject to tropical or sub-tropical climates and containing particular life forms. However, a variety of individual habitats can also be found in the Indian Ocean. There are shallow waters, deep waters, coastal waters, reef systems, trench systems, rocky … Read More
Richard M Haw (UK) Blue John is a unique variety of blue-purple banded fluorite. Hydrocarbons or oils have been deposited on some of the crystal surfaces while the mineral was forming. These oil layers are partly responsible for giving the stone an alternate blue and white banding, best seen when the stone is cut in section. It is not known to occur anywhere else in the world and is conﬁned to an area of about 1km³ of the Carboniferous “reef” limestones at Castleton in Derbyshire. Fig. 1. Old picture taken sometime in the 1870s, showing miners digging in the Old Dining Room, now part of the show caves. I have been involved with the public caverns here for a while and I am sure many of you have visited them. However, there are many people who have never even heard of Blue John, so the following article gives a general overview without intending to be too technical. The area Castleton is a small village located in Derbyshire’s “Peak District” between the cities of Manchester and Shefﬁeld. The village is dominated by the ruins of Peveril Castle that was built by the Normans to oversee lead mining in the area. The scenery around Castleton forms a dramatic backdrop and the rolling limestone hills end abruptly atthe vertical face of Mam Tor. Beyond and to the north are the gritstone moors known as the “Dark Peak” that eventually lead up to the two-thousand-foot-high plateau of Kinder Scout. Castleton and the surrounding area … Read More
Jon Trevelyan Britain has a long and proud history of geological museums (and museums that have significant geological collections) dating back at least to early Victorian times. One need only think of William Smith’s revolutionary and magnificent, 1829 Rotunda in Scarborough to understand this (Fig. 1). Fig. 1. The Rotunda, Scarborough. Here, Smith’s fossils were (and are once again, after significant renovation to the building) arranged up a spiral staircase in the order they occur in the rock column – an extremely modern way of doing things. And, of course there is Richard Owen’s Victorian masterpiece, the Natural History Museum in London with, among many other things, its dinosaurs and exhibits of other fossils (Fig. 2). Fig. 2. The Natural History Museum, London. However, the venerable NHM raises an important question. To create a display for the public, to what extent should museums use push-button technology and pretty pictures, rather than displays of the actual subject matter? In recent years, it seems that museums increasingly want to cater merely for children (and certainly not adults), who (apparently) can only be engaged by technology rather than, for example, a well-labelled and beautifully prepared fossil ammonite. The belief seems to be that they simply cannot look at exhibits in the way that Victorians did – with specimens set out in cabinets – but rather, need to be engaged by electronics and graphics that are one remove from the subject matter itself. I suspect that it was this belief that lead the NHM … Read More
This is an interesting little booklet and very much a new departure for the Palaeontological Association. You will be aware that I have reviewed several of its many excellent fossil guides in this magazine. However, this recently published tome is somewhat different.
Ray Chapman (UK) The cliff exposure of the Barton Beds between Highcliffe in Dorset and Barton on Sea in Hampshire are the type section of the Bartonian age and are highly fossiliferous. They are Middle Eocene in age and were deposited between 41.3 and 37Ma. They extend to Southampton in the east, Wareham in the west and Fordingbridge in the north with some other minor exposures in Southeast England. Fig. 1. The Barton Beds viewed from Highcliffe. The beds are marine clays, silts and sands deposited in a generally shallow sea that stretched to the southeast of the present shoreline and across the Hampshire-Dieppe Basin. Terrestrial input was from the west and northwest. The environment was sub-tropical partly because the average global climate was higher than today and partly because Britain was about 100 further south of its current position. The beds are alleged to contain some 600 species of molluscs, marine vertebrates, reptiles and other taxa. Christchurch Bay, between Milford on Sea and Bournemouth, has developed over the last 10,000 years. Previously, the ‘proto-River Solent’ ran eastwards from the rivers Frome, Piddle, Stour, Avon and other small rivers. It ran behind what is now the Isle of Wight along what is now the Solent and joined the large ‘Channel River’ flowing westwards from the Rhine, Rhone and Seine. At the end of the last glacial period, the chalk ridge to the south, which joined what is now the Needles on the Isle of Wight and Handfast Point on Studland, … Read More
Ray Goodwin (UK) It was a hot and sultry summer afternoon in August 1800. A happy crowd was gathered in the small town of Lyme to watch an exhibition of horse jumping in the nearby Rack Field. No one could have guessed that, before the day was out, tragedy would strike from the skies and three women would lie dead beneath a clump of elm trees. With a little 15-month-old baby in her arms, Elizabeth Haskings and two young friends hurried for shelter as, late in the afternoon, the sky darkened and torrential rain began to pour down from the heavens. Minutes later, a brilliant ﬂash of lightning hit the trees and a terrible thunderclap reverberated around the nearby cliffs. As the rain stopped, a horriﬁed crowd walked towards the trees and, amid the charred remains, they saw the outlines of three huddled bodies lying on the ground. The three women were terribly burnt and had been killed instantly. Sheltered by the body of Elizabeth, the baby lay unconscious but, after bathing in water, soon recovered consciousness. Legend has it that she was transformed from being a quiet, ordinary baby into a child of exceptional liveliness and intelligence. Whether this was strictly true or not, we may never know. However, it is a fact that the child, whose name was Mary Anning, was destined to become one of the greatest palaeontologists of the early nineteenth century. Mary Anning was born on 21 May 1799 in the small Dorset town of Lyme. … Read More
Joe Shimmon (UK) With good luck and perseverance, some beautiful fossils can be collected from the London Clay, which outcrops in the south east of England. The phosphatic remains of crustacea, fish and other, rarer vertebrates are well known, and information and images of them are easily accessed, particularly on the Internet site: Sheppey Fossils. (See also Fred Clouter’s article, Sheppeyfossils.com: The genesis of a website, for a review of this website.) However, the formation’s hugely diverse floral assemblage is often overlooked, with little easily accessible information to be found on the web. Therefore, in this short article, I aim to introduce the most interesting of the London Clay’s plant fossils – its fossil seeds. Fig. 1. Various seed shapes. The London Clay Formation is a marine geological formation of Ypresian (Lower Eocene Epoch, about 56 to 49Ma) age. It consists of stiff, bluish-coloured clay, which becomes brown when weathered. And it provides one of the most varied fruit and seed floras in the world, which also happens to be the only diverse flora fossil assemblage from the Lower Eocene in Europe. There are 500 or so recognised species, which would have inhabited mangrove and tropical habitats much like Indonesia or East Africa today – bordering a warm, shallow ocean. Commonly found are specimens belonging to magnolia, vines, dogwoods, palms, laurel and bay, with a third of the fossil species present belonging to genera that are still found living today. Fig. 2. A selection of seeds. London Clay seed fossils … Read More
Fred Clouter (UK) The Isle of Sheppey is situated at the mouth of the Thames estuary and is a part of the North Kent marshes. The north coast of the island has about 5km of London Clay exposures that are highly fossiliferous. The London Clay here was laid down between 54 and 48mya, during the Eocene epoch, on the shallow shelf of a semi-tropical sea near the estuary of a major river system. I cannot remember just when it was that I decided to embark on the project of building a website about fossils and fossil collecting in the Isle of Sheppey. However, I do know that a combination of factors led to it. The first was my rapidly growing collection of fossils from this area. The second was the book London Clay Fossils of the Isle of Sheppey that the then Medway Lapidary and Mineral Society had decided would make a good Millennium project. Information covering the fantastic fossils found there was not readily available. The only information often could only be found in old and difficultto- obtain monographs written in the Nineteenth Century or books written in French relating to fish fossils found in Britain or in Belgium and Holland where there are deposits of a similar age. As this book was a collective undertaking, my role was to take the pictures. This meant that I would have access to fossils from many private collections as well as some held in various museums. Lastly and most importantly, was … Read More
Michael E Howgate (UK) Back in the days when I gave my ‘Doctor Dinosaur’ talks to museums, school groups and ‘gifted children’, I would take with me: a plaster cast of the Baryonyx claw; a beach rolled Iguanodon vertebra; and, star of the show, ‘a fossilised dinosaur poo’ (which, in reality, was an Ichthyosaurus coprolite from Lyme Regis). These were some of my collection of props, which helped engage the children through what might otherwise have been a run-of-the-mill slide presentation. Some of the bits-and-pieces I picked up to pass around among the children were a selection of broken and hence dirt cheap Carcharodon megalodon teeth (Fig. 1). (I use Carcharodon instead of the more correct Carcharocles as it is still in common use. The term ‘Megalodon tooth’ is often used by fossil dealers as a short-hand term.) These stood in for the teeth of every child’s favourite dinosaur, the fearsome Tyrannosaurus rex. I would pass the teeth round and get the children to feel the serrated edge as a prelude to explaining how a serrated blade was better at cutting steak – or even a loaf of bread – than a sharper carving knife. “Only try this at home if you are supervised by both parents” was my health and safety rider at the end of this explanation. Fig. 1. Half of a C. megalodon tooth. A cheap and cheerful stand-in for a T. rex tooth. Carcharodon (now Carcharocles) megalodon, which used to be considered the ancestor of the … Read More
Biddy Jarzembowski, Chris Proctor and Ed Jarzembowski (UK) In this concluding part of the mini-series, we show the archaic wet forest at Writhlington (Fig. 9) which is the most familiar palaeohabitat associated with the Carboniferous age of coal. In the absence of flowering plants, the forest was less biodiverse than today’s tropical forest and more varied along the river banks (Fig. 5 in Part 2) than in the swamp. We also look in on the denizens of a forest pool (Fig. 10) and restore an extinct giant millipede (Fig. 11), one of the largest arthropods that ever lived, represented by tracks and body fossils there. An archaeorthopteran insect was seen at a distance in Part 1 (Fig. 3) and a brand-new image of another, but close up, is presented here (Fig. 12). The fossiliferous rock tipped at Writhlington represents only a fraction of Carboniferous time, much more being locked up in the mass of peat that turned into coal. The latter went mainly to fire Portishead Power Station in North Somerset and would have included peatland palaeohabitats not reconstructed here. It is the ancient fresh-water floodplain (making up the miner’s ‘roof shale’) that has been explored in detail so far. More information can be found in:Jarzembowski, E. A. 2004.

Biddy Jarzembowski, Chris Proctor and Ed Jarzembowski (UK) In Part 1 of this article (Writhlington revisited (Part 1): A polychrome perspective), we focused on forest arthropods associated with scale trees (Figs. 1 to 4) that were found in the Coal Measures of Writhlington batch, near Radstock, in southwest England. We now move on to other palaeohabitats represented there some 308 million years ago. All too often, reconstructions and restorations of the Carboniferous combine diverse organisms in a single view of the terrestrial realm. (They are frequently likened to the modern Amazon, but apart from being tropical with luxuriant vegetation, the ancient communities differed in composition, species richness and sedimentary environment.) We have departed from this with several different scenes here based on the fossil assemblages and rock lithologies: mixed forest (Fig. 5), river floodplain (Fig. 6) and river channel, the latter with some large (Fig. 7) and small (Fig. 8) animals. Fig. 5. The mixed forest is depicted on drier swamp margins as near the raised river banks (levees). This diverse community is still dominated by scale trees (Lepidodendron and Sigillaria species) but with an understorey of seed ferns (Alethopteris and Neuropteris spp.) and tree ferns (Pecopteris sp.). The more herbaceous cover is provided by horsetails (Sphenophyllum, Calamites and Annularia spp.). The plant names are given generically because the species are based on details of bark and foliage which are too small to see in the painting. Fig. 6. A muddy, upper delta floodplain with temporary shallow lakes and ponds … Read More
I always wait expectantly for the publication of a new Palaeontological Association guide to fossils and, when they turn up, I am never disappointed. This is undoubtedly another triumph. This guide attempts to bring the diversity of its flora and fauna together in a single work, for the first time.
Biddy Jarzembowski, Chris Proctor and Ed Jarzembowski (UK) Thanks to ‘King Coal’, it is perhaps all too easy to visualise the Carboniferous Period – and especially the Pennsylvanian Subperiod – in black and white or shades of grey. The Earth’s first tropical forests – which gave us peat which turned to coal – were, however, perhaps no less colourful than some modern forests. The long-term project at Writhlington, near Radstock, currently in Bath and North East Somerset (UK), has produced a rich fossil record from the Farrington Formation dating back some 308myrs BP (to the late Asturian (Westphalian D) subage or late Moscovian). Not only has it produced many specimens, but has also allowed meaningful correlation between fossil assemblages and rock types (lithologies) left discarded on the waste tip (batch) of the former Lower Writhlington Colliery. (The finds at Writhlington can be explored by a list of further reading, which will be given in Part 3.) In the closing years of the last century, one of us (Chris) produced several reconstructions in traditional black and white, which illustrated several learned papers and regional museum displays. These included the palaeohabitat as well as selected species. Here, Biddy has applied paint brush and water colours for the first time to these scientific restorations for a new audience – tantalisingly, due to the remoteness of the age of coal. Ed has composed some explanatory notes to accompany the pictures in this three-part mini-series. This year marks the fortieth anniversary of the RJG Savage … Read More
I sat down to read this over Christmas and what a good read it turned out to be. The appropriate word is ‘eclectic’ – because Measures for Measure is written for all us with an interest in the industrial history of Great Britain, and its impact on the landscape, economy, social history and culture. It’s a great read as it dots about linking places and ideas together, with the link always being the geology.
P W Forster (UK) I have many years of experience collecting and cutting agates. It was my wife who originally had an enthusiasm for these beautiful semi-precious stones and it was because of her enthusiasm that I developed an interest that has now become an obsessive hobby for the both of us. Cabinets in our home evidence the wide range of specimen stones that an amateur collector can discover. Each specimen has identiﬁcation labels and is catalogued to show the date and the region where it was found. Before starting my first collecting foray, I obtained as much information on the subject as was available. To this end, I found the book ‘Agates’ by H G McPherson most useful. (This book, together with ‘Agate collecting in Britain’ by P R Rodgers, has been extensively used in the writing of this article.) From my research, it became apparent that the Midland Valley of Scotland contained many of the best deposits of agates in Great Britain. With this in mind, we paid the ﬁrst of many visits to the region. We started searching along the east coast of Ayrshire. This coast abounds with small coves of pebble beaches and large stretches of andersite larvas that stretch out to sea. During the ﬁrst year, we amassed a large amount of what we thought were agates, but closer examination revealed that we had collected some colourful specimens of jasper as well as some lovely quartz pebbles. This ﬁrst attempt had revealed that those agates … Read More
Byron Blessed (UK) As many of us know, a good day’s fossil hunting rarely stops when we leave the beach. However, many people do not know what to do with a fossil once they’ve found it. So, here are a few pointers in the art of fossil preparation. This article will not only outline what equipment you will need but will also give you general guidelines on how to use it. Fig. 1. The various stages of prep-work. Nautilusastercoides, found in the Upper Lias, Sandsend,near Whitby in North Yorkshire, UK. The first thing that any fossil preparator needs (and it isn’t something you can buy) is a lot of patience. The second thing you need is … a lot of patience! This cannot be stressed enough. Fossil preparation is a long, sometimes boring and laborious process and it is all too easy to damage specimens by being too hasty! It must also be noted that fossil preparation is not something that can easily and successfully be taken up overnight. Most of the best preparators have been in the business for decades. To think that you can immediately match their skills over night is naïve to say the least. Like any good hobby or job, practice makes perfect. In addition, it can be very costly to get all the right kit so this can become an expensive hobby. Washing specimens under the tap is a good, first step and will reveal hidden detail by removing unwanted mud and sand. Many clays … Read More
David Mayhew (The Netherlands) When you walk through the countryside,youwill not often come across a vole. However, they are present in most habitats and are one of the most successful groups of small mammals, widely distributed in both Eurasia and North America. Broadly speaking, Voles are blunt- nosed, short-eared, mouse-like rodents and many of them are specialised for burrowing. They can eat hard vegetation such as grasses that are very abrasive due to the presence of silica spicules. Therefore, many species of voles haveevolvedcontinuously growing cheek teeth (that consist of molar teeth: three upper and three lower) as well as the continuously- growing incisors that are typical of rodents. Finding fossil remains of voles This evolution took place largely in the last three million years.For this reason, fossil remains of voles are very useful for helping us unravel the stratigraphy of deposits from the Pliocene and Pleistocene periods. And, as you can see from the photographs, they are beautiful objects in their ownright. We are talking here of quite small fossils, for example, the molar teeth are between 1 and 3mm in size. So, where and how are they found? Many, even thousands of specimens, can be found in cave and ﬁssure deposits, such as Foxholes at High Wheeldon in Derbyshire. Often, such localities have no stratigraphic context other than the fauna contained in the sediments. However, the material may be very complete (skulls, lower jaws and limb bones). Fig. 1. Remains of vole Microtus sp. from Foxholes cave, High … Read More
Joe Shimmin (UK) The beauty and variety of the microfossils of Folkestone’s Gault Clay cliffs has amazed me ever since I was about 14 years old. At about this time, I had the good fortune to see some samples sent to me by Jim Craig, who I had met at the site. These microfossils roused in me such enduring enthusiasm that I eventually wrote an article entitled Marvellous microfossils (Part 1): Collecting Microfossils from Folkestone on how to process Gault Clay to obtain. This is the second article on this topic. Apart from the fact that the Forams, Ostracods and other microfossils found in the residue left by wet- sieving Gault Clay are interesting and unusual, in themselves it is also a bonus that there are vastly more of these fossils, in terms of numbers, to be found than the larger fossils that people usually go there to collect. If you collected hundreds of these larger fossils from a site in one go, you might be seen to be selﬁshly depriving other collectors of the opportunity to collect some for themselves. However, within 1kg of Gault Clay, there are literally thousands of microfossils. Therefore, removing a few kilograms of Clay from the site will do no damage whatsoever. So, within reason, you can build up a huge collection of a vast variety of microfossils with minimal impact on the site. These reasons have led me from writing the article referred to above to attempting to write a small book (or, … Read More
This book is truly sumptuous, and yet is also a comprehensive discussion of William Smith’s maps (including the revolutionary ‘A Delineation of the Strata of England and Wales, with part of Scotland’) and career. It is beautifully produced, printed on quality paper and the full colour illustrations are outstanding.
Joe Shimmin (UK) The Gault Clay outcrop, at Folkestone in Kent, is a wonderful place to ﬁnd all manner of fossils. Over 100 species of ammonite have been found and there are also barnacles, belemnites, bones (reptile and ﬁsh), coprolites, corals, crinoid pieces, crabs, crocodile teeth, ﬁsh teeth, gastropods, (deep breath) nautiluses, ccaphopods, shark teeth, vertebrae (bony ﬁsh, shark and, occasionally, reptile), worm tubes and more. These fossils can be found in the clay cliffs and also at the base of the cliffs, washed out from above. But there are other fossils to be found at Folkestone that are less conspicuous. Fig. 1. The cliffs at Folkestone. An individual, who is new to the site, may be forgiven for thinking that the larger fossils are all that Folkestone has to offer. If this were so, it would still be a fantastic location. The fact is, however, that this is not the case. Folkestone’s Gault Clay also has a rich and varied, beautifully preserved, microfossil fauna. Fig. 2. Enlarged images of microfossils from the Gault Clay at Folkestone. Microfossils are trickier to ﬁnd and collect than their larger counterparts. They are hard to see, often quite fragile and difﬁcult to handle. However, with a small amount of perseverance, along with a good technique and a few pieces of apparatus, anyone will be able ﬁnd hundreds of these beautiful and intricate fossils and, in no time, build up quite a collection. While on a fossil hunting trip to Folkestone, it is well … Read More
Jon Trevelyan (UK) In Issue 60 of Deposits, I restarted my occasional series on UK geological museum with a visit to the Booth Museum in Brighton (see Geology museums of Britain: The Booth Museum of Natural History, Brighton). Having more time on my hands than I would like during the Covid-19 lockdown, I got to thinking about a recent visit I made to the Museum of London in the Barbican in the City of London. I expect that most people would not link this excellent museum to anything geological, but they would be wrong. In fact, there are many exhibits from the prehistory of the capital and these include fossils of animals that lived in the region and stone tools from our ancient ancestors, who shared the area (Figs. 1 and 2). Fig. 1. A somewhat demonic looking auroch (Bos primigenius), which is an extinct species of large, wild cattle. These were domestic during the Neolithic Revolution, such that modern breeds share characteristics of the aurochs. Fig. 2. Flint tools found at Swanscombe. In fact, the museum’s oldest items date back to when London was tundra and the local population would fit into one of its iconic double-decker buses. During these times, there were several different species of humans occupying the Thames Valley, firstly as hunter gatherers and only later creating fixed settlements. Human and animal species roamed the open steppe-tundra, until their final disappearance about 30,000 years ago; and Neanderthal groups probably shared the valley with modern humans. And … Read More
This little guide contains excursion guides explaining and exploring the relationship in the UK between hillslope gully erosion and the response by stream and valley systems within the Howgill Fells of Cumbria. The author’s choice of this area rests on the fact that it is one of the most active landscapes in Britain from the point of view of erosion.
Carl Mehling (USA) Things aren’t always what they seem. The fluidity of information and the frailties of human memory allow for a lot of corruption. Innocent assumptions are made. Sloppy mistakes take place. Unforeseeable accidents occur. And deliberate subterfuge is always there as an option when these others fail. Throw a little time at them and mis- and disinformation get lithified, entrenching them in the human psyche and culture. Fighting for accuracy is a continuous battle. A wing and a prayer Once almost considered throw-away parts of the bird, chicken wings have soared to unimaginable heights since their transformation into ubiquitous bar food in the 60s. Buffalo wings are so absurdly popular in the US that possibly-calculated rumours often circulate that a wing drought is coming, causing the requisite panic. Sports bars riot over this dearth, prompting half-serious suggestions of breeding chickens with more than the pathetic pair that their lineage has provided. Anything this popular inevitably spawns feuds over priority: Who gets to claim bragging rights for such a powerful, lasting and lucrative phenomenon? Fig. 1. Were the origins of Buffalo Wings in a science pub or a brew pub? This certainly happened with Buffalo wings. I’ll spare you the gory details, but although hard to prove definitively, most have settled on the idea that the Anchor Bar in Buffalo, NY began this tangy trend in 1964. However, as it turns out, it can be demonstrated that the origin of buffalo wings actually happened elsewhere, and in 1962. Or, … Read More
Dr Paul D Taylor (UK) Fossil collectors often overlook, or worse discard, bryozoans. There are several reasons: some bryozoans are small and not easily spotted in the field, others are mistaken for non-descript sponges or algae, while bryozoans cemented to the surfaces of other fossils can be cursed for detracting from the value of the main fossil. But bryozoans are fascinating fossils in their own right and ought not to be ignored. Bryozoans are a morphologically varied phylum of colonial invertebrates. The myriad of colony-forms they exhibit reflect adaptations that evolved to allow them to prosper as immobile colonial animals living on the seabed and feeding on passing plankton (Taylor, 2020). The majority of the more than 6,000 bryozoan species living today possess resistant skeletons of calcium carbonate, and the calcareous skeletons of fossil bryozoans are abundant globally in rocks ranging back to the Early Ordovician, some 480 million years. Fossil bryozoans in Britain occur in marine sedimentary rocks from every post-Cambrian geological period except the Triassic. Ordovician bryozoans can be found in the Welsh Borderlands and in southern Scotland, Silurian bryozoans in the West Midlands and Shropshire, Devonian bryozoans in Devon, Carboniferous bryozoans in the Pennines and other places where the Carboniferous Limestone outcrops, and Permian bryozoans in the Magnesian Limestone of northeast England. Previous contributions to Deposits have described bryozoans from the Chalk of Late Cretaceous age (Taylor, 2018) and the Pliocene Coralline Crag of Suffolk (Taylor and Milne, 2009). Here, I focus on British Jurassic bryozoans. Jurassic … Read More
Mary Anning was clearly one of the most significant characters of eighteenth century science and possibly of all time, particularly in the realm of palaeontology. I am not sure that she is quite as unknown (certainly in the UK) as the American author this excellent little biography claims, but she certainly should be better known.
The 71st GA guide has been published and what a good one it is too. It’s not really my area (I prefer palaeontology) and covers quite a specialist subject, but this is certainly interesting. And this is surely the point of GA guides – to cover topics that other publishers might be reluctant to consider.
