Geology Museums of Britain: Portland Museum, Dorset

Jon Trevelyan(UK) Fig. 1. A huge Titanites giganteus adorns the doorway. I visited this little museum a while ago while on a Geologists’ Association field trip. I have passed it several time and always loved the large Titanites giganteus above the door (Fig. 1) of this picturesque cottage (Fig. 2). As a result, I had always wanted to visit, but more particularly I want to see the famous fossil turtle (Fig. 3) that is exhibited there. Fig. 2. One of the two seventeenth century cottages making up the museum. Fig. 3. The lovely fossil turtle at the museum. In fact, Portland Museum is a lovely example of a local museum containing (among other things, geology (Fig. 4), in this case, tucked away in a beautiful part of the ‘island’ in two seventeenth century cottages, near Rufus Castle and the popular Church Ope Cove. Fig. 4. Some of the geological exhibits at the museum. The Isle of Portland in Dorset represents the most southerly point of the Jurassic, which is a UNESCO designated World Heritage Site and famous for its geology, fossils and geomorphology. It is joined to the mainland by the equally famous Chesil Beach but has always been regarded (not least by its inhabitants)as separate from the mainland, and this is reflected in the museum’s collection. That is, Portland Museum does not just contain geology and palaeontology; its exhibits also reflect the Isle’s history and people. Portland Museum was founded in 1930 by Dr Marie Stopes, renowned for her … Read More

Ghughua Fossil National Park, India

Khursheed Dinshaw (India) The Ghughua Fossil National Park is located in the state of Madhya Pradesh, India and contains plant fossils that are more than 65 million years old. It covers an area of approximately 27.34ha and consists of a museum and fossil trail. The fossils inside the museum are on display in neatly arranged glass showcases. The most popular exhibit is the Eucalyptus tree fossil, which is kept on a bed of sand (Fig. 1). It was found in Ghughua and what makes it a highly coveted fossil is the belief that it originated from Gondwana (see below). Fig. 1. A Eucalyptus tree kept in the museum. The fossil trail is a walkway where visitors can see the fossils in their natural setting. Since multiple fossils were discovered at one location, they are placed on circular platforms at that spot by the side of the walkway (Fig. 2). Fig. 2. Multiple fossils found at Ghughua. It is due to the untiring efforts of Dr Dharmendra Prasad, who was the Statistical Officer of the district, that the fossils and park gained their due prominence. Fifty two years ago, S R Ingle from Science College in Jabalpur and Dr M B Bande from the Birbal Sahni Institute of Palaeosciences in Lucknow spent time studying and identifying the fossils and their contribution is significant. On 5 May 1983, Ghughua was declared a Fossil National Park and a sum of Rs 150 lacs was allocated for developing it. The fossils that can be … Read More

Pennsylvania’s forests looked different in the Carboniferous and Early Permian

Deborah Painter (USA) A singer named Perry Como caused this article to be written. Perhaps it would be more correct to credit his statue. My friend Richard and I took a road trip in June 2018 to a conference in Cranberry Township, Pennsylvania, USA for a three-day weekend. On Sunday afternoon, we were facing a seven hour drive south back to our homes. Fortunately, the weather was sunny and mild, a good way to conclude a trip that had been plagued with thunderstorms earlier. We were both tired, but Richard allowed me to stop off Interstate 79 to Canonsburg, Pennsylvania to see a statue in honour of Perry Como, an American celebrity of the mid-twentieth century. I admit I didn’t know why I wanted to see it, since I am not especially a fan of the recording artist and television star, and neither is Richard. However, I was curious about it because I had read that it continuously plays music. I also thought Canonsburg (Fig. 1), a quick turn off the Interstate highway in Washington County, might be a good stopping place for us to find a restaurant before proceeding on the long journey back. Fig. 1. Canonsburg is an older suburb of Pittsburgh, Pennsylvania USA in Washington County. (Credits: Deborah Painter.)

In the footsteps of T-rex and other prehistoric giants: my trip to Hell Creek, the Green River Formation and the Niobrara Chalk

George Corneille (UK) It was Christmas 2005 and I received a phone call from the USA from my good friend, Terry Boudreaux. He asked if I wanted to join him and his boys, Christopher and Evan, on a trip to hunt dinosaurs in Hell Creek in South Dakota, fossil fish in Kemmerer, Wyoming and Cretaceous marine life in the chalk formations of Gove County, Kansas. Well, he didn’t have to ask twice and, in June of 2007, I arrived in Chicago to begin my 4,500 mile road trip to some of the most famous fossil sites in the world. On the morning of Sunday, 25 June 2006, we left Chicago to begin our fossil adventure. I was full of anticipation, dreaming of a finding a mosasaur or maybe a four-inch T-rex tooth (or even just a fossil fly). On the first day, we drove to Sioux Falls, South Dakota, arriving the next day in Rapid City S.D. where I had an opportunity to visit the Black Hills Institute and see their stunning collection of dinosaur fossils. I suppose the most impressive fossil was the complete Triceratops lying in situ, as he has done for the last 65 million years, and the giant skull from a Deinosuchus, the massive prehistoric crocodilian. We continued our journey and, that night, arrived in Buffalo, South Dakota where we would spend the next few days hunting dinosaurs. Fig. 1. Outside the ranch house in Buffalo, S.D..

A crinoid find and a brief history of collecting these animals

Fiona Jennings (UK) I am a collector of fossil crinoids that, along with many other types of fossils, are common on the coast of North Yorkshire. The best crinoid fossil I have found so far is the large block of jumbled stems pictured. I found it at Skipsea, a few miles from Tunstall, on the Holderness coast, one November a while ago. The block measures 18 inches across, is 6.5 inches thick and has a circumference of 23 inches. I was totally surprised when I saw it resting on the mud, as I’d only been on the beach for about ten minutes. My friend Harry tells me that this block is an erratic, carried to the beach from further north, by glacier ice during the last glaciation. Fig. 1. The block. I always have fun on my fossil hunting trips, but the biggest laugh of this particular day came as I tried to get the fossil off the beach. After finally squeezing it into my husband’s rucksack, I then had the trouble of lifting the bag onto his back. Fortunately, he managed to lug my find back to the car, because it was definitely coming home with us whether he liked it or not! Fig. 2. Magnified view of the crinoid block. I find crinoid fossils fascinating, but the history of their collection interests me the most. In the past, disc-shaped segments from their stems were used to make necklaces and rosaries. As a result, they were once known as … Read More

A very brief Introduction to the Quaternary

By Joe Shimmin The Quaternary comprises the Pleistocene and the Holocene and is the youngest of the geological periods. It dates from approximately 1.8 million years ago right up to the present, with the large majority of this time being filled by the Pleistocene. The Holocene spans a geological ‘blink of an eye’, beginning only 10,000 years ago at the start of the present interglacial and continues today. What sets the Quaternary apart from other geological periods is a suite of high frequency climate fluctuations, with very cold stages being interspersed by warmer stages. This type of climate fluctuation is believed to have occurred at various other times in the Earth’s history, but most of the evidence for these has been wiped out over millions of years. However, the glacial/interglacial or warm/cold stages of the Quaternary have, in many cases, left us enough evidence of their existence for the Quaternary scientist to be able to attempt to reconstruct these past environments with some degree of success. Fig. 1. Glacial beds at Benacre, Suffolk Serbian mathematician, Milutin Milanković, formulated the accepted theory for why climate oscillations have occurred in this period, in the first half the twentieth century. According to ‘Milanković, Quaternary climate was, and is, influenced by three factors: Factor 1: the shape or ‘eccentricity’ of the Earth’s orbit around the sun, which varies over a cycle of approximately 100,000 years.Factor 2: The tilt or ‘obliquity, of the Earth’s axis, which varies over a cycle of approximately 41,000 years.Factor 3: … Read More

Down and dirty at a dig: a dinophile’s dream comes true

By Elena Victory “You really should go on a dig” was the advice of a dear friend during the long, rainy winter of 2005. I was just gearing up to teach my annual, introductory paleontology class at a small college near my home outside Portland, Oregon. “Where?” I asked. “Who specialises in fanatics who read lots of dinosaur books and dream a lot, but has never dug up a real dinosaur?” She smiled and said, “I think Nate Murphy’s program would be good for you”. It unfolded from there. I emailed Nate to find out availability. He emailed back, directly I might add. And so, I found myself outside of Billings, MT en route to my first real dig. It was a beautiful landscape: a few lonely Ponderosa pines stood like silent sentinels over a grassy landscape dotted with spurges, thistles and wormwoods. Through the eyes of a botanist, it didn’t look like dinosaur country to me. That night, after a group of 35 excited diggers had made camp and their introductions, we were given a little history. The next day, we were going to dig our awls and shovels into the “Mighty Morrison”, a huge geological layer cake of shales and mudstones spanning several states and several thousand square miles. The Morrison graveyard also records a story of climate change. Early in the Jurassic period, Apatosaurus roamed on its home range encountering arid seasons part of the year and deluges the rest of the season (poor thing, I thought, … Read More

Jurassic Gorge

By Dr Susan Parfrey About 95km south of Rolleston, in the southern part of central Queensland, Australia, is a national park that contains the Carnarvon Gorge. The gorge is over 32km in length and is formed of towering white sandstone cliffs. It has almost everything a visitor could want – beautiful scenery, wonderful Aboriginal rock paintings and a garden of moss with a magic waterfall, plus King Ferns, the largest ferns in the world. So what’s missing? Well, obviously, Jurassic dinosaurs. An impression of how these dinosaurs may have looked. © SMP. This is one of the most popular national parks in the state and has over 30,000 people visiting every year. Over the years, you would imagine every centimetre of rock has been carefully studied and, in particular, the ‘Art Gallery’ Aboriginal rock paintings, some of which date back 3,600 years. Imagine the surprise in 1992 when some tourists told the Park Ranger they thought there were bird footprints in a rock at the Art Gallery. The ranger examined the site and, sure enough, there were some marks on the rock. But were they footprints? The Park Ranger took photographs and sent them to the sloe palaeontologist at the Geological Survey of Queensland in Brisbane. Map of Australia showing the position of Brisbane and Carnarvon Gorge.

Finding Ophthalmosaurus – the eye lizard

By Paul de la Salle Ophthalmosaurus – the ‘eye lizard’ – is so called because of its enormous eyes, presumably of crucial importance when diving to enormous depths in the Jurassic seas in search and pursuit of its favourite prey, the belemnite. This was a large ichthyosaur, supremely adapted to its marine environment. Some fossil collectors think it should be called ‘Ribosaurus’ on account of the number and size of its ribs that are usually broken into hundreds of pieces when found. Fig. 1. Block as found – 24 June 2007. Fig. 2. Ribs. Individual vertebrae and rib sections of this, the only ichthyosaur known from the Lower Oxford Clay, are fairly common finds. However, I was lucky enough to find a partial articulated skeleton this summer, in the drainage ditches of a Wiltshire gravel pit. Fig. 3. Concretion before cleaning. Fig. 4. Another concretion before cleaning. Recent heavy rains had washed away some of the clay from the bank exposing a large pyritic concretion packed with bones, including a humerus. When I dug into the bank, I was amazed to find both front paddles, including both humeri and about 50 paddle bones. Many of the bones were fused together in life position. Fig. 5. Front and rear flipper. Fig. 6. The left paddle. Fig. 7. Loose vertebrae. Over the next week or so, I recovered quite a bit more of the skeleton but the head had been washed away by one of the floods that had deposited the gravel … Read More

SEACHANGE sets sail: Science on the high seas

Jack Wilkin (UK) During April and May 2022, I had the fantastic opportunity to participate in a research expedition to the North Sea and Iceland on the RRS Discovery, as part of the SEACHANGE project. The following article is a brief description of the science that happened on the ship. What is the SEACHANGE Project? SEACHANGE is a six-year research project funded by the ERC Synergy Grant Scheme (part of the EU’s research and innovation programme, Horizon 2020). It is jointly run by the University of Exeter (UK), Johannes Gutenberg University Mainz (Germany) and the University of Copenhagen (Denmark). This is a collaborative project with scientists worldwide, from master’s students to professors working diligently to answer the question: What were the oceans like before large-scale human impact? To answer this question, we need to test the scale and rate of biodiversity loss resulting from fishing, whaling and habitat destruction over the last 2,000 years in the North Sea and around Iceland, eastern Australia and the Antarctic Peninsula. In addition, we need to find out more about the earlier transition from hunter-gatherer to farming communities in northern Europe around 6,000 years ago. However, before answering this question and starting to generate data, we first needed the raw materials. Because we were monitoring the oceans, we needed to go to the sea to gather our samples, so we need a boat … a very big boat. The RRS Discovery. The RRS Discovery (Fig. 1) is one of the most advanced research ships … Read More

British fossil elephants

By Adrian M Lister Fig. 1. From a realistic scale model at the Natural History Museum, London. Note the sloping back and the double ‘finger and thumb’ at the end of the trunk. (© Natural History Museum, London.) The elephant family (Elephantidae), like that of humans, originated in Africa. Finds from the late Miocene of southern and eastern Africa show that, by between seven and six million years ago, true elephants had arisen, probably from advanced mastodonts, which are related to stegodons. Between those dates and about four million years ago, the earliest representatives of the three great stocks of elephants – the African elephant (Loxodonta), Asian elephant (Elephas) and mammoth (Mammuthus) all make their appearance in the African fossil record. Loxodonta, of course, stayed in Africa, while Elephas eventually migrated north and east into its current range in south-east Asia. The first true elephant fossils in Europe are of the Mammuthus lineage. In Britain, these first make their appearance in the Red Crag of Suffolk, now dated to around 2.6 million years old. The fossils are not common, but three well-preserved molars from Rendlesham can be seen in Ipswich Museum. This material has recently been attributed to the species Mammuthus rumanus, on the basis of the primitive appearance of the back molars with only ten complete enamel loops (Lister and van Essen, 2003).

Fossils from Denmark (part 1)

By Niels Laurids Viby Denmark – why on earth should anybody in the UK go to such a strange place – where people, among other things, drive on the wrong side of the road and speak a funny language? And why write something for Deposits on the subject at all? You can find fossils from almost every time period apart from a few in the UK. For example, you can find them from the very top of the Cretaceous period (Maastricien) and the Lower Palaeocene period (Danien). However, these particular geological periods, especially the Danien that was, after all, named after a site in Denmark are also found in many places in Denmark. Moreover, at one site, you can actually access the KT border and get a sample from the famous (but thin) band with high concentrations of iridium. Of course, most fossil collectors concentrate on what is found close to home, and for good logistical reasons. However, for those who want a broad collection covering the development of life or for that matter a mass extinction, a holiday in Denmark is a good option for filling a gap without having to drive long distances – Denmark is a rather small country! In this first article on Danish geology, I will provide the reader with two things. Firstly, a short description of Danish geology, including what is legal to collect and what is not and secondly, a description of a Danish speciality – Lower Eocene diatom clay, the ‘moler’, which … Read More

The Elgin Marvels

By Neil Clark (UK) Not to be confused with the Elgin Marbles, the Elgin Marvels actually come from the Elgin area of Scotland. They are well known fossil reptiles and their footprints, of Permo-triassic age, that were collected from old sandstone quarries mostly over a century ago. They are partly what inspired me to take up palaeontology although, at that time, I had never actually been to Elgin, nor ever seen the fossils. It was through the lectures of Professor Euan Clarkson of Edinburgh University in the 1980s that I first became aware of these animals. However, it was not until much later that I came face to face with the Elgin Marvels themselves. Sketch map of the geology around Elgin. In the summer of 1996, while recovering from a broken leg as a result of dinosaur hunting on the Isle of Skye (see my article in Issue 12 of Deposits), I was asked to give a talk on my exploits at an Open University Summer School in Edinburgh. Most of the talk was concerned with the study of dinosaur footprints, their interpretation and identification. After the lecture, I joined the students in their usual nocturnal social discussion groups. It was at this time that I was approached by one of the students who claimed to have seen some ancient footprints in the bedded sandstones near Elgin. The student, Carol Hopkins, invited me to Elgin to have a look at the footprints she had found. I could not pass up … Read More

Building a fossil preparation box

By Chris Pamplin I have been collecting fossils on and off for about 36 years and it’s not since I lived at my mother’s home, some 25 years ago, that I have been really organised about cleaning fossils for display. Although I am a professional fossil hunting guide, my interest in fossils has always been as an amateur collector and, for many years, my main fossil cleaning tool was an electric engraver, which cost £30 back in the 1980s. At my last rented house, the brick barbeque with a sandbag on it was my outdoor cleaning station. It is only since moving into a new house and finally buying a shed that I have got myself sorted. Fig. 1. The dimensions of the box. So here is how to make a fossil preparation box, like the one that I now have ready for use in my shed, which will keep the dust at bay and cut noise levels as well. You can use it with an electric engraver or, as I now do, with a compressed air pen specially adapted for palaeontological work. Fig. 2. An example of an Air Abrasive Blaster (125psi). The box described in this article was built from odds and ends that I had laying around, left over from various DIY projects. However, the materials can also be bought new if you are not in a position to recycle. The sides and base are plywood and the back and top are an old estate agents board … Read More

Bryozoans: more than meets the eye

By Paul D Taylor A few years ago a survey was undertaken of the changing proportion of bryozoans relative to other fossils at an Ordovician locality near Cincinnati popular with fossil collectors. The site was revisited annually over a ten-year period, random collections of fossils were made and the numbers of crinoids, trilobites, brachiopods, bryozoans and other fossils were counted. At the beginning of the study, about 25% of the fossils consisted of bryozoans, by the end the proportion had gone up to 75%. The author of the study referred to this phenomenon as “bryo-enhancement”. Of course, the bryozoans had not been increasing in an absolute sense, rather visitors to the site had preferentially collected other fossil groups, causing the proportion of bryozoans left behind to rise. The Cincinnati study is a fair reflection of the unpopularity of bryozoans among fossil collectors. Fossil bryozoans generally languish unloved among the sponges and trace fossils in the bottom drawers of collectors’ cabinets and are seldom seen for sale in fossil shops or on the Internet. Why should this be? Part of the reason is that few bryozoans have the aesthetic appeal of such fossils as ammonites or trilobites – well at least to the naked eye. They are also difficult to identify and all too often mistaken as corals, sponges or algae. But another reason is that bryozoans have a low public profile. Unlike molluscs and crustaceans, you won’t find bryozoans on the menu at fish restaurants, even in the Far East. … Read More

Isotopes provide key insights into dinosaur lives

Jack Wilkin (UK) Isotopic geochemistry has a long history in the palaeosciences since Urey (1947) first suggested that 𝛿18O from fossil calcite could be used to estimate past temperatures. Stable isotope analysis of fossils has become an increasingly important method for gathering dietary, physiological and environmental/climatic information from extinct species in terrestrial and aquatic ecosystems. The benefits of these analyses come from the geochemical fingerprint that an environment leaves in bones, teeth and soft tissues. Ongoing studies of living organisms have found that the stable isotope composition of several light (hydrogen, carbon, nitrogen, oxygen and sulphur) and even a few heavy (calcium and strontium) elements are useful tracers of ecological and physiological information, and many of these can be similarly applied to the study of dinosaurs. Over the last few decades, stable isotopes have greatly expanded our understanding of dinosaur palaeobiology and diet. Thermoregulation in an animal is affected by metabolic rates. Therefore, by learning more about dinosaur thermoregulation, we can make an accurate interpretation of their metabolic strategies, life histories and even evolution. Thermoregulation – the internal body temperature of an animal – can be ascertained by directly measuring oxygen isotope ratios in their bones.  Isotopes and other geochemical proxies can also help reconstruct dinosaur diets and food webs. Below, I will briefly discuss the applications of oxygen, carbon and calcium isotopes in dinosaur research. Diagenesis Before continuing, it is worth discussing the effects of diagenesis – the process by which fossils are formed. Diagenesis is the term that … Read More
