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
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
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
There is much to be enjoyed in this engaging book by Roy Plotnick, in which he brings the modern practice of palaeontology – and palaeontologists themselves – vividly to life.
Clay Carkin (USA) My ﬁrst exposure to fishing in Scotland came about while reading comments made on the UK Fossils Network fossils discussion page. Initially, I thought that it would be about highland trout and salmon. However, in an interesting series of events, my life was to be enriched and … Read More
The blurb for this book states that it will “profoundly affect the way paleontologists and climatologist view the lives of ancient mammals”. However, not being either a (professional) palaeontologist or climatologist,but having read it with interest, I am not sure that is correct. Anyone with an active interest inwhat the interactions of ancient mammals and their environments tell us about the presentand future will be interested in this well-written and engaging book.
Steven Montes (UK) I was using my metal detector in the foothills of Tucson, Arizona. As I was walking back to my truck, I caught sight of an unusual-looking rock lying on the ground. I picked it up and noticed a fossil that looked suspiciously like the head of a … Read More
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

Dean Lomax, sometime author of articles in Deposits magazine, is certainly making a name for himself, and has been now for many years. For instance, in January 2022, he was on television explaining about a remarkable find at Rutland Water Nature Reserve. And now he continues his admirable efforts for popularise his chosen academic subject – palaeontology – in this fascinating book about the fossilisation of behaviour.
Ken Brooks (UK) On 26 September 2006, the BBC television programme South East Today featured a report about dinosaur foot-casts that had been discovered “somewhere along the beach near Hastings”. The following day, Dale Smith and I, who are both members of the Hastings and District Geological Society (HDGS), decided … Read More
I recently reviewed another of the guides in Crowood Press’s excellent “Landscape and Geology” guides, which was undoubtedly a great read. And this one is equally good, with great, full colour pictures, maps and diagrams, and easy to read text, with descriptions of interesting walks and what can be seen on them.That is, there are easy-to-understand explanations of how the rocks formed and how the geology affects the landscape, and there is also an n exploration of the long human story of the landscapes.
Niels Laurids Viby (Denmark) I am a Danish architect and, occasionally, I get the chance to travel to different countries on study tours to look at buildings and get inspiration for the work we do back in Denmark and England (we have an office in London). In September 2006, I … Read More
Paul Pursglove (UK) There is a wonderful story about a trilobite found within the footprint of a carnivorous dinosaur. This apocryphal tale is probably true. Fossil rocks can be eroded and fossils like trilobites, can be re-deposited in softer sediments at later times, perhaps even during the time of the … Read More
This is another guide in the excellent “Landscape and Geology” series of local geological guides published by The Crowood Press. And this is as good as the others. Admittedly, it has a wonderful subject matter, because the Isle of Wight is a geological gem with its 110km long coastline displaying a range of rocks dating from Lower Cretaceous to Oligocene age. I know from personal experience that many of its sands and clays contain collectable fossil bivalves and gastropods, and its famous dinosaur footprints attract attention from both geologists and tourists, with always the possibility of finding a bone or two.
Anna Gill (UK) This plesiosaur vertebra column with ribs was found in the early summer, on the Black Venn between Charmouth and Lyme Regis in Dorset, in the UK in 2004. It had been raining for a number of days and parts of the cliffs had turned to liquid mud. … Read More
Brandon Lennon (UK) My kind of collecting requires collectors to be in the right place at the right time. Science directs fossil collectors to the right place, but it is good luck that puts them there at the right time. The latter is often referred to as “serendipity” and what … Read More
I have to admit, I was beginning to wonder where Prof Rory Mortimore’s update of his excellent Chalk of Sussex and Kent was. And now I know. It wasn’t a second edition he was working on, but this magnificent magnum opus in two volumes covering a vastly greater area than that other guide. And the wait was more than worthwhile. The thoroughness, writing quality, content and publication standards are superb.

Deborah Painter (USA) On a cool, early December day in 2020, my friend David Hawk and I decided we simply had to search for fossils after not doing so for months, and also not be stopped by the chill or the coronavirus. Rather, we would prepare for both. We set … Read More
Paul D Taylor (UK) Many fossil collectors will have been disappointed to discover mollusc and brachiopod shells ‘disfigured’ by crust-like coverings of oysters, serpulid worms, barnacles or bryozoans so firmly cemented to the shells that they cannot be removed. However, rather than discarding these encrusted shells, it is worth considering … Read More
Dr Kendal Martyn (UK) Spectacular “spiny” adaptations of the Devonian (about 380Ma) trilobites of Morocco are well known. Free-standing spines, sometimes up to one hundred on a single specimen, make for spectacular (if fragile) specimens. Historically, similar species were first recognised way back in the 1880s by the classic work … Read More
