The Art of Extinct Animals: Pop-Up Palaeoart Exhibition

Posted on Updated on

On Wednesday 13th December King’s College London, in association with the Popularizing Palaeontology Workshop II, hosted a pop-up palaeoart exhibition “The Art of Extinct Animals” featuring some of the UK’s leading palaeontological artists who showcased their artwork and talked about how they go about reconstructing extinct animals and lost environments.

The one-off event engaged with questions like: How can artists reconstruct and recreate the life of the past? What challenges, techniques and difficulties are there in this process?  How does the history of palaeontological artwork affect current conventions in the field?  And what does palaeontological artwork tell us about the relations between science and art? The palaeoartists featured were Bob Nicholls, Mark Witton, Beth Windle and John Conway.

The first talk, delivered by Bob Nicholls, was ‘No, we don’t make it up! Palaeo-reconstruction explained from the inside-out.’

Bob used his reconstruction of Psittacosaurus as a case study to describe his process of building a physical representation of a dinosaur from its fossil, beginning with taking many detailed photographs and measurements of the fossil, including 3D prints to help reconstruct the skeleton and whatever traces remain of details of skin and soft tissue. He then considers the soft parts such as musculature and skin, drawing on evidence on the fossil for them, and considers the creature’s respiratory, digestive, circulatory, nervous and other systems and how these might have been laid out in the creature’s body.  We can draw on living creatures to help imagine this.  Bob stressed that it is important to overcome preconceptions of what the animal may have looked like; in other words, let the science speak.)

Bob creates palaeoart both traditionally (paint and brushes), using software and also as sculpture.  Psittacosaurus is a sculpture so the next steps were to create an armature and clay model which was then coated in silicone to preserve detail then in fibreglass to keep it stiff. The sculpture was then cast, after which it needs to be repaired and tidied up before the final stage of painting takes place.

When deciding which colours to use it can be difficult or impossible to know but scientific developments are progressing constantly and new techniques enable us to learn more from fossils than ever before.  Melanin preserved in fossils indicate likely colours.  A good deal can also be surmised by considering the environment inhabited by the creature, evidenced by the other fossils found alongside, trace fossils like coprolites and the geographical location of the creature at the time of death and likely climate. For example, countercolouration is determined by environment – the amount of light, affected by latitude and habitat, determines the degree, acuteness and position on the body of countercolouration. By placing the model in a similar environment to that it is thought to have inhabited you can assess and inform decisions on how to place countercolouration. Other considerations include carotenoids, porphyries, pterines and purines in fossils, which also inform colour, and patterns in nature.

Next to speak was Mark Witton, whose topic was ‘The science of extinct animal life appearance: why “what did it look like?” is not just a question for palaeoartists (or children).’

Mark observed that it is natural to look at a fossil and wonder “what did it look like?” – palaeoart is about answering that, not by making it up but through scientific research. Palaeoart is more than basic anatomy – lots of new science is constantly revealing more information. So is palaeoart only to inform the lay person/children (non-specialists)? Is it too unknowable/speculative/scientifically meaningless? Is it not relevant to other fields of science? Can palaeoart serve science? Yes. Mark took us through examples of how fossils lead to the artist considering what the remains tell us about the animal and therefore how to depict it.  Considering Arsinoitherium (an extinct horned mammal from the Eocene), the horn bone is not dense so what covered it to make it strong? Nature tells us this was likely a keratin sheath.  Keratin rarely fossilizes so we cannot see it in the fossil so this makes us ask “what did it look like?” and question how the horns were used. Different horn types exist in modern nature which can be compared to fossils for similarities and the type of headgear extrapolated.

Considering Triceratops, it is hard to predict shape of the horn from the bone fossil because it isn’t the complete story so you need to think beyond that and consider how horn grows. For triceratops the horn shape reconstruction tells us the shape changes with age as a result of how horn grows, adding layers within the horn and pushing the earlier layers out and up. Taking another example, Tanystropheus, the fossil might be interpreted as a marine reptile with a long neck or a shore-based angler.  Studying the skeleton more closely, tong cervical ribs and a large scapular area for muscular attachment gives power to lift and support the neck. Since this musculature and skeleton would not be necessary in water because water alone would provide sufficient support to the neck we can predict that the creature was a land based fisher.

So, the inquiring mind of the palaeoartist informs the artist how to build the creature up from bone to flesh, which habitat to place it in and how it interacts with other creatures in battle, mating and feeding.  At the same time this rigorous inquiry and the resultant art feeds back into science, providing new hypotheses and giving context to scientists to then inquire further too.

Finally, Mark drew audience attention to a forthcoming publication, “The palaeoartists handbook”. Which is out in 2018 and published by Crowood Press.

The next speaker was emerging palaeoartist Beth Windle, whose topic was ‘Illustrating Mammals from Specimens, Life & Location.’

Beth’s primary artistic focus is the Hyena, a creature known and rercognised by most people in its modern form but which would have looked dramatically different during the Pleistocene due to a far cooler climate.  Although genetically the same species as modern Hyenas, those of the Pleistocene would have borne thick, fluffy coats and predated on different animals to today.  Beth strives to understand intimately how this creature and its environment would have looked and portray this in her art.

Beth spoke with passion about how good palaeoart must be informed by drawing from real life observation rather than relying on past art or Google.  As an example, when it snowed recently Beth went out and sketched to capture the English Pleistocene-like environment.  She recommended artists visit museums and collections and handle and draw real specimens and visit zoos and wildlife parks and observe and draw from life and real animal movement. Whilst we might not know exactly what a creature looked like, if we can understand its build and it’s habitat, and we really know how to draw animals and landscapes which contain movement and life, we can create good palaeoart.

Finally the audience heard John Conway expound on ‘Paleoart is the Best Art.’

John is an artist who sometimes draws dinosaurs and sometimes doesn’t.  John elected to argue that palaeoart has the potential to be a mainstream art movement. John provided a complete – and very entertaining – art history lesson taking us from the beginnings of fine art right up to the modern day, arguing that art has already done everything from realism to abstraction so what is left to be done? Can palaeoart be fine art? Is palaeoart impeded by being representational?  Palaeontology provides a new subject for art. Yes, it is technical, but that’s not novel. Art has been technical, fantastical, realistic and everything palaeoart is.  So why hasn’t palaeoart become mainstream? Is it because it’s never been pitched as art for its own sake? Palaeoart can inform and entertain. So what is stopping it from transitioning from the stuff of science at one extreme and of childrens’ playgrounds at the other?  John didn’t answer the question but left it as food for thought.  One thing was certain; the audience at tonight’s event would certainly be glad to see more palaeoart!

Following the presentations the audience was able to return to the art displays to appreciate with fresh eyes the palaeoart on display by the four artists, including items available for purchase. All the artists were open to questions about their art and about palaeontology and some very interesting discussions ensued, from the likely function of the hind paddles of a plesiosaur to which creature of highly limited fossil evidence would the artists most like to be able to understand and portray.

Thank you to the event hosts and organisers, King’s College London and Popularizing Palaeontology Workshop II, and the artists for putting on such an interesting and informative event.

Fossil Hunt at Isle of Sheppey, 12th Nov 2017

Posted on Updated on

20171112_121054

On Sunday 12th November UKAFH met in Warden, a small town on the Isle of Sheppey in Kent for the last UKAFH fossil hunt of the year.

Along the East coast of Sheppey is the largest exposure of London clay in the UK stretching over 6km from Warden to Minster on Sea. The London clay is a marine deposit roughly 52 million years old at this location, of the Eocene epoch. The fine sediment was deposited in a fairly deep, warm and placid sea which was relatively close to land – evident in the abundance of wood and plant remains and occasional but rarely terrestrial birds, mammals and reptiles.

After a fantastic explanation of the local geology and palaeontology by Sam Caethoven and a show and tell of some exceptional specimens by Eliott Mills, we were off in search of fossils!

We were bombarded by a strong, bitterly cold arctic wind but fortunately it was not long before we made some great finds. Lucy was first off the mark with a beautiful shark vertebra, found just a few hundred yards from the carpark. Gastropods, bivalves, nipa fruit and shark teeth were all found within a short time on the beach. We soon headed further north along the beach, staying clear of the tall clay cliffs which are particularly dangerous at the moment as large clay blocks are falling frequently – The site is prone to extreme erosion, most evident by the world war two pill boxes which once sat atop the cliffs but are now haphazardly strewn on the beach in front of us. Beyond the pill boxes, the great finds just kept coming. Numerous crab specimens in phosphatic nodules were collected, some of which were exquisitely well preserved. Shark teeth, ray teeth and fish vertebra were also abundant. Eliott Mills made the exceptionally rare discovery of a leaf preserved in clay.

The relentless biting winds made hunting tough, but we endured and were rewarded for our hardy nature. Thank you to everyone who attended, it was a great day and I hope you all thoroughly enjoyed yourselves!

See you all again in the New Year!!

UKAFH weekender at Folkestone and Samphire Hoe, Kent 14th and 15th October 2017

The Folkestone foreshore

On Saturday 14th October UKAFH took a group out to the Warren, Folkestone for day one of the Kent weekender.  We were blessed with unseasonably warm weather as our group of 30 descended the (pleasantly dry) mud footpath down to the beach to begin our hunt through the Cretaceous period! Once on the beach, UKAFH leader Chris Tait briefed the group on the geology of the location and what we might expect to find.

The rocks at Folkestone represent the Albian stage of the lower Cretaceous, 110-105 mya.  Lower Greensand is found at the base of the cliff with Lower and Upper Gault clay resting conformably atop, however the clay slumps over the Lower Greensand and is eroded at sea level to release large volumes of fossils onto the beach in this highly productive locality for fossil hunting.  During the time these sediments were laid down the UK was at a more southerly latitude in the area of the modern day Mediterranean and a warm sea teeming with life covered the UK.  During this time sea levels were transgressing, with the Lower Greensand being deposited as and continued to erode, to be replaced with fine clay sediments once nearby land was completely submerged.

The Lower Greensand is less fossiliferous as the near-shore environment it represents was less suitable as a habitat but still contains excellent fossils such as ammonites; the Gault Clay, however, is packed with diverse fossils, some with exceptional preservation. Ammonites, belemnites and molluscs are common; nautilus, crabs, crinoids, fish remains, shark teeth and scaphopods can be found, along with rare finds of reptilia. Examples of all of these were found by members of our hunt group!

Phosphatised preservation is typical but quality is variable, with examples often fragmented or in nodules.  However many examples are preserved in superb detail in pyrite and those which are newly emerged from the clay can retain some or all of their nacrous shell.  Bivalves and molluscs which are newly exposed are often extremely fragile and are rarely collectable unless carefully removed along with the surrounding clay, but ammonites are more durable and make marvellous specimens to add to a collection.

Soon after we reached the beach heading towards Copt Point the finds were already plentiful.  Partial regular and heteromorph (partially uncoiled) ammonites and bivalves were quite common and finds increased as people “got their eye in”. Some of the group progressed quite quickly along the beach to inspect the slips of clay for freshly washed out fossils and check out the shingle between the large rocks and boulders on the foreshore. Others remained nearer the start of the beach, working methodically through the shingle by hand, with a trowel, or dry sieving, in search of smaller finds like shark teeth.

Several members of the group found shark teeth, with Isabelle finding the largest example.  At the other end of the scale, Sam found a small but scarce Acrodus shark tooth while sieving using a 3mm mesh. Sieving is a good technique to remove sand and search for small fossils which wash out higher up the beach because they are lighter. Sieving and shingle-searching up the beach yielded crabs, solitary corals, urchin spines, shark teeth and vertebrae as well as fish teeth, a turtle bone and the day’s star find, a swordfish tooth!

By the end of the day we had a really great selection of finds amongst the group!

The following day we were greeted with yet another gloriously sunny autumn day, enhanced by the towering white cliffs of Dover above our meeting point as Samphire Hoe Country Park.  We had another full house of attendees and headed west along the beach to hunt for fossils amongst the chalk boulders on the foreshore.  Aidan Philpott, UKAFH Leader, explained the geology and identified local fossils to look for to the group. The lower chalk (also known as the grey chalk) at Samphire Hoe is from the Cenomanian stage of the Upper Cretaceous so yields fossils aged 100.5 – 93.9 Mya.

Common finds are brachiopods, bivalves and echinoids. Sponges, shark teeth, worm tubes, gastropods and fish can also be found and, rarely, ammonites. As well as beautifully preserved fossils within the chalk, some echinoids and shells and many sponges form flint casts which can be washed out of the chalk and found in the shingle.  Attractive pyrite crystals can also be found in the chalk.

Our first find of the lay was an eroded echinoid inside a flint block.  UKAFH leader Chris Tait then found a large section of clam.  These giant molluscs are mostly found broken into small pieces so this was a really nice find.  As the day progressed a good variety of finds were made including echinoids, shark teeth and brachipods.

Samphire Hoe isn’t the easiest location for fossil hunting as you need to scrutinise the loose chalk boulders on the foreshore carefully for signs of fossils and then extract them very carefully with a chisel to ensure they are not damaged.  You can also hammer the boulders to break the chalk up in search of fossils so work, tools and care are needed to have a good chance of finding fossils here.  Once extracted, however, preservation is usually excellent, with fine details clearly visible.

Cleaning chalk fossils is easy, requiring little more than dry brushing the remaining chalk matrix with a soft brush (a children’s toothbrush is ideal) to remove any chalk remaining on the fossil surface.  As chalk is very soft, you can easily remove larger amounts of remaining chalk with a blunt knife or craft knife until you approach the surface of the fossil and switch to brushing.

Finds were pleasing but not abundant, however everyone enjoyed the hunt and the sunshine day.

Chris, Aidan and Sam, your UKAFH leaders, would like to thank all of our members and attendees for joining us on our weekend fossil extravaganza and we look forward to seeing you all soon!

FOSSIL HUNTING EVENTS

 

 

Fossil Hunt at Seaford 1st October 2017

Posted on

20171001_113053

On Sunday 1st October, UKAFH ventured along the coastline of Seaford in East Sussex – a small town about 10 miles east of Brighton with towering white cliffs.

After a very fortunate summer meteorologically speaking, we had spent the week with a close eye on the remanence of hurricane Marie which crossed the Atlantic and now threatened our fossil hunt.

Fortune persisted however, as although a bit windy and the sea choppy, we began the day dry and mild.

We began with an in depth talk about the geology by UKAFH leader Daniel Slidel. Exposed in the towering white cliffs of Seaford is the Upper Chalk, a Cretaceous deposit (Santonian-Campanian) about 86-83 million years old. Formed from the tiny platelets of coccolithophores – phytoplankton that was abundant in the deep, warm sea that existed here. This striking sediment helped preserve the creatures dwelling on the sea floor, which included bivalves, sponges, corals, bryozoan and the echinoids (sea urchins) this stretch of coastline is famous for. Within the cliffs are horizontal bands of flints which are visible as far as the horizon allows.

After a short walk from the car park we descended some concrete steps onto the beach. The abundance of fossil echinoids was immediately noted as within the exposed bedrock on the foreshore were the tell-tale circular marks of weathered echinoids in situ. We could not extract these as the bedrock here is protected, however this gave us ambition as we traveled west towards loose boulders from which we could extract specimens. It was not long before beautiful echinoids were being found loose or extracted from boulders. There were two genre found, Echinocorys and Micraster. These were found in chalk boulders preserved with delicately thin calcite test – however the flints on the foreshore should not be overlooked either as more robust and often sea rolled specimens for found here too. Other finds on the day included small bivalves, shapely sponges, coral and bryozoan.

As the afternoon drew late the atmosphere became heavy with the approaching storm and the first rain fell as we ascended the concrete steps back to the car park. Looks like we did it again and avoided the worst of the weather!

Thank you to everyone who attended this fossil hunt. It really was a great and friendly group of people, it was a pleasure to guide you through the Cretaceous geological history of Seaford.

UKAFH visit Seatown, 10th September 2017

Posted on

On September the 10th, (which was a very blustery day) UKAFH set off on a hunt towards Golden Cap from Seatown.

In the right scouring conditions when the ledges are uncovered from the shingle, Seatown beach can be incredibly productive with the Belemnite Marls exposed – bringing out countless iron pyrite ammonites, crinoid stems and belemnites. Unfortunately, despite the gale that was blowing, the ledges remained covered.

We worked along the landslips on route to Golden Cap. The slips can produce green nodules (named because of the green calcite that makes up the preservation of the ammonites within). which contain many different ammonites, occasionally bivalves and very occasionally marine reptile remains. Within these nodule beds it is also possible to find parts of ammonites which have not been preserved within a nodule have been partially preserved. Many partially crushed Androgynoceras ammonites were found by members of the group, along with plenty of belemnites.

Once the group reached Golden Cap, we explored a little around the exposed Belemnite Marls and the landslips on the Seatown side (any further round, the wind became far too strong!). More belemnites and Androgynoceras ammonites were found. Despite the weather some great fossils were found!

Thanks to all who came along to Seatown and we hope you enjoyed the experience of

The new name of UKAFH

Posted on Updated on

We are pleased to announce we have changed the full title name of UKAFH. The new name “UK Association of Fossil Hunters’ works much better for the group than amateurs. We are always a family friendly group aimed at all levels, not just amateurs. We welcome beginners, and professionals too and of course amateurs will always remain closest to our group.

After much thought, we feel Association goes much better with who we are, and also retains our UKAFH abbreviated name!

So we welcome you to the UK Association of Fossil Hunters
