Chinese Fossils Return Home (Fossil Eggs in Time for Easter)

The National Geological Museum (Beijing) receives “Black Market” Fossils from Australia

A collection of rare fossil dinosaur eggs, fossilised dinosaur bones, fossils of ancient mammals, reptiles and Palaeozoic arthropods has been returned to China.  These items had been smuggled out of the country by dealers selling on the “Black Market”.  The haul was seized by Australian police officers in raids on several sites and offices in Western Australia.  This joint Chinese/Australian police effort to reduce the smuggling of Chinese fossils, has been in operation since 2004.

Fossils

This shipment of mixed Mesozoic and Palaeozoic specimens weighs more than 750 Kgs and would have fetched a small fortune for the smugglers had these artifacts found their way into the hands of private collectors.

This unusual contraband has been delivered to the National Geological Museum of China (based in Beijing).  Chinese scientists will be able to catalogue, study and preserve these rare finds helping to shed further light on prehistoric China.

Dinosaur Eggs

The collection includes 1,300 fossilised dinosaur eggs.  In the west, it is traditional to give eggs at Easter.  Nowadays, most of the eggs are chocolate, but I suspect the palaeontologists at the National Museum of China would much prefer to have these rare and delicate specimens returned to them than have chocolate Easter eggs.

The smuggling of fossils out of China is a big business, many rare and very valuable specimens are smuggled out of the country every year.  A law was passed in 2006 making all fossil finds state property in a bid to crack down on the smuggling rings. Despite the best efforts of the authorities smuggling is still common place especially in the more remote parts of China.

Frog Blog – We have Frogspawn in the Office Pond!

Frog Blog – We have Frogspawn in the Office Pond!

Four years ago whilst some of us were away in Canada working on some palaeontology projects, arrangements were made to build a small pond behind the office.  We had managed to persuade one of the designers of the animal enclosures from Chester Zoo to undertake the work and to produce a water feature with a seating area so that we could take our breaks and watch any wildlife that might be attracted to the water.

The work took about a week and our designer friend built two small ponds in a corner of the paved area behind the offices.  He even cleverly cast some ammonite fossils and installed these in various places in the rockery to make us palaeontologists and fossil collectors feel at home.

Using his expertise, our designer chum shaped the pond so that there would be plenty of shallow areas and margins, important when wanting to create a natural pond.  In addition, he advised on the planting and even provided the oxygenating water plants, the marginals and the lilies.  His final touch was to provide us with a population of snails to help maintain the pond.  We have two species at the moment a small pond snail and rams-horns (Planorbis sp.)

The Pond when it was First Built and Landscaped

Over the last few years this water feature has proved popular with the local birds who use the shallows as a bird bath and we have been fortunate to have damsel fly larvae as well as water boatmen take up residence.  Although, frogs had been seen in the vicinity and team members were able to count 3-4 individuals at anytime in the summer, (we even had a particularly large one that was nicknamed “Freddie” after Andrew Flintoff the England cricketer who took up residence in 2005);  no breeding had taken place.

However, this morning, whilst returning to the office to sort out some Everything Dinosaur paperwork, a quick check of the pond and hey presto – our first ever frogspawn was spotted.  There had been a number of frogs seen in the pond over the last month or so and apparently last night (a particularly dark and wet night) the spawning took place.

From the amount of spawn produced, we estimate that it is from just one female.  A total of four frogs have been observed in the pond this morning (the back of one can be seen partially hidden by the spawn to the right of the picture).  We have speculated that it is the female with her three suitors.  The frogs are Common Frogs (Rana temporaria), one of three species of frog that are found in the UK (excluding any escaped exotics).  Like all native British amphibians and reptiles they are a protected species.  With much of their habitat destroyed, areas such as landscaped offices and gardens are becoming increasingly important to them.

It is nice to know that after nearly 5 years the frogs have felt comfortable enough with our pond to breed in it, we are playing a small role in the conservation of this species and amphibians need all the help they can get, as they are globally the most endangered and threatened of all the animal classes.

Frogs are special to many of the Everything Dinosaur team members, they are very specialised Lissamphibians (the group of amphibians that includes frogs, toads, newts, salamanders and the leg-less caecilians).  The Lissamphibians were present in the Palaeozoic and it is thought that frogs evolved sometime in the Triassic,  however, the fossil record for frogs is very patchy to say the least.  They were probably relatively abundant during the Age of Reptiles, but the lack of fossil evidence inhibits palaeontologists when it comes to working out Anura (frog) evolution.  Fossil bones have been recorded from a number of Mesozoic sites but they are usually isolated fragments, ilia, humeri (limb bones) and the more robust skull elements.

Occasionally, fossils are found that demonstrate that some of these amphibians would have been formidable hunters, even capable of eating baby dinosaurs and young crocodilians.  The discovery of a giant frog from Mesozoic deposits in Madagascar is evidence of this.

Make Dinosaur Nests for Easter

By |2023-02-17T15:11:48+00:00March 15th, 2008|Educational Activities, Everything Dinosaur News and Updates, Main Page|0 Comments

Looking for something to do with your young dinosaur fans over the school holiday.  Here is a simple and fun recipe for dinosaur chocolate nests, an ideal activity for Easter time.  A super idea to help entertain the children, dinosaur chocolate nests for kids.

Dinosaur Chocolate Nests

Ingredients – (makes a batch of about 8 nests)

Plain or Milk cooking Chocolate 225 grammes (8oz)

Packet of Breakfast Cereal Cornflakes or Shredded Wheat variety

Packet of Sugar Coated Mini-chocolate Eggs

Pack of Small Cake Cases

Dinosaur Nests – a Great Holiday Baking Activity

Picture Credit: Everything Dinosaur

Method

1.  Break the cooking chocolate into pieces and place in a heat-proof bowl.  Melt the chocolate over a pan of simmering water.

2.  Once the chocolate has melted remove it from the heat and give it a good stir in the bowl.

3.  Add some of the breakfast cereal until the mixture takes on a a brown twiggy look.

4.  Carefully spoon enough of the mix into each paper case so that a little nest is formed.  Make sure you push it down in the middle so that each nest has a hollow in the centre

5.  Place two chocolate mini-eggs in the centre of each chocolate nest, the eggs will stick when the chocolate sets. Two eggs is all you need for each nest (we know that some dinosaurs laid eggs in pairs so your chocolate nests would please a palaeontologist) – see notes below.

6.  Then leave the nests to set.

There you are a set of lovely dinosaur themed nests, an ideal activity for young palaeontologists over the Easter break.

For other baking ideas, recipes and for fun party items visit the section of the Everything Dinosaur website that deals with parties: Dinosaur Toys and Gifts.

Dinosaurs and their Nests (a little bit of science)

Many nests of dinosaurs have been discovered, particularly over the last fifteen years or so with the discovery of sauropod nesting sites in Argentina and Europe plus more evidence having been gathered from places such as the famous Flaming Cliffs area of Mongolia.

The first dinosaur eggs were discovered in 1859 (France). The first recognised dinosaur nests were uncovered by an American team of palaeontologists led by Roy Chapman Andrews during expeditions to Mongolia in the 1920s.  Over the last few years, scientists have been able to build up their knowledge about dinosaur reproduction and egg laying as egg-shell fragments, nests, and even fossils of unhatched baby dinosaurs inside eggs have been discovered.

The pairs of eggs laid in our pretend chocolate nests are based on the layout of eggs found in theropod dinosaur nests.  Many theropod nests (tyrannosaurs, allosaurs, Velociraptors, Oviraptors were theropods); consist of a dug out, roughly bowl shaped hole with pairs of eggs laid are in a circle, pushed into the earth and they are laid in pairs.

Dinosaur Eggs

The laying of eggs in pairs seems to be a unique characteristic of theropod dinosaurs.  No other group of animals either around today or found in the fossil record laid eggs in pairs.  Theropod eggs tend not to be very round, they are rounded at one end with a more pointed end opposite, a little like a loaf of French bread.  The more pointed end is often found buried in the rock which comprises of the fossil, this indicates that the female theropod that laid the eggs, pushed it into the dirt during the process of laying.  This is evidence of dinosaurs showing a delicate touch, in the same way that a crocodile cradles newly hatched baby crocodiles in her mouth in readiness to carrying them down to the nursery pool.

The eggs laid in pairs indicate that dinosaurs had two oviducts (the tube in female egg-laying animals where eggs are formed and through which they are laid).  The position of fossilised pairs of eggs in theropod nests indicate that eggs were laid from the two oviducts at the same time. This would be the equivalent of a double-barrelled shot gun firing both barrels at once.  This behaviour seems unique to theropods.  Crocodiles have two oviducts but they do not demonstrate egg laying in pairs.  Birds, (believed to be close relatives of theropod dinosaurs), only have one functioning oviduct and only one egg is formed by day.  Birds can take several days to lay a clutch of eggs.

Scientists believe that birds evolved only one functioning oviduct and the laying of eggs over a protracted period in order to help them escape from predators.  After all, it would be difficult to fly if a female had a clutch of six or seven heavy eggs inside her ready to be laid.

Other scientists have speculated that the laying of eggs over several days may help the pair bond and this may reinforce behaviour towards brooding and feeding the youngsters as they hatch.  Yet another theory is that with a delay in laying, comes a delay in the time of hatching, some birds end up with a nest full of offspring, but at slightly different ages.  If food becomes scarce then the older siblings can out compete the younger ones and these are the ones that will survive to reach the fledgling stage.

Palaeontologists have a lot to learn about dinosaurs and the egg laying habits, however whilst you contemplate these important aspects of dinosaur behaviour and social habit you can tuck into your own dinosaur nest as a treat.  Help yourself to Everything Dinosaur’s chocolate dinosaur nest recipe.

Triceratops for Sale

By |2023-02-17T15:09:14+00:00March 13th, 2008|Dinosaur and Prehistoric Animal News Stories, Dinosaur Fans, Main Page|0 Comments

Triceratops Available to the Highest Bidder – Three-horned Face up for Auction

An almost complete fossil Triceratops, perhaps one of the best known of all the dinosaurs, is going under the hammer at Christie’s; the auction house in Paris next month.  There is a Triceratops for sale at an auction house.

The almost 70% complete fossil is the prize lot in an auction of 150 rare items from natural history collections – fossils, skeletons and minerals expected to fetch in excess of £1.225 million GBP (1.6 million EUR).

As well as the three-horned dinosaur, there will be opportunities to purchase a Sabre-toothed cat skull, a tyrannosaur egg, plus the tibia (shinbone) of an Apatosaurus.  Although it is difficult to put a reserve on such unique and rare items; the egg is expected to fetch over £15,000 GBP (20,000 EUR) and the sauropod tibia around £23,000 (30,000 EUR).

The Triceratops is certainly the star attraction, the fossil is almost 70% complete, the missing bones having been replaced by resin replicas to provide an articulated and posed exhibit.  It will be the first time a dinosaur specimen has gone up for public sale since the Tyrannosaurus rex called Sue was auctioned at Sotheby’s in New York on October 27th 1997.  Sue, an almost complete T. rex fetched $8.36 million USD, it is unlikely bidding for this Triceratops will reach those dizzy heights, but if you want a three-horned face for your living room or hall expect to pay about £380,000 GBP (500,000 EUR) for the privilege.

Triceratops for Sale

Triceratops is perhaps the most famous of the horned dinosaurs.  It gets its name from the three forward facing horns on its face, approximately 60 skulls have been excavated plus a number of disarticulated specimens.  Finding a complete fossilised Triceratops is an exceptionally rare event.  The skull of an adult Triceratops is over 3 metres in length, it would have been exceptionally heavy and as there was not a great deal of meat on it, this part of the Triceratops was often left alone by Tyrannosaurus rex which predated on these animals.  The robust nature of the skull favoured preservation so there is a reasonable amount of fossilised skull material in the fossil record.  However, the rest of the animal has proved to be much more difficult for palaeontologists to find.

If a Triceratops had been killed by a meat-eater the carcase would have been broken up and eaten.  What remained would have been soon scavenged so little would remain available for transport and preservation as fossils.  Even if a Triceratops died of natural causes the body would still have been attacked by hungry scavengers, quick to seize the opportunity of an easy meal.

The Herding and Social Behaviour of Triceratops

The herding and social behaviour of Triceratops also seems to have counted against it when it comes to fossilisation potential.  Unlike other ceratopsians, Triceratops seems to have moved around in relatively small groups, so there is less likely to find a mass bone-bed with Triceratops than with other slightly earlier horned dinosaurs such as Centrosaurus.

Some scientists claim that there may be up to ten different species of Triceratops.  Subtle differences in skull morphology may indicate separate species, although these differences may be due to ontogeny and sexual dimorphism (skull shapes change as animals age and there may be difference between males and females of the same species).  The species represented in the auction exhibit is T. horridus, the largest recognised species of Triceratops.  Triceratops horridus means “horrible horned face” , but hopefully this name will not put off any bidders.

It certainly is a large specimen with an overall length of 7.5 metres and a total fossil weight of approximately 2 Tonnes – very impressive; but a full size T. horridus would have exceeded 9 metres in length and some scientists estimate a body weight of around 10,000 KGs (that is the equivalent of two African elephants).

The fossil skeleton was originally found by a ranch owner in the US state of North Dakota and acquired in 2004 by a European buyer who wants to remain anonymous, said a Christie’s spokesman.

“This specimen is the fourth most complete discovered so far,” he went on to state.

For many years scientists debated how Triceratops might have walked.  Two schools of thought emerged, one school believed that Triceratops moved its front legs like a lizard in a more sprawling type gait.  The second group of scientists believed that Triceratops walked with its elbows tucked in under the body, like a modern Rhinoceros.  To substantiate which theory was most likely to be correct the palaeontologists needed one crucial piece of evidence – an articulated Triceratops with the feet in situ.

Unfortunately, tyrannosaurs and other meat-eaters tend to leave only scraps.  When ever fossils of Triceratops were found the feet were almost never located.  Perhaps the feet of Triceratops were especially tasty for a tyrannosaur, a delicacy almost, like chicken feet are a delicacy in some parts of Asia.  More likely, the large amount of meat on this part of the animal would have made the bones attractive and although large, many predators at the time were capable of picking up and moving Triceratops limbs away from the rest of the carcase to consume without the danger of the body attracting other hungry mouths to threaten them.

Not so long ago a partially articulated fossil Triceratops was discovered.  The whole of the left side of the carcase had been washed away but the right side was almost complete and most importantly of all, the feet remained.  It was hoped that this specimen (nick-named Raymond), would solve the mystery of how Triceratops walked once and for all.  Unfortunately, the bones had been rather flattened and squashed during preservation so the fossil evidence could in effect, be interpreted and presented in such a way to support both theories.  Scientists seemed to be no nearer understanding whether this four-legged leviathan walked like a lizard or in a more erect pose like a rhino.

Thankfully, the discovery of some beautifully preserved fossilised Triceratops ribs and other body parts including shoulder blades helped shed some further light onto this mystery.  Scientists were able to see how the front legs would have moved in relation to the shoulder blade sockets.  The result, led some scientists to conclude that Triceratops had a semi-erect posture, somewhere between walking with a sprawling gait like a lizard and the elbows tucked underneath walking style of a Rhinoceros.

The model shown is from the Schleich Dinosaur series, it depicts Triceratops with a semi-erect stance with the hind legs, bowed out a bit to make room for the animal’s enormous gut.

The bright colours shown on this particular model is following a trend amongst palaeontologists to illustrate herding dinosaurs with stark, contrasting colours.  It is believed that Triceratops had excellent colour vision and it may have used body patterns to communicate with other members of the herd, show dominance, social status and such like.

Prices for dinosaur fossils have reached record levels in recent years.  They have become the “must haves” of the rich and famous, so this has led to the removal of many important finds out of scientific circles and into private collections.

Even movie stars have started collecting dinosaurs, to read an article on celebrities arguing over tyrannosaurs: Dinosaur Bidding Wars – Celebrities push up prices of Dinosaur Fossils.

Two-Toed Footprint found in Korea – Dromaeosaurs in Korea

By |2023-02-17T15:10:28+00:00March 12th, 2008|Dinosaur and Prehistoric Animal News Stories, Main Page|6 Comments

Two-Toed Footprint – Evidence that Dromaeosaurs stalked Ancient Korea

Reports have been circulated that a researcher from the Korean National University of Education has discovered a two-toed dinosaur footprint.  Only one family of dinosaurs is known to have made two-toed prints, the bipedal dromaeosaurs (the family is Dromaeosauridae means “swift lizards”).  Members of the Dromaeosauridae include animals such as Velociraptor, Deinonychus and Utahraptor.  A trace fossil such as a two-toed print is indicative of a dromaeosaur.  These animals did have three toes that reached the ground, but the claw on the second toe was raised when it walked, keeping it sharp and pointed.  This was the infamous “sickle claw”.  Hence when these animals walked or ran, only two-toed prints were left behind.

Everything Dinosaur stocks the popular Beasts of the Mesozoic range of dromaeosaurid models.  To view this range of articulated dinosaur figures: Beasts of the Mesozoic Models and Figures.

From South Gyeongsang Province

This trace fossil was found in South Gyeongsang Province.  It is relatively small when compared to other theropod footprints, measuring 15.5 cm in length with a width of 8.4 cm, but this is a significant find as dromaeosaur trackways, like most meat-eater trackways are very rare when compared to the tracks made by herbivores. This phenomenon is due to the fact that there are more prey animals around at any one time than predators.  This is the first evidence of dromaeosaurs in Korea, the strata in which the print was found has been dated to 100 million years ago.

Dromaeosaurs in South Korea

This print proves that there were small “raptor-like” dinosaurs in Korea during the Cretaceous.

Recently, a dromaeosaur trackway was unearthed in China, it may indicate social, pack behaviour.  To read more about this discovery:

Prehistoric Animals Captured on Film!

Cryptozoologists spend years researching, seeking information and piecing together evidence in support of claims that mythological creatures or supposedly long extinct animals still wander around the planet.  There have been many reported sightings of sea and lake monsters; could these be plesiosaurs perhaps?  Sir Arthur C. Clarke commented on the authenticity of Woolly Mammoth sightings reported in the 17th century in his book based on the ITV television series “Arthur C. Clarke’s Mysterious World”.

Prehistoric Animals

A number of popular myths concerning dinosaurs still being around persist, the most famous is perhaps the long-necked, sauropod-like Mokele-Mbembe that lurks in the deepest, darkest parts of the Congo.  How a forested and flooded area less than 2 million years old is supposedly harbouring a population of Sauropods, remnants from the Mesozoic is not easy to explain, but so long as such inaccessible and relatively unexplored places exist then these stories and myths will continue.

Photographing Prehistoric Animals

For team members at Everything Dinosaur, photographing prehistoric animals is made a lot easier.  For us, having the opportunity to photograph prehistoric animals does not entail long treks into far off and distant lands.  However, it does mean a trip to Wales, to a small town called Cefn Mawr, where we met up with Michael, a professional photographer, who had been given the task of helping us create some images of our new products.

Michael is a member of the Master Photographers Association, and all of his twenty plus years experience as a professional photographer was applied to the task of creating shots of our new dinosaur themed tableware, biscuit making moulds, new T-shirts, books and models.  There was even a requirement to photograph some dinosaur teeth!

Into the Studio

Using Michael’s own well equipped studio, our team, working under Michael’s supervision were able to complete the photography in a morning.  Starting with the small, intricate shots of new models and working up to the bigger products such as the beach set inflatables.  The final few pics involved an Everything Dinosaur team member, pictures being taken in preparation for a forthcoming press release.

Taking a short break from preparing a Polacanthus and helping to compose a Cryolophosaurus we were able to relax in the very comfortable office that adjoins the studio and admire the results of some of the more routine photographic assignments.  The walls display a range of different types of photography from splendid wedding shots to intimate family portraits and touching shots of new babies with their proud parents.

Certainly, our brief to photograph a range of prehistoric animal themed items is a little out of the ordinary, but Michael and his partner take it all in their stride.

The picture shows Michael, shooting the “Ice Age” Mammals from the Natural History Museum box set, just one of the unusual subjects that he was asked to photograph during the day.

To view the prehistoric animal box set: Dinosaur Toys and Prehistoric Animal Models.

For a number of shots, close ups were required; it is a good job the studio floor is cushioned and sprung as Michael spent most of the morning on his knees, taking care to ensure each new product could be shown at its best.  The final images will be well worth all the effort, and will help us to show customers the products that we supply in our shop.

As for Michael, with a background in commercial photography, PR shoots as well as family portraits and weddings it was all in a morning’s work.

An Update on Those Long-Limbed Tyrannosaurs

By |2023-02-24T17:56:33+00:00March 10th, 2008|Dinosaur Fans|0 Comments

Looking at the North Laramidian Tyrannosaur Albertosaurus

Despite their frequent appearance in monster movies the Tyrannosauridae are perhaps not as well known as many people might think, especially when they are faced with the overwhelming number of tyrannosaur exhibits on display at Natural History museums.  Expect the BBC and 20th Century Fox to portray a member of the tyrannosaurid family as the villain in a forthcoming film.  The reality is, even the mighty Tyrannosaurus rex has provided less than forty fossil specimens for palaeontologists to study and the vast majority of these are far from complete.  The popularity of these fierce carnivores is easy to understand, they were certainly impressive beasts but scientists still have a great deal to learn about these animals, their ancestry, social behaviour and morphology.

Long-limbed Tyrannosaurs

The likes of Tyrannosaurus rex is synonymous with the Hell Creek Formation of Montana in the north-western United States.  The exposed strata  of sandstone, siltstone and mudstone represent sediment laid down towards the very end of the Cretaceous (Maastrichtian faunal stage).  It was from these beds that the first T. rex fossils were unearthed.  However, a greater number of Tyrannosauridae fossils have been recovered from Canada, specifically areas such as the Dinosaur Provincial Park Formation in Alberta.

The extensive outcrops of Campanian faunal stage strata from deposits termed the Belly River Group and the Judith River Formation have been dated to approximately seventy-five  million years ago.  The theropod fossils recovered from these sites along with other body and trace fossils have enabled palaeontologists to build up a detailed picture of the eco-system that existed in this area at the end of the Cretaceous.  This has led to some speculation as to the hunting habits and specialisation of the tyrannosaurs in this faunal community.

The Albertosaurinae and the Tyrannosaurinae

Late Cretaceous tyrannosaurids of Alberta can be grouped into two sub-families, the Albertosaurinae and the Tyrannosaurinae (work from Phil Currie et al).  The albertosaurines from the Dinosaur Provincial Park can be split into two genera, Albertosaurus and Gorgosaurus), the Tyrannosaurinae are represented by Daspletosaurus.  In the 1970s the genus Gorgosaurus was dropped and it was synonymised with Albertosaurus, following a review of existing specimens where no significant characteristics were identified, permitting both genera to be valid.  This viewpoint was overturned in 2003 when following a study by a Canadian led team looking at fossils recovered after the review in the early 1970s, a number of differences were identified between Gorgosaurus and Albertosaurus and so both taxa were validated.

Gorgosaurus was reinstated.

The Death Pose of a Canadian Tyrannosaur (Albertosaurus)

The “Death Pose” of a Dinosaur.

Picture credit: Everything Dinosaur

The picture shows an almost complete and articulated restoration of an Albertosaurus specimen on display at the Royal Tyrrell museum (Canada).  The neck and head presented in a curved position over the back and hips is typical of articulated Dinosauria fossils, this effect is believed to occur as ligaments and tendons are desiccated in the carcase and their drying out leads to the head and neck curving over the back of the animal.

Different Hunting Strategies

The albertosaurs shared their Late Cretaceous world with the likes of Daspletosaurus, (Daspletosaurus means “frightful lizard”).  Both these types of tyrannosaur were predators and likely to have been at the top of the food chain, however, examination of their fossils reveals that they may have specialised in different hunting strategies and prey.

Albertosaurs had slightly shorter, lower skulls than many other tyrannosaurs.  Their leg bones, especially the tibia (shin bone) were proportionately longer than equivalent sized tyrannosaurs.  They had longer toes and although the weight of an adult Albertosaurus (A. sarcophagus), has been estimated at 2,500 kilograms, these animals were lighter than equivalent sized Tyrannosaurinae.

In recent years, scientists have concluded that there were two distinct clades of tyrannosaur in North America during the Late Cretaceous inhabiting the land mass known as Laramidia.  The first clade, from the north (Canada) featured long-snouted forms such as Albertosaurus.  The southern Laramidia group, the group that was to give rise to the most famous tyrannosaur of them all – T. rex (Utah, Montana, Wyoming etc). had more square, broader, box-like skulls.  Scientists remain uncertain how these distinctions evolved.

Everything Dinosaur stocks a wide range of tyrannosaur models including several North American genera. To view the extensive range of dinosaur models in stock: Tyrannosaur and Other Dinosaur Models.

In Memory of Pioneering Mary – Mary Anning who died on this day in 1847

By |2024-04-12T08:25:20+01:00March 9th, 2008|Famous Figures, Main Page, Palaeontological articles|0 Comments

In Memory of Mary – Mary Anning (May 21st 1799 to March 9th 1847)

A breakthrough in our understanding of the world around us – a eureka moment in science is a rare thing.  More often than not scientific progress is made in small steps with scientists and researchers building upon the insights and work of others.  Palaeontology like other sciences is no exception, after all, science is driven forward by ignorance, our desire to turn what we don’t know into what we do know.

Our thoughts today turn to Mary Anning, who died on this day in 1847.  Mary was born on May 21st, 1799 in the town of Lyme Regis, Dorset.  Her father was a carpenter.  Although she had no formal education to speak of and she spent most of her life in poverty, Mary was a pioneer in the sciences of geology and palaeontology, her contribution to science is recognised throughout the world and she is one of only two scientists permitted to have a look-a-like walking the hallowed galleries of the Natural History museum in London.

Mary Anning

Mary is credited with the discovery of many ichthyosaurs, plesiosaurs and the first pterodactyl fossils (pterosaurs).  Most of the fossils Mary collected were sold to institutions and private collections, but often no record was kept of her role in discoveries and scientific research.

Although she lacked a substantial formal education, she taught herself anatomy, animal morphology and scientific illustration.  She made an immense contribution to the nascent sciences of palaeontology and geology, but much of her work was plagiarised and she was not given the recognition she deserved in her lifetime.  As a woman and with a poor social status she was never accepted into the male dominated scientific community.

Towards the end of her life it was rumoured that Mary had taken to drink.  Perhaps this was as a result of her struggle for recognition gradually wearing her down, but more likely Mary was drinking to dull the pain of breast cancer.  In the mid 19th century, one of the few pain killers that could be afforded by the poor was alcohol.  Although, weak and very ill, Mary continued to sell her “curiosities” from her fossil depot in Lyme Regis

News of her illness reached members of the Geological Society in London, William Buckland, the Dean of Westminster used his influence to raise a fund to help support her, but there was little he could do to prevent the inevitable outcome.  She died in 1847, just a few weeks before her 48th birthday.

Mary is buried in the little Lyme Regis churchyard, part of which overlooks the bay.  I am sure Mary would have appreciated this, as it was in the bay overlooked by the church that Mary earned her living searching for fossils amongst the land slips and mud slides of the cliffs.

The then President of the Geological Society – Henry de la Beche wrote a eulogy in her honour, a most unusual tribute as she was not a Fellow.

He wrote: “I cannot close this notice of our losses by death without adverting to that of one, who though not placed among even the easier classes of society, but who had to earn her daily bread by her labour, yet contributed by her talents and her untiring researches, in no small degree to our knowledge of the great Enalio-Saurians and other forms of gigantic life entombed in the vicinity of Lyme Regis.

Fellows raised funds for a stained-glass window in her honour at the parish church at Lyme Regis. The window depicts Mary tending the sick and looking after the poor, an inscription underneath reads: “In commemoration of her usefulness in furthering the science of geology, as also of her benevolence of heart and integrity of life”.

Perhaps the last word for now, about Mary should come from a reporter who wrote in a journal published at the time – “the carpenter’s daughter has won a name for herself, and deserved to win it”.

Good on you Mary, we will always remember.
