Researchers Report on Cretaceous Trace Fossils From Angola

Important Prehistoric Animal Tracks Discovered in Angola

Amongst the many exciting news stories that have come out of the annual Society of Vertebrate Palaeontology meeting held this week in Berlin, is the report from the Paleo Angola Project about the discovery of extensive vertebrate tracks preserved in sediment that now makes up part of a diamond mine in north-eastern Angola.

Angola is one of the new frontiers for palaeontology.  This vast, yet underdeveloped country in southern Africa is believed to contain a number of Mesozoic aged, highly fossiliferous deposits and it is likely that any dinosaur fossils excavated from this country are likely to be species new to science.

In a report to the Society of Vertebrate Palaeontology, researchers from the Paleo Angola Project described a location in the silt and sand deposits that represents a lacustrine (lake) environment dating from approximately 118 million years ago (Aptian faunal stage).  Approximately, seventy distinct footprints have been identifed so far.  These trace fossils represent footprints made by Sauropod dinosaurs, crocodiles and a relatively large prehistoric mammal.  The mammal print is particularly intriguing.  Most mammals during this part of the Cretaceous were very small, no bigger than rats, but the five-toed print measuring more than three centimetres across indicates that a mammal the size of a Bedlington Terrior dog or a North American Raccoon.  The scientists stated that the tracks were probably made over a substantial period of time, as the lake dried out over several seasons.

The mammalian track suggests that in at least this part of Africa, mammals were much larger than previously thought.  The mammal track has been described as “a very rare find.”

Working out what kind of mammal left the rare footprints may not be possible, after all, no body fossils have been found.

Commenting on the discovery, Marco Marzola, one of the palaeontologists with the Paleo Angola Project explained:

“We cannot narrow down to a species but we can say what they [the footprints] do belong to.  They were made by an exceptionally large mammal, that we can say for sure.”

In the same location, eighteen Sauropod tracks have been discovered, the Paleo Angola Project team have already named and described one giant, long-necked dinosaur that once roamed Angola.  The fossils of this dinosaur were found in marine sediments.  It is likely that the corpse floated out to sea and there is evidence preserved on the fossilised bones of feeding from sharks, that were scavenging the carcase.

Praising the action of the consortium which owns the diamond mine (Catoca mine, the fourth largest diamond mine in the world), the scientists said that the mine owners stopped all activity at the mine to allow the researchers to map and plot the trace fossils.  The mine owners put the promotion of vertebrate palaeontology in Angola ahead of their own desire to make money.

Ankylosaurs with Air Conditioning

Complicated Nasal Passages Helped Keep Ankylosaurs Cool

Animals have a number of ways of controlling their body temperatures and cooling down.  Some warm-blooded animals like kangaroos and antelopes seek shade during the heat of the day.  Elephants cover themselves with mud or take a cooling dip.  Dogs pant and humans sweat, but how did the heavily armoured dinosaurs keep cool?  These “living tanks” with their huge, armoured bodies could have been in danger of overheating as they wandered around in the Mesozoic.  A new paper suggests that their complicated nasal passages not only would have helped these animals with their sense of smell, but they would have acted as very efficient heat transfers.

A team of scientists based at Ohio University used CAT scans of ankylosaurid cranial material to map the anatomy of the complex nasal passages in two different North American Ankylosaur species.  The team then modelled the air flow in three dimensions using a computer programme that interpreted the CAT scan data.  Palaeontologist Jason Bourke, one of the authors of the scientific paper stated that the complex nasal passages would have given the inhaled air more time to warm up to body temperature by drawing heat way from blood vessels in the nasal cavity.  This would have helped cool the blood and in turn this would have cooled vital organs such as the brain.  The brain of even the largest ankylosaurids was extremely small when compared to their body size.  The dinosaur experts at Everything Dinosaur regularly compare the brain of a large Ankylosaur such as Euoplocephalus tutus to the size of a child’s fist.  The nasal passages would have helped to keep the brain in its heavily armoured skull cool and stable.

Mammals and birds use scroll-shaped bones called conchae, otherwise known as turbinates to warm air that is breathed in, but the armoured dinosaurs seem to have achieved the same result with a completely different anatomical configuration.

Commenting on the study, Jason Bourke stated:

“There are two ways that animal noses transfer heat while breathing.  One is to pack a bunch of conchae into the air field, like most mammals and birds do, it is spatially efficient.  The other option is to what lizards and crocodiles do and simply make the nasal airway much longer.  Ankylosaurs seem to have taken this second approach to the extreme.”

Doctor Lawrence Witmer (Ohio University), who was also involved in this research explained:

“Our team discovered these “crazy-straw” airways several years ago, but only recently have we been able to scientifically test hypotheses on how they functioned.  By simulating airflow through these noses, we found that these stretched airways were effective heat exchangers.  They would have allowed these multi-tonne beasts to keep their multi-ounce brains from overheating.”

Ohio University researchers had previously studied the complex nasal passages of another group of Ornithischian dinosaurs – the Pachycephalosaurs.

To read this earlier article: Nosing Around Pachycephalosaurs

Just like noses in humans, (Homo sapiens) ankylosaurid noses are likely to have served more than one function.  As the complex nasal passages helped condition the air that was breathed in and out, water may have been removed from exhaled breath helping these dinosaurs to retain water, important when you live in arid environments.  In addition, the convoluted passageways may have added resonance to the low-pitched sounds this dinosaur made.  The nose could have amplified these sounds acting as a resonator, making the noises made by Ankylosaurs  heard over greater distances.

New Collecta Models (Part 2)

New Releases from Collecta for 2015 and Model Measurements

Those clever people at Collecta have released the second batch of new additions to their “Prehistoric Life” model series.  These are all models that will be stocked by Everything Dinosaur in 2016.  In this short article, we provide pictures of the new models and update readers on the dimensions of all the 2015 releases to date.

So let’s jump straight in..

Collecta Smilodon Replica (May 2015)

This is a very well designed model of a Sabre-Tooth Cat.  The replica measures a little under 13cm in length and the head stands around 8cm high.  The model is in the not-to-scale range and Everything Dinosaur believes it is a replacement for the earlier Smilodon model introduced a few years ago.  This earlier Smilodon is likely to become a rare model so Everything Dinosaur urges collectors to acquire this replica before it is officially retired.

To view the existing Collecta Smilodon model: Ice Age Toys and Models

Let’s retain the prehistoric mammal model theme and discuss the entelodont replica, the 1:20 scale model of Daeodon.  This model will also be available from Everything Dinosaur in the late spring of 2015.

1:20 Scale Deluxe Daeodon Entelodont Model from Collecta

This beautifully painted model of a “war pig” as we like to call it measures a fraction under 16cm in length and the height of the hump is 9.5cm off the ground.

Sticking with the Deluxe range, another new addition, in what will be termed the Supreme Deluxe range and available from Everything Dinosaur in the late spring of 2015 is this excellent model of the Pterosaur called Guidraco.  This is in approximate 1:4 scale and the model measures 25cm long and it stands approximately 25cm high.  This replica will have an articulated lower jaw. The colour scheme has been based on an Atlantic Puffin (Fratercula arctica), one of our favourite sea birds.  Guidraco (fossils from the famous Lioaning Province of China), like the Puffin, was believed to be a fish-eater.

Last week, Everything Dinosaur team members posted up images and further information on the first of the 2015 model releases from Collecta.  To view this article: First Pictures of New Collecta Model Releases

Here are the measurements of the models we featured:

  • Xiongguanlong – this Cretaceous tyrannosaurid model measures 10cm long with a head height of around 6cm
  • Nasutoceratops – a beautiful horned dinosaur model which measures 13cm long with a head height of 6cm
  • Medusaceratops – a slightly larger horned dinosaur model which is 14.5cm in length with a head height of around 7.5cm
  • Daxiatitan – a model of a huge, Chinese Titanosaur which measures over 29cm long with a head height of a fraction under 21cm

This model measures 31cm in length and that bulky body stands around 6cm high.  The replica is based on a Dorset fossil specimen, a spectacular Pliosaur known as P. kevani which is known from a two metre long skull and jaw currently on display at the Dorset County Museum.  This Pliosaurus has Sea Lampreys attached to it. Although, we at Everything Dinosaur, are not aware of any fossil evidence to suggest Lampreys attaching themselves to marine reptiles, since a number of Sea Lampreys feed on Cetaceans in coastal waters today, it is likely that these ancient, jawless fish fed on the giant marine reptiles of the past.

Year 2 Pupils Learn All About Dinosaurs

Dinosaur Workshop at Liverpool Primary School

School children at Anfield Infants School enjoyed a visit from Everything Dinosaur this week, as Year two pupils studied dinosaurs and fossils.  The school children had just started their topic and they had lots of amazing questions about prehistoric animals, which we did our best to answer.  The dedicated teaching team had prepared a comprehensive scheme of work and they had posted up a huge K-W-L chart in each of the Year 2 classrooms (high flyers, bright sparks and whizz kids).

The K-W-L Chart Prepared as Part of the Term Topic

The K-W-L concept helps teachers to plan a topic and to check learning.  It consists of three areas, firstly, the children brainstorm and say what they think they know about dinosaurs and fossils.  During the brainstorming session, statements might be identified that provide the teacher with information as to what the children would like to find out about prehistoric animals.  The third area highlights what the children have learned at the end of the topic.  This helps reinforce learning and allows the teacher to check understanding.

The Everything Dinosaur team member, as part of the dinosaur workshop, challenged the classes to carry out some extension activities and promised to follow up any questions that the children emailed into the company as part of uniting this topic with their ICT studies.

Lots of Prehistoric Animal Inspired Artwork on Display Throughout the School

Egg Shape Could Explain Survival of Birds into the Cenozoic

New Study Suggests Egg Shape Might Hint at Clues to Survival

Eggs come in many different shapes and sizes.  There are large ones, small ones, those that are more rounded, others that can be more ovoid in shape and so on.  However, a new study, conducted by evolutionary biologists at Lincoln University (UK), suggests that egg shape could have been a factor in why some birds survived the Cretaceous extinction event, whilst other types of bird and the Dinosauria did not.  The research published in the on line journal of the Royal Society, looks at the geometry of eggshells and highlights morphological differences between the eggs of birds and those of their extinct, but very close relatives, the Theropod dinosaurs.

Birds, Reptiles and Mammals are linked as all these types of creature are descended from Carboniferous Tetrapods that evolved an ability to reproduce from an egg that was contained within a semi-permeable eggshell.  These early terrestrial animals were no longer dependent on the presence of water in order to breed and reproduce successfully.  These types of eggs are called Amniotic eggs.

Safe from drying out, the embryo inside the egg is further protected by a robust, internal membrane called the Amnion.  It is the evolution of the Amniote egg that permitted Tetrapods to conquer all terrestrial environments.

In this new study, the research team noted that there were notable differences between the eggs of birds that survived the Cretaceous mass extinction event that took place around sixty-five million years ago, and the shape of the eggs of those creatures that become extinct.  Although, the fossil record is far from complete when it comes to preserving evidence of eggs and reproductive strategies, the results suggest that early birds from the Mesozoic laid eggs that had different shapes to those of modern birds.  It is possible that egg morphology indicates different physiologies or different rates of embryonic development and this may have implications when it comes to surviving a mass extinction event, such as that which led to demise of around 70% of all terrestrial life, including all the non-avian dinosaurs.

Could Theropod Egg Shape Have Doomed the Dinosauria?

One of the authors of this new paper, Dr. Charles Deeming (School of Life Sciences, Lincoln University) explained:

“These results indicate that egg shape can be used to distinguish between different types of egg-laying vertebrates.  More importantly they suggest Mesozoic bird eggs differ significantly from modern day bird eggs, but more recently extinct Cenozoic birds do not.  This suggests that the range of egg shapes in modern birds had already been attained in the Cenozoic.”

As extant Amniotic eggs vary considerably in size and shape and this variety reflects different patterns of egg formation and development, then the variation seen in the fossil record of eggs may also reflect different patterns of egg formation, egg development and even nesting behaviour.

Dr. Deeming commented:

“From a biological perspective, it is self-evident that different egg shapes by birds, both past and present, might be associated with different nesting behaviours or incubation methods.  However, hardly any research has been carried out on this topic and fossil data are insufficient to draw firm conclusions.  We hope that future discoveries of associated fossil eggs and skeletons will help refine the general conclusions of this work.”

Although there might be a link between eggshell shape and the ability to survive the Cretaceous mass extinction, it is likely that a lot of other factors contributed to the survival of one group of vertebrates whilst others died out.  The eggshell shape itself may be a part of the story, but palaeontologists are confident that dinosaurs, including many Theropod dinosaurs engaged in complex nesting behaviours, brooded eggs on nests and invested a great deal of time and effort in raising the next generation.

A spokesperson from Everything Dinosaur stated:

“Although the fossil record for eggs and nesting sites is extremely fragmentary, there is evidence to suggest that members of the Dinosauria exhibited altricial and precocial behaviours.  How one group of birds, the Neornithines were able to dominate the Aves remains uncertain, more research in this area is needed.  However, this data adds a fresh perspective and it is certainly intriguing.” 

Dr. Deeming advised that this new paper does not provide all the answers, but it hints at the tantalising possibility that eggshell morphology could have been an contributory factor in the extinction of the dinosaurs.  Dr. Deeming and this paper’s co-author Dr. Marcello Ruta (Lincoln University), are continuing their investigations.  The scientists intend to explore how highly variable amounts of yolk (food for the embryo) and albumen (egg white) could possibly effect egg shape.

Mary Anning at the Natural History Museum

Being Associated with the Wrong Marine Reptile

As team members from Everything Dinosaur travel around they sometimes get the chance to visit a natural history museum whilst out on their adventures.  There are many splendid museums in this country and elsewhere in the world and it is great fun looking at the various fossils held within the collections.  Occasionally, we come across an exhibit that has inaccurate or out of date information, mistakes do occur and we are always appreciative of the time and trouble curators take over their particular charges.

One such anomaly can be seen in the Fossil marine reptiles gallery in the Natural History Museum London.  There are some spectacular marine reptile fossils on display, Ichthyosaurs, Pliosaurs and their close cousins the Plesiosaurs.  The fossil specimens (most of them are casts) are truly astonishing and this museum (quite rightly in our opinion), does much to acknowledge the contribution of Mary Anning to the nascent science of palaeontology and her work excavating and describing fossils of ancient Jurassic marine vertebrates preserved in the cliffs on the Dorset coast around Lyme Regis.

Information about Mary Anning and her work can be found on various information boards on display.  However, one thing that has always puzzled us is that there is a prominent information board about Mary located on the Rhomaleosaurus cramptoni cast, Mary Anning had nothing to do with this specimen, its discovery or research into it.  In fact, she died about a year before this specimen was found.

Wonderful Marine Reptile Exhibits – but Nothing to Do with Mary Anning

Mary Anning died before this fossil was discovered.

The specimen in the photograph is not a fossil but a cast, a copy of the fossil which was made very probably in the late 19th Century by the American Henry Augustus Ward, who set up one of the world’s first fossil dealers and provider of museum replicas and casts.  The animal that the cast represents is called Rhomaleosaurus cramptoni.  It is pronounced Row-ma-lee-oh-sore-us.  It is mounted on the wall of the fossil marine reptiles gallery in the Natural History Museum, but we are aware of similar casts of the same fossil specimen in Monash University (Victoria, Australia), Cornell University, (New York USA), University of Illinois,  and the Bath Royal Literary and Scientific Institution (Bath, Somerset).

The actual fossil is part of the National Museum of Ireland (Natural History), Dublin, Ireland, we don’t think it is on current display.  The code for the specimen is NMING F8785 (all significant fossils are given a unique identifier, this helps when searching for information on a particular specimen).

Tracing the Origins of the Ichthyosaurs

Short Snouted Basal Ichthyosauriform from the Lower Triassic of China

It had long been predicted, but until now one of the enduring mysteries of the marine reptiles had remained unsolved.  One of the most successful clades of marine vertebrates ever to have existed were the Ichthyosaurs , reptiles that form the Order Ichthyosauria (fish lizards), also known as the Ichthyopterygia (fish flippers).  These animals thrived in the seas and oceans for much of the Mesozoic but unlike other types of back-boned animals that had adapted to a life in water, no fossils of transitional forms showing a link with terrestrial ancestors had been found.

However, this week a team of researchers led by scientists from the University of California have published a paper detailing the discovery of an amphibious Ichthyosaur, an animal that, although adapted to a life in the sea was still capable of clambering about on land.  This specimen is believed to represent a transitional form, between the Ichthyosauria and their terrestrial ancestors.  Writing in the science Journal “Nature”, the researchers document a nearly complete specimen (just end of the tail missing), of a forty centimetre long, amphibious reptile that is probably part of a group of animals that were the ancestors of the nektonic Ichthyosaurs, widely regarded by many palaeontologists as the most well-adapted to a marine existence of all the reptiles.

The Fossil Specimen that Indicates a Transitional Form

Cartorhynchus

Commenting on the research, lead author Professor Ryosuke Motani (University of California, Department of Earth and Planetary Sciences) stated:

 ”But now we have this fossil showing transition.  There’s nothing that prevents it from coming onto land.”

Professor Motani and his colleagues uncovered the fossil specimen in eastern China (Anhui Province) from Lower Triassic strata believed to date from around 248 million years ago (Olenikian faunal stage).  Unlike the long-snouted fully marine Ichthyosaurs this animal, which has been named Cartorhynchus lenticarpus, had a short snout, its bones were also heavier, traits associated with fully terrestrial ancestors.  Unlike later Ichthyosaurs, the flippers were large in proportion to the body size and the wrists flexible.  These features helped this creature crawl around on land, in a similar way to extant seals.  C. lenticarpus means “truncated snout with flexible wrists”, an apt name for this little reptile that spent part of its life on land.  During the early part of the Triassic, eastern China was covered by a shallow tropical sea, there were numerous small islands, the whole area resembled the Caribbean today.  The isolated islands with their limited resources probably acted as a spur for vertebrate evolution.  There was plenty of food in the sea but it was a question of being able to reach it, this probably led to the evolution of reptiles that were more at home in water than their ancient ancestors.

The researchers also had to consider the implications of the Permian mass extinction event on the evolutionary pressures that these animals were under.  Just four million years earlier, planet Earth had undergone the most devastating extinction event known in the history of our planet.  More than 95% of all life on Earth died out.

A spokesperson from Everything Dinosaur explained:

“Extinction events mean the inevitable demise of many genera and families.  However, for those organisms able to survive, such events open up a whole range of new opportunities and often there is a “burst” of evolution as animals and plants adapt to take advantage of vacated niches and new resources.”

Collaborating with the University of California were scientists from the Chinese Academy of Sciences, Peking University, Anhui Geological Museum, the University of Milan, and the Field Museum (Chicago).  As a basal Ichthyosauriform has been discovered in China, and the most primitive true Ichthyosaurs are also known from Triassic rocks from this region, then it is likely that the Ichthyosauria evolved in this part of the world.  This clade then radiated out and occupied a number of ecological niches including apex predatory positions before dying out in the Late Cretaceous.

Later Ichthyosaurs were agile, swimmers, although the end of the tail is missing, scientists speculate that Cartorhynchus lenticarpus was probably a relatively poor swimmer.  It probably hunted soft bodied animals and Arthropods in coastal waters.

Winner of Everything Dinosaur Competition Announced

Name an English Dinosaur “Anglosaurus lomaxi

In October, Everything Dinosaur ran a competition to win a signed copy of the terrific dinosaur book “Dinosaurs of the British Isles”.  This book, which was published in the summer, catalogues the dinosaur discoveries known from the British Isles and it was written by the highly talented Dean Lomax and Nobumichi Tamura.  Following a foreward by the eminent palaeontologist Dr. Paul Barrett, the authors summarise what is known about the history of every dinosaur species discovered within the British Isles.

Palaeontologist Dean Lomax kindly signed a copy and sent it over to Everything Dinosaur, we had a prize, now all we needed was a competition.  The contest we came up was to name an imaginary new species of English dinosaur.  We had so many imaginative entries, we can’t give everyone a mention but here’s a few…

  • “Herniornis Londonous” – Bubosaurus
  • “Ankyliceritops” – Heathyceritops
  • “Britanniasaurus” – Tom
  • “Blightyosaurus” – Aaron
  • “Elgaraptor” – Melanie

Congratulations to Diorama Winners

Dinosaur Toy Forum Winners Announced

Over the spring and summer, Everything Dinosaur sponsored a prehistoric animal modelling contest on the Dinosaur Toy Forum.  The standard of entries was extremely high and the subjects covered by the contestants varied and diverse.  There were scenes of many different types of dinosaur (the Papo Running T. rex being a particular favourite model used), Pterosaurs and some amazing marine reptiles, even some Temnospondyl amphibians entered the fray.  One of our personal favourites was “Life in the Precambrian” that used the innovative Toob of Precambrian critters made by Safari Ltd that came out last year.  It is always a pleasure to see how model makers use replicas imaginatively to recreate prehistoric scenes.

It was not just the excellent model making skills on display that impressed Everything Dinosaur team members.  Lots of creative use of photoshop was evident and we loved the titles that the artists had given to their exhibits.  For example, there were entries entitled “Breakfast at Tiffany” which featured the Collecta Stegosaurus corpse, “Desert Stand off”, “Heatstroke” and “Triassic Swim Lessons”.  Our congratulations to everyone who entered, it seems that model making is in fine fettle if the standard of entries in this competition are anything to go by.

As with all contests of this nature, there have to be winners and first prize goes to the forum member known as Federreptil for “Horrible Horn Horde”.

The detail is exquisite, we recognise a number of models and replicas in this Late Cretaceous scene, commenting on the winner a spokesperson from Everything Dinosaur stated:

“Clearly a great deal of work has gone into this diorama and the attention to detail is fantastic.  Although, the eye is drawn to the herd of Ceratopsians in the foreground, we loved spotting the other prehistoric replicas included in the scene, from the prehistoric plants and trees to the various Pterosaurs including Azhdarchidae”.

This is the second year in a row that Federreptil has won the contest, will anyone be able to challenge this talented model maker in 2015?

Second prize, as voted for by forum members goes to Seismosaurus of the United States for their entry called “On the Beach”.  This is a clever composition that depicts the tracks left by a Sauropod as it wanders along the sand.  The model used is the excellent Wild Safari Dinos Apatosaurus model (Safari Ltd).

Commenting on this composition, Sue Judd (Finance Director at Everything Dinosaur) explained:

“Although the model used is not that large, the artist has really created an impression of scale.  The angle of shot and the clever way in which the seascape background has been incorporated into the picture gives the impression of a huge Sauropod wandering along the shoreline of a Jurassic sea.”

Third place, in what was an incredibly tight contest, went to Irimali for the composition entitled “Separated from the Herd/Storm is Coming”.  A Camarasaurus is isolated and alone, or is it?  Lurking amongst the beautifully recreated Late Jurassic flora, a Theropod waits ready to pounce.

Commenting on the diorama, Mike Walley (Everything Dinosaur) said:

“The model maker has managed to create a very realistic Jurassic forest.  The models themselves are not the “stars” in this particular diorama, for us it is the way that the flora has been depicted.  The scene has been carefully constructed and the diorama has an eerie atmosphere enhanced by the clever use of the background which represents the misty depths of the forest.”

Everything Dinosaur will be in touch with the prize winners shortly so that their prizes (a selection of prehistoric animal models from Everything Dinosaur’s huge range), can be sent out to them.

Once again our congratulations to everyone who took part, we will try and feature the “honourable mentions” in a future blog post.

Geo Field Rulers Come in Handy

Showing the Size of a Dinosaur Model

We use lots of equipment on our various field excursions, everything from geological hammers, to plastic tubs, sieves, magnifying glasses and geo rulers.  Geo rulers are sturdy plastic rulers that are used to help measure and map fossil sites. They also come in handy when we want to show scale in any field photographs that we take.  Naturally, there is the old faithful geological hammer to use as well, but we sometimes prefer to show a more precise scale.  It is ironic then that we have found a new use for our geo rulers, they help us when we take pictures of various dinosaur models.
