Everything Dinosaur Stocks Rebor Yutyrannus Model

1:35 Scale Yutyrannus Model Added to Everything Dinosaur’s Range

For some time now, team members at Everything Dinosaur have been working with Rebor and the people behind this brand of new, highly collectible prehistoric animal replicas.  The first of the models in the Rebor series, the Yutryannus (Yutyrannus huali) is going to be in stock at Everything Dinosaur very shortly.  A few weeks ago, we made a quick video in our boardroom which introduces the Rebor range and looks at the Yutyrannus replica in detail.

 In this short video, five minutes and forty-seven seconds, we examine the packaging, discuss our involvement with Rebor and look at this beautiful tyrannosaurid model in more detail.  We comment on the integument that can be seen on the replica and explain a little about what is currently known about this particular feathered Chinese Tyrannnosaur.  Team members are finalising a fact sheet on this dinosaur, it is our intention to include this fact sheet with this new model, thus helping to provide collectors and dinosaur fans with a little additional information about this dinosaur, that was only formally named and described in 2012.

Everything Dinosaur Video Review – Collecta Bistahieversor

A Video Review of the Collecta Bistahieversor Dinosaur Model

Team members have been so busy preparing for new models as 2015 approaches that we have still got a couple of reviews of the 2014 releases to complete.  This is going to be rectified this month and the first of our last video reviews of new 2014 releases is a short video which features the rather wonderful Collecta Bistahieversor dinosaur model.

In the video (six minutes, forty-one seconds long), we discuss the significance of this New Mexico tyrannosaurid in terms of the provinciality of North American dinosaurs.  We look at the model and reflect on how this replica is based on the known fossil material.  We think this is our first feathered Tyrannosaur model video review, however, we suspect that it is not going to be our last.  Expect more feathered tyrannosaurids next year.

1:40 Scale Collecta Deluxe Therizinosaurus Video Review

A Video Review of the Collecta Deluxe 1:40 Therizinosaurus Dinosaur Model

Those clever manufacturers Collecta have made an excellent replica of the bizarre Theropod dinosaur known as Therizinosaurus.  We at Everything Dinosaur have made a short video review of this new for 2014 replica.  In this short video (six minutes and fifty seconds), we look at this model in more detail, discuss the fossil discoveries and compare this replica to the smaller, not to scale Therizinosaur model introduced by Collecta a couple of years ago now.

In this video we introduce Sir Arthur Gauge.  Sir Arthur is the name of the human replica that is included with many of the 1:40 Deluxe Collecta models.  He provides a scale for the replica in question.   In this particular case, estimating the scale of the Collecta Deluxe Therizinosaurus model is quite difficult, the fragmentary fossil material makes it tricky to provide a size guide for a fully grown animal. Some palaeontologists believe that Therizinosaurus cheloniformis weighed more than five tonnes and was over ten metres long.  Based on our estimates, we calculate that this figure is around 1:35 to 1:40 scale.

Collecta Mosasaurus Model Video Review

The Collecta Mosasaurus Model Video Review

The first account of a Mosasaur fossil was written in 1764, so 2014 marks the 250th anniversary of the publication of this information.  The fossil was found in Holland, near the town of Maastricht and here Everything Dinosaur team members contribute to the Mosasaur database by publishing our video review of the excellent Mosasaurus model made by Collecta.

Collecta made a not-to-scale replica of the Mosasaur known as Tylosaurus a few years ago now, this new, larger replica brings the Mosasauridae right up to date with pterygoid teeth depicted on the roof of the mouth and a spectacular tail fluke.  In this short video, (six minutes, forty-eight seconds), we point out these details and explain how this model reflects some of the latest scientific research on these amazing marine reptiles.

In the video, we also touch upon the chosen colour scheme of this model.  It does remind us of the markings on the extant Whale Shark (Rhincodon typus), the biggest fish alive today.  The largest members of the Mosasaurus genus would have grown to around the same length of a Whale Shark, perhaps fourteen metres or more, but the Whale Shark would have been many times heavier.  Whale Sharks may be gentle, slow-swimming plankton feeders but the Mosasaurs were fast-swimming, predators with the likes of Mosasaurus hoffmanni, whose fossils have been found in Holland, preying on other large marine vertebrates such as Plesiosaurs, large fish and turtles.

These reptiles were believed to have been predators of the surface waters.  Many palaeontologists think that these animals had relatively poor, stereoscopic vision so they would have most likely avoided the darker, deeper water, preferring to hunt in the relative shallows.  Whale Sharks tend to swim in the top 100 metres or so of the sea as they collect food with their huge, cavernous mouths, this might explain the colouration chosen for the Mosasaurus replica.

A Video Review of the Collecta Arsinoitherium Model

Collecta 1:20 Scale Deluxe Arsinoitherium Reviewed

Another day and another video review to post up onto the Everything Dinosaur blog, this time a video review of the Collecta Deluxe 1:20 scale model of Arsinoitherium.  One of the most bizarre-looking mammals that ever existed, if team members at Everything Dinosaur were asked to sum up this huge, plant-eater in one sentence, something like “here was a distant relative of elephants, that looked a bit like a rhinoceros and probably lived a bit like a hippopotamus”, would probably be appropriate.

The video runs for seven minutes and in the video we review this model, assign a species name to it and discuss what the fossil record tells us about these ancient creatures that roamed what was to become Egypt around thirty million years ago.  We even suggest some uses for those enormous horns that grew out of the skull.  The Arsinoitheres died out during the Mid Oligocene epoch and there is not a single species of animal alive today that is directly descended from this group, which is a shame.

Collecta Carcharodontosaurus – A Video Review

Collecta Deluxe Carcharodontosaurus Dinosaur Model Reviewed (Video)

With a new batch of Collecta Deluxe Carcharodontosaurus dinosaur models newly installed into our warehouse, it was time to make a brief video review of this dinosaur model.  Introduced  by Collecta in 2014, in the company’s Deluxe range of scale models of prehistoric animals, this replica of potentially one of the largest meat-eating dinosaurs that ever lived, has proved to be a big hit.  In this short video (seven minutes and twenty-two seconds), team members at Everything Dinosaur discuss the model in detail and provide information on the fossil discoveries made in Africa.

In this video we hint at the role that the sea may have played in the evolution of carcharodontosaurids and their eventual extinction.  A blog article has been prepared which provides further information on this theory.

This dinosaur genus provides and exemplar for the way in which study of the Dinosauria has progressed in the last decade or so.  The genus was erected in 1931 and it had one species assigned to it.  However, fossil discoveries in the late 1990′s led to the description of a second species (Carcharodontosaurus iguidensis).  This new species was announced just seven years ago.  It is likely that more species of carcharodontosaurid dinosaur (and abelisaurid, for that matter), will be discovered in Africa.

Look out for more news on the “shark toothed lizards”.

Evolution and Extinction of the African Carcharodontosauridae

“Shark Toothed Lizard” – The Rise and Fall of Carcharodontosaurus

The Carcharodontosaurus genus currently consists of two species, the first of which Carcharodontosaurus saharicus  (originally called Megalosaurus saharicus), is known from fossil material found in North Africa.  The second species, named and described in 2007, was erected following fossil finds, including skull material from the Echkar Formation of Niger, this species is known as C. iguidensis.  Although both species are known from fragmentary material and a few isolated teeth, differences in the shape of the upper jaw and the structure of the brain case enabled scientists to confidently establish Carcharodontosaurus iguidensis as a second, distinct species.

Carcharodontosaurus means “shark-toothed lizard”,  a reference to the fact that the teeth of this huge carnivore, reminded scientists of the teeth of sharks belonging to the Carcharodon genus of sharks, such as the teeth of the Great White Shark (C. carcharias).  It is ironic that this terrestrial predator should be named after a marine carnivore, as changing sea levels very probably influenced the evolution of these dinosaurs and may have ultimately led to their extinction, at least from Africa.

Pronounced - Car-car-oh-dont-toe-sore-us, the oldest dinosaur currently assigned to the Carcharodontosauridae family is Veterupristisaurus (Vet-ter-roo-pris-tee-sore-us).  This dinosaur was named and described in 2011, although the fossil material was discovered over seventy-five years ago.   The fossils come from the famous Tendaguru Formation of Tanzania, it lived during the Late Jurassic and the trivial name V. milneri honours the now retired Angela Milner who worked at the Natural History Museum (London).

Carcharodontosaurus lived during the Cretaceous (Late Albian to mid Cenomanian faunal stages).  During this time, the great, southern super-continent called Gondwanaland continued to break up and as sea levels rose, so populations of dinosaurs became separated by the inflow of sea water.

Rising Sea Levels Influence Dinosaur Evolution

Communities became isolated and this may have provided a boost to the evolution of new species.  The map shows the approximate location of fossil material associated with C. saharicus and C. iguidensis.  Populations of carcharodontosaurids may have become cut-off from each other and this gave rise to new species of Carcharodontosaurus.  This may help to explain the abundance of super-sized predators that lived in this part of the world during the Cretaceous.  Both species of Carcharodontosaurus shared a common ancestor, but their separation led to the evolution of two, distinct species.  This natural process is called allopatric speciation.

Sadly for the mega fauna that inhabited the coastal swamps and verdant flood plains of North Africa, rising sea levels in the later stages of the Cenomanian led to the destruction of much of this habitat.  The loss of habitat probably led to the demise of the ecosystem and the vulnerable apex predators such as the carcharodontosaurids and the spinosaurids became extinct.

A Video Review of the Collecta Saurophaganax Dinosaur Model

Collecta Saurophaganax – A Video Review

Everything Dinosaur team members have been busy writing scripts for video reviews on the latest batch of Collecta prehistoric animal models to be received into our warehouse.  The first of these model reviews features Saurophaganax, arguably one of the biggest meat-eating dinosaurs known to science.  In this short (six minutes, thirteen seconds) video, we look at the Collecta Saurophaganax in more detail, explain why there is still confusion over this genus and reflect on how a 145 million year old dinosaur is still capable of harming people today.

Ancient Creepy-Crawlies Resurrected

410 Million Year Old Arachnid Walks Again

A team of international researchers have used fossils of ancient Arthropods from the London Natural History Museum to recreate the movements of some of the world’s first terrestrial predators.  Researchers from the Museum für Naturkunde (Berlin) and Manchester University have used an open source computer programme called Blender to model the walking motion of a 41o million year old ancient Arachnid.  The video shows the most likely gait that this tiny prehistoric predator could achieve as it stalked across the Devonian landscape.  The paper, which details this research has been published in a special edition of the academic publication the “Journal of Palaeontology”.

The scientists took minute slices of the fossils of these early Arachnids and once the limb segments and their joints had been identified they worked out the range of limb motion possible.  From these measurements and using comparisons with extant Arachnids, the researchers modelled the walking action using the Blender software programme.  In this way, a creature dead for over 410 million years could once again walk.

Dr. Russell Garwood, (palaeontologist at Manchester University), stated:

“When it comes to early life on land, land before our ancestors came out of the sea, these early Arachnids were top dog of the food chain.  They are now extinct, but from about 300 to 400 million years ago, they seem to have been more widespread than spiders.  Now we can use the tools of computer graphics to better understand and recreate how they might have moved – all from thin slivers of rock, showing the joints in their legs.”

Supplemental Data Video 2 – Palaeocharinus Locomotion

The video shows the ancient Arthropod (Palaeocharinus genus) walking.  Although a formidable looking animal, this early creepy-crawly was less than half a centimetre in length.  The fossils used in this study came from the famous Lower Devonian strata at Rhynie (Aberdeenshire, Scotland).  The Rhynie chert deposit contains evidence of one of the earliest terrestrial ecosystems known to science.  More than twenty primitive plant species have been identified along with Arthropods such as mites and trigonotarbids such as Palaeocharinus that hunted amongst the miniature forest made up of Rhyniophytes (primitive plants).

Co-author of the scientific paper, Jason Dunlop (Museum für Naturkunde), added:

“These fossils,  from a rock called Rhynie chert, are unusually well-preserved.  During my PhD I could build up a pretty good idea of their appearance in life.  This new study has gone further and shows us how they probably walked.  For me, what’s really exciting is that scientists can make these animations now, without needing the technical wizardry and immense costs of a Jurassic Park-style film.”

Although not true spiders, trigonotarbids are related to modern spiders but they lack certain spider features such as silk producing spinnerets.  As a group, they first appear in the fossil record in the Late Silurian.  The oldest trigonotarbid specimen, that we at Everything Dinosaur know about, comes from the Upper Silurian deposits of Ludow , Shropshire (Ludlow epoch around 420 million years ago).  It was Jason Dunlop who was responsible for describing this discovery (1996).

The scale bar in the picture represents 2 mm.

Dr. Dunlop stated:

“When I started working on fossil Arachnids we were happy if we could manage a sketch of what they used to look like, now we can view them running across our computer screens.”

The development of sophisticated computer programmes is permitting scientists to re-create three-dimensional images of spectacular fossils.  In addition, new generation programming technology is now capable of bringing long extinct creatures back to life, at least in cyberspace.  The predatory Palaeocharinus might be quite frightening, but at half a centimetre long it would probably not even had got a second glance if you spotted on in the garden.  However, other specimens from Upper Devonian strata, as yet not fully described fossils, indicate that there were much larger creatures at home amongst the primitive plants such as the Rhyniophytes and Lycopsids (clubmosses), some fossils indicate Arthropods nearly an inch in length.  These creatures may not be trigonotarbids but perhaps represent an entirely new family of Arthropoda.

Dr. Garwood concluded:

“Using open source software means that this is something anyone could do at home, while allowing us to understand these early land animals better than ever before.”
