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).

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.”

Collecta Quetzalcoatlus with Prey Video Review

A Video Review of the Quetzalcoatlus with Prey Model (Collecta)

In 2014, those clever people at Collecta introduced another Pterosaur model into their not-to-scale range of prehistoric animals.  Not only did this new figure depict a flying reptile on the ground and not in a flying pose with wings outstretched, it also portrayed Quetzalcoatlus as a hunter of dinosaurs.  The Quetzalcoatlus with prey model shows this large Pterosaur with a baby Alamosaurus in its huge beak.

In this five minute video (four minutes fifty-seven seconds), Everything Dinosaur looks at this model in a little more detail.  Why the unfortunate Alamosaurus model was chosen as the prey is explained and team members comment on the colouration, size and scale of this replica.

As for pronunciation, the only species in the Quetzalcoatlus genus named to date is Q. northropi named in 1975.  The genus name comes from the feathered serpent God of  the Aztec people called Quetzalcoatl.  The genus name is pronounced kwet-zal-co-at-lus or kwet-zal-coat-lus, but one thing is for sure, the genus name of this  huge, Late Cretaceous, azhdarchid Pterosaur needs a bit of a run up when it comes to saying it.

Wild Safari Dinosaurs Ammonite Model – A Video Review

Video Review of Ammonite Model

Safari Ltd have introduced a replica of an Ammonite into their Wild Safari Dinosaurs model range.  This model series certainly has a lot more than just dinosaur models to offer collectors and this new Ammonite replica is a welcome addition.

In this short video review (six minutes and twelve seconds long), Everything Dinosaur discusses the merits of this model and explains why its introduction will prove very helpful to teachers and fossil collectors.

Although the soft parts of members of the Ammonoidea are virtually unknown in the fossil record, this replica reflects what palaeontologists actually think that the soft tissues of Ammonites looked like. From the front the animal looks quite foreboding with its two long tentacles and eight muscular arms.  Imagine how you would feel if a three metre long specimen came hurtling towards you out of the dark waters – very scary!

The Wild Safari Dinosaurs Ammonite model and the rest of the Safari Ltd prehistoric animal model range can be seen here: Safari Ltd Prehistoric Animal Models

This Ammonite model is great for use in schools as a teaching resource and it will also find a role in helping to explain Ammonite fossils in museum display cases.
