Dinosaur Drawings and Letters from Year 2 (Great Wood Primary School)

Our thanks to the budding scientists at Great Wood Primary School in Morecambe (Lancashire), who sent into our offices some wonderful dinosaur illustrations and a set of beautifully written letters explaining how much they enjoyed their recent dinosaur workshop with one of our team members.  As part of our extension activity suggestions with the Year 2 classes we challenged them to design their very own prehistoric animal.  We received lots of amazing dinosaur designs.

Writing Thank You Letters

The teachers very kindly sent in thank you letters that the children had written.  Writing a thank you letter to Everything Dinosaur is a great way for the teaching team to check learning and understanding following a recounting activity.  This letter writing exercise helps young learners practice sentence sequencing, planning their composition, as well as spelling and the layout and format of a letter.  The children can also read their letters out aloud as part of a further teaching activity within the classroom.

A spokesperson from Everything Dinosaur commented:

“We try to provide additional teaching resources when we visit a school to deliver a dinosaur themed workshop.  In addition, during our workshop with the class the opportunity often arises to challenge the children to produce a piece of work, such as their very own dinosaur design or to write a thank you letter.  In this way, we are providing extension ideas to the teaching team and supporting the teacher’s scheme of work.”

Limited Edition Papo Spinosaurus – Further Update

At Everything Dinosaur, we try our best to keep model collectors and fans of dinosaur figures up to date with developments in the industry.  One of the most eagerly anticipated dinosaur models in years, the limited edition Papo Spinosaurus, has been subject to further delays and it is not likely to be in stock until October (October 2019).

In Stock October 2019

At a recent meeting with senior Papo team members, Everything Dinosaur pressed for an update on the new for 2019 prehistoric animal figures due to be added to the company’s “Les Dinosaures” range.  Prior to this most recent meeting, Everything Dinosaur had been informed that this figure was due to be launched in August/September.  We put out a release about this at the beginning of this month (June 2019), however, according to the latest information, the figure’s production and painting has been subject to further delays and this figure is not due to be released until October.

A spokesperson from Everything Dinosaur commented:

“We are working closely with Papo to ensure that production of these figures runs as smoothly as possible, Papo want to produce a truly spectacular dinosaur model and have been working hard to manage the production process.  As soon as we have further information about this eagerly anticipated prehistoric animal replica we will ensure that this information is posted up onto this blog and our various other social media platforms.”

Production Samples

During a very productive meeting with Papo, a number of important issues were discussed.  It is likely that the first production samples will be available late July, these will come straight from the factory and team members at Everything Dinosaur will be able to examine them and to post up further information and pictures.  At least that is the plan, but with a complicated large figure such as this Spinosaurus (it measures more than forty centimetres in length), some further delays could occur.

We are able to confirm that this figure will be provided in a special presentation box and the model will stand nearly seventeen centimetres tall (measuring the height of the sail).

Tale of the Tape – Papo Spinosaurus

The actual Papo Spinosaurus (S. aegyptiacus) measurements are:

length = 40.3 cm, width 10.5 cm and height (height of sail) 16.5 cm.

The new colour variant Papo Stegosaurus model is expected to arrive at the Everything Dinosaur warehouse very shortly, with the Pentaceratops and the Gorgosaurus models to follow later.

Dinosaur “Fossil Wall” Discovered in South-western China

By | June 17th, 2019|Adobe CS5, Dinosaur and Prehistoric Animal News Stories, Dinosaur Fans, Main Page, Photos/Pictures of Fossils|0 Comments

Treasure Trove of Dinosaur Fossils Discovered

Reports have been circulating from a number of Chinese media outlets concerning the discovery of an extensive fossil bed containing the remains of numerous dinosaurs in southwest China’s Chongqing Municipality.  The fossil site has been known about for several years but there have been a number of reports this week circulating, hinting at the extent of the fossil discovery and indeed, suggesting that it is very likely that as a result of excavation work, new species of dinosaur will be named and described.

The photograph (above), shows a Chinese field team member working on the “wall of dinosaur fossils”.  The site of the fossil find is described as a location close to Laojun village, Pu’an town, in Yunyang county.

New Dinosaur Species

The press reports state that scientists have identified different types of dinosaurs including theropods and basal ornithopods.  The disarticulated remains represent a bone accumulation and the strata is reported to be around 174 million years old (Aalenian faunal stage of the Middle Jurassic).  Commentators have described these fossil beds as very significant and likely to lead to the naming of new dinosaur species.

Four Thousand Individual Fossil Pieces

The mixed fossil assemblage has already provided researchers with around 4,000 pieces of dinosaur bone to study, since the site was first explored and mapped in 2017.

A spokesperson from Everything Dinosaur commented:

“The site has been described as exceeding 150 metres in length with at least 17 distinct assemblages of fossils within it.  Not much is known about the dinosaur biota from the earliest stages of the Middle Jurassic.  Once all the bones have been removed, prepared and studied it is very likely that several new species of dinosaur will be announced.  These dinosaurs will help palaeontologists to map the radiation and dispersal of several key groups of dinosaurs that were to dominate terrestrial ecosystems for the remainder of the Jurassic.”

The extensive fossil material could become China’s equivalent of America’s Dinosaur Monument in Utah.  The Dinosaur Monument represents a congregation of dinosaur fossils that accumulated in a river deposit.  Whilst similarities can be drawn between the two sites, the Chongqing Municipality deposits are approximately 25 million years older.

Perhaps, this could be China’s second “Great Wall”.

Don’t Get “Sniffy” About Dinosaur Sense of Smell

By | June 15th, 2019|Adobe CS5, Dinosaur and Prehistoric Animal News Stories, Dinosaur Fans, Main Page|0 Comments

Tyrannosaurs Had Their Noses in Front When it Came to Sense of Smell

A team of scientists from University College Dublin have built upon the idea put forward in earlier research indicating that many dinosaurs such as Tyrannosaurus rex had an impressive sense of smell.  In a recently published paper, the scientists examined the sense of smell of a wide range of living and extinct archosaurs and concluded that many different dinosaurs had an excellent olfactory sense but the Tyrannosaurs probably had one of the keenest senses of smell amongst the Dinosauria.

New Study Confirms T. rex Had a Powerful Sense of Smell

Olfactory Bulb Ratios

The brains of long extinct animals, like most soft tissues, are poor candidates for fossilisation, the size and the shape of an extinct animal’s brain can be inferred by looking at how the skull bones knit together to form the brain case.  It is from this data that the size and the proportion of the brain dedicated to processing sensory data such as the sense of smell can be deduced.  It has been stated in the past that approximately 50% of the brain volume of a T. rex was made up of the olfactory bulb, that part of the brain that processes smells.  Furthermore, in most modern animals, the size of the brain’s olfactory bulb also correlates with how well they can identify odours.  Looking at the ratio between that part of the brain dedicated to processing smells and the size of the entire brain (the olfactory bulb ratio), can also provide evidence as to the ecological niche an animal is likely to have occupied in an ecosystem.

The King of the Tyrant Lizards Top of the Table for Olfactory Abilities Too

Tyrannosaurs had a highly developed sense of smell.

For example, a bird that hunts in low light levels using scent to find food, is likely to have adapted to its environment very differently from that of a kestrel that hunts in daylight and uses its keen eyesight to spot its prey.

Writing in the journal “Proceedings of the Royal Society B”, Dr John Finarelli and his colleague Graham Hughes (University College Dublin), used the olfactory bulb ratio in living archosaurs (crocodiles and birds) to infer the strength of smell amongst dinosaurs.

Prior research has shown that the size of the olfactory bulb is related to the number of smell receptor genes in the DNA of a given animal and how much diversity they represent.  Taken together, it is called the olfactory repertoire. In this new study, the researchers used the olfactory repertoire of modern birds and an alligator to estimate the olfactory ability of several types of dinosaurs.  Based on this innovative research, the scientists concluded that T. rex probably had between 620 and 645 genes encoding its olfactory receptors, a gene count only slightly smaller than those in today’s chickens and domestic cats.  Closely related Tyrannosaurs such as Albertosaurus, also had substantial olfactory receptor gene counts.  Tyrannosaurs probably had the best sense of smell amongst the Dinosauria, this in turn can lead to inferences about how these theropods lived and behaved.

For example, Tyrannosaurs were probably able to “sniff out” prey from far away.  They were  able to track down the carcass of another dinosaur and scavenge the corpse.

A Good Sense of Smell Has Many Other Uses in the Animal Kingdom

The researchers hope that this new study will not get drawn into the “T. rex a hunter or a scavenger debate”, the authors stress that a good sense of smell has many other uses other than finding food.  Many animals use scent to mark and define territory, track down a mate, deter rivals and for intraspecific communication.  The University College Dublin scientists also highlighted a shift in scaling of olfactory bulb ratios to body size along the theropod lineage that led to the evolution of modern birds.  The researchers conclude that by combining morphological and genomic data, it can be demonstrated that, while genetic information for extinct taxa is forever lost, it is potentially feasible to investigate evolutionary trajectories in extinct animals.

Amongst Living Vertebrates, It is the Elephant that Tops the Table for the Most Olfactory Receptor Genes

Amongst all living vertebrates, the record for the most olfactory receptor genes lies with the modern elephant, a herbivore with about 2,500 such genes.  With such an exquisite sense of smell, elephants can “count” quantities of food by odour alone.  The researchers looked at a number of different types of dinosaur in their study, sure enough, some plant-eating dinosaurs showed evidence of a greater reliance on smell than some carnivorous dinosaurs.  For example, the Late Cretaceous herbivore Erlikosaurus (E. andrewsi), a theropod but a member of the Therizinosauridae had a greater number of projected olfactory receptor genes than Velociraptor and other predatory dromaeosaurids.

CollectA Caiuajara Pterosaur Model Gets Customised

Our thanks to dinosaur and prehistoric animal model collector Elizabeth who sent into Everything Dinosaur some photographs of her recent CollectA pterosaur purchase that she has had customised by a professional model maker and artist.  The pterosaur figure is the recently introduced (spring 2019), CollectA Supreme Deluxe Caiuajara model.  This figure has been highly praised by collectors and fans of prehistoric animals, but when placed in the hands of a professional model maker this figure can be customised and elevated to a higher level.

At Everything Dinosaur, we tend to get a lot of pictures of models that have been custom painted or altered by their owners in some way.  We marvel at how clever and creative these people are.    The CollectA Deluxe Caiuajara figure is very impressive, but the professional model maker (Martin Garratt),  has created a truly unique piece, one that would not be out of place in a museum collection.  Our congratulations to Martin for his excellent work and our thanks to Elizabeth for sharing images of the commission.

Colour Vision and Feathers

Recent research has suggested that members of the Pterosauria may have been feathered in a similar way as dinosaurs.  There is growing evidence to indicate that the common ancestor of the dinosaurs and pterosaurs may have evolved a coat of simple feathers to help this active animal keep warm.

A Pterosaur Starting Point

When it comes to customising a figure or model, it is very important to work with a highly accurate and well-made model in the first place.  If the figure has approximately the right proportions and has an intriguing pose that is anatomically accurate, then this permits the model maker the opportunity to really enhance the figure to create something truly unique.  Standing around twenty-four centimetres high, the CollectA Deluxe Caiuajara is quite sizeable and it has provided the model maker with lots of scope to really bring out the model’s features.  Martin’s choice of colour scheme is very effective and the use of starkly contrasting colours highlights that colour was most important to these flying reptiles and supports the idea that these active animals had colour vision.

The Model Maker has chosen a Vivid Colour Palette and Used a High Gloss Wash to Bring out Details

Feathers Came First Then Birds Evolved

By | June 8th, 2019|Adobe CS5, Dinosaur and Prehistoric Animal News Stories, Main Page, Palaeontological articles|0 Comments

Feathers Came First Then Birds Evolved

With the discovery of the amazing feathered dinosaur fossils from China, scientists have had to re-think their views about the appearance of dinosaurs, but the story of the evolution of the feather goes more than just skin deep.  In a follow up, to an earlier scientific paper published late last year that examined the evidence for four different types of feather in the Pterosauria, a team of researchers have concluded that the feather arose around 80 million years earlier than the first bird.  Furthermore, the study, led by scientists at the University of Bristol proposes that feathers played a significant role in helping to shape modern terrestrial ecosystems.

Not Just a Flight of Fancy – Feathers Change the Way We Look at Archosaurs

Numerous isolated feathers have been preserved indicating the presence of Avialae – primitive birds and theropod dinosaurs closely related to birds.  In addition, feather-like structures have been identified in pterosaurs.

Changing Our Understanding of Feathers, Their Function and Role in Evolution

Writing in the academic journal “Trends in Ecology and Evolution”, the researchers develop the work undertaken last year that looked at evidence for feathers in flying reptile fossils from China and utilises techniques deployed in molecular biology to plot the development of integumentary producing genes within the Archosauria.  If feathers did evolve in the Pterosauria as well as the Dinosauria, then this suggests that their common ancestor may have been feathered to.  Feather-like structures probably arose relatively early in the evolution of the Archosaurs.

Lead author of the paper, Professor Mike Benton (Bristol University), commented:

“The oldest bird is still Archaeopteryx first found in the Late Jurassic of southern Germany in 1861, although some species from China are a little older.  Those fossils all show a diversity of feathers – down feathers over the body and long, vaned feathers on the wings.  But, since 1994, palaeontologists have been contending with the perturbing discovery, based on hundreds of amazing specimens from China, that many dinosaurs also had feathers.”

Links Between Fish Teeth, Scales, Feathers and Mammalian Hair

Feathers are modified epidermal appendages that consist mainly of horn-like proteins (β-proteins).  Research has identified links at the genetic level between structures in vertebrates associated with shark teeth, dermal scales in teleost fishes, reptilian scales, feathers and mammalian body hair.  The discovery that genes specific to the production of feathers evolved at the base of the Archosauria clade rather than in association with stem members of the Avialae (birds), is supported by fossil evidence in the form of numerous examples of feathered dinosaurs including examples of feathers in Ornithischian dinosaurs as well as the Theropoda.  Many of the authors of this new paper also worked on the study into feathers in pterosaurs published in December last year.

If feathers evolved before the evolution of flight, they probably arose first as simple monofilament structures most likely to aid the retention of body heat in the archosaurian ancestors of birds and dinosaurs, perhaps first appearing sometime in the Early Triassic, a time after the Permian mass extinction which had led to a massive terrestrial faunal turnover and the evolution of more active animals with upright, erect gaits.

Co-author of the study, Baoyu Jiang from the University of Nanjing (China), added:

“At first, the dinosaurs with feathers were close to the origin of birds in the evolutionary tree.  This was not so hard to believe.  So, the origin of feathers was pushed back at least to the origin of those bird-like dinosaurs, maybe 200 million years ago.  In fact, we have shown that the same genome regulatory network drives the development of reptile scales, bird feathers, and mammal hairs.  Feathers could have evolved very early.”

Pterosaurs Had Feathers

The breakthrough for the research team occurred when two new types of pterosaur from China were studied.  Their pycnofibres showed branching, they did not have monofilaments but tufts and downy-like feathers, this led to the conclusion that members of the Pterosauria had feathers too.

Baoyu Jiang continued: “The breakthrough came when we were studying two new pterosaurs from China.

Professor Benton postulated that this area of research indicates the origins of feathers some 250 million years ago.

The professor explained:

“The point of origin of pterosaurs, dinosaurs and their relatives.  The Early Triassic world then was recovering from the most devastating mass extinction ever, and life on land had come back from near-total wipe-out.  Palaeontologists had already noted that the new reptiles walked upright instead of sprawling, that their bone structure suggested fast growth and maybe even warm-bloodedness, and the mammal ancestors probably had hair by then.  So, the dinosaurs, pterosaurs and their ancestors had feathers too.  Feathers then probably arose to aid this speeding up of physiology and ecology, purely for insulation.  The other functions of feathers, for display and of course for flight, came much later.”

The Importance of Kulindadromeus

Co-author Dr Maria McNamara (University College Cork, Ireland), explained that the discovery of a feathered dinosaur not thought to be closely related to birds has changed the way some palaeontologists view the evolution of feathers.  In 2014, a formal paper was published on a small, bird-hipped dinosaur that was named Kulindadromeus.  Fossils of this small, Siberian herbivore showed that it had skin covered with scales on the legs and tail, but strange, feathery filaments over much of the rest of its body.

Dr McNamara commented:

“What surprised people was that this was a dinosaur that was as far from birds in the evolutionary tree as could be imagined.  Perhaps feathers were present in the very first dinosaurs.”

Fellow co-author Danielle Dhouailly (University of Grenoble, France), studies the development of feathers in baby birds, especially their genomic control.  Her research has demonstrated that modern birds such as chickens often have scales on their legs or necks, these are in fact evidence of reversal, what had once been feathers had reverted to their more ancient form, that of reptilian scales.

This research supports the idea that gene regulatory networks show that the development of scales, feathers and hairs are co-ordinated by a similar set of genes.  Feathers and body hair probably evolved in the Early Triassic with the ancestors of mammals and birds, at a time when synapsids (the lineage of tetrapods that led to mammals) and archosaurs (dinosaurs and birds), show independent evidence of higher metabolic rates.  It was the mass extinction event at the end of the Permian that re-set the evolutionary clock and permitted the evolution of more active land animals, setting terrestrial lifeforms on a course that would ultimately lead to the rise of the dinosaur, volant flight in the Dinosauria and of course the evolution of modern mammals including ourselves.

Mojo Fun Prehistoric Mammals

Mojo Fun Prehistoric Mammals

The excellent “Prehistoric & Extinct” model range (Mojo Fun), contains a lot of dinosaur figures but today, we focus on a couple of prehistoric mammal models.  We have praised this model range before, congratulating the company for producing figures of recently extinct creatures such as the Quagga of southern Africa and the Tasmanian Tiger (Thylacine).  The range includes a number of other prehistoric mammals, replicas of some creatures that became extinct millions of years ago and not just within the last 150 years or so as in the case of the Thylacine and the Quagga.

Wide Temporal and Geographical Ranges

Mojo Fun have taken great care in the creation of their promotional image.  A spokesperson from Everything Dinosaur commented:

“It is always a pleasure to post up images depicting prehistoric animal models from the various ranges that we support.   We have some more images kindly supplied by Mojo Fun of some of their new for 2019 prehistoric animals, we are looking forward to posting up these images to, when the figures come into stock.”

Fossils of both Hyaenodon and Deinotherium genera have a wide geographical and temporal distribution.  H. gigas is known from the Lower Oligocene of south-eastern Mongolia, so it lived long before the first members of the Deinotheriidae evolved and certainly before the first members of this elephant family left Africa and became more widespread.  However, as the Deinotherium genus is believed to have existed from the Miocene to the Pliocene Epoch and as some hyaenodonts persisted until the Late Miocene, it is possible that species of Deinotherium would have been contemporaneous with some of the last members of the Hyaenodontidae.

An interaction between a member of the Deinotheriidae and a carnivorous hyaenodont could have taken place.

Examining a Jaw Fragment from a Dimetrodon

Examining a Jaw Fragment from a Dimetrodon

Team members at Everything Dinosaur had the opportunity to examine a jaw fragment from a Dimetrodon whilst on a visit to the National Museum (Cardiff).  This fossil, from a genus not associated with the British Isles, was part of an exhibit highlighting different types of reptile that existed prior to the evolution of the first dinosaurs.  Although, many museums around the world have extensive Dimetrodon fossil collections, it was pleasing to be able to have a really good look at the piece of jaw bone up close.

The teeth sockets can be identified and although the bone has some rather ominous looking cracks, two of the teeth have been preserved in situ.  We suspect that this is a piece from the dentary (lower jaw), Everything Dinosaur staff were unable to identify the Dimetrodon species from this fossil.  Unfortunately, the accompanying information panel did not provide details of where the fossil was found or which Dimetrodon species it had been assigned to.

Dimetrodon not a Dinosaur but Everything Dinosaur Likes to Feature this Pelycosaur

When posting up images of prehistoric animals like Dimetrodon on social media platforms such as Pinterest or Instagram, Everything Dinosaur is sometimes challenged and asked why a company so associated with the Dinosauria should post up images of a creature that was not closely related to dinosaurs?  However, as we provide such as wide variety of prehistoric animal models and figures, there is bound to be a bit of overspill out of the Dinosauria and into other tetrapods, indeed, we also supply models of plants, various extinct mammals and of course, plenty of Palaeozoic critters too!

Update on the Limited Edition Papo Spinosaurus

The limited edition Papo Spinosaurus model has been delayed and the original launch date for this eagerly awaited dinosaur figure has been put back with a release date now estimated at August/September.  Everything Dinosaur remains heavily committed to this figure and by delaying this figure by a few weeks, this does permit both Papo and ourselves to ensure a successful roll out of other new for 2019 Papo models such as the Gorgosaurus, the new colour variant Stegosaurus and the Pentaceratops model.

Latest news:  Now likely to be in stock in October.

Technical Issues

Technical issues have been cited as the reason for the delay.  With such an eagerly anticipated dinosaur figure, we are confident that design team at Papo and the production staff would be wanting to create the very best, most detailed model possible and therefore it may be sensible to take a little longer with the production process and the design of the special box that this figure will be presented in.

Everything Dinosaur team members have been involved in detailed discussions concerning the boxing of this figure.  As a business, we are trying to cut down on single use cardboard as part of our environmental policy, aiming to maintain our excellent record when it comes to recycling cardboard and paper.  However, a spokesperson from Papo’s senior management commented that the gift box “really highlights the premium value of this limited edition item” and added that “it’s also a good protection against shocks during the shipment.”

A spokesperson from Everything Dinosaur stated:

“All those people who are on Everything Dinosaur’s priority reserve list will still be offered a model, nothing has changed for them in terms of being guaranteed the chance to purchase this limited edition figure.”

The spokesperson went onto add:

“We have a meeting with Papo in a couple of weeks’ time, we hope to receive further information and if there is any additional news regarding this model or indeed any of the other new for 2019 figures such as the Papo Pentaceratops, the Gorgosaurus or the new colour variant Stegosaurus, we shall be sure to pass this information onto our customers”.
