A Review of the Guanlong Dinosaur Model (Wild Safari Dinos)

By | October 21st, 2011|Dinosaur Fans, Everything Dinosaur videos|0 Comments

Basal Tyrannosauroid Reviewed – Guanlong

One of the earliest members of that great Theropod dynasty – the Tyrannosaurs, Guanlong (Guanlong wucaii) has been a favourite for many years, well at least since 2006, the year this dinosaur was formally named and described.

This particular meat-eater, roamed the woodlands of what was to become north-western China in the Late Jurassic.  Measuring just three metres long and just 1.2 metres high at the hips, this fast running predator is believed to be a distant ancestor of the Late Cretaceous apex Tyrannosaur predators of the northern hemisphere.  It is hard to believe that this cursorial dinosaur with its long grasping hands and three, clawed fingers was an ancestor of Tyrannosaurus rex, Albertosaurus, Gorgosaurus and Appalachiosaurus.

We were delighted when Safari Ltd introduced a colourful model of this dinosaur, an addition to their Wild Safari Dinos model range.  A video review of this replica has been posted up on our Youtube channel and on Everything Dinosaur’s Facebook page.  We hope you like our video review of the Wild Safari Dinos Guanlong dinosaur model.

Comments and feedback would be welcome.  One thing worth noting, as fossils of Guanlong’s relative Dilong (Cretaceous dinosaur) have been interpreted as having proto-feathers, the model makers have followed the trend to show Guanlong covered in primitive feathers.  We like the way the coat of navy blue down contrasts with this dinosaur’s distinctive head crest, although are not sure how accurate the tail plume is.

The unusual crest that ran along the top of the snout was very thin and delicate, too delicate to be used in combat.  It was probably used for display either to attract a mate or to show maturity or perhaps to settle intraspecific squabbles.

Prehistoric Times (Issue 99)

Prehistoric Times Autumn 2011 – Reviewed

And so the penultimate edition of the dinosaur fan’s magazine before that all important centenary issue arrives and what a treat it proves to be.

In a novel twist, this issue of Prehistoric Times is available with two different front covers.  One copy has the armoured dinosaur Gastonia on the front cover, an illustration done especially for the magazine by William Stout.  The second version has a picture of a Styracosaurus model created by that highly talented sculptor and model maker Steve DeMarco.  We think (well actually we know because the editor told us), that there are plans to do something similar with the 100th edition.  For the record we were sent the Styracosaurus cover version and it was great to read the story of how Steve made this model in a feature entitled “One Horned Army”.

Amongst all the dinosaur and prehistoric fossil news, there is a super feature written by Tracy Lee Ford on how to draw Terror Birds, all part of his acclaimed “How to draw Dinosaurs” series, we won’t split hairs between avian and non-avian members of the Dinosauria but this article points out some potentially fundamental differences in bird versus dinosaur locomotion.  This suggests that birds may not be a good study model when considering how dinosaurs moved about.

James Field, that fantastic British prehistoric animal artist is interviewed and this edition features several of his beautiful illustrations.  Keeping up the British theme to this edition of Prehistoric Times there is a wonderful article by our dear chum Anthony Beeson on the development of the prehistoric animal model figures produced by the London Natural History Museum in conjunction with Invicta Plastics (Leicester).  The black Scelidosaurus (cost me 27 pence) is still amongst my favourite possessions and it was fascinating to read the first part of this article.  Part two will feature in the next edition.

As if all this and the “Mesozoic Mail” and letters page was not enough, there is even an article celebrating the 150th anniversary of Archaeopteryx and a pictorial tour of the new dinosaur halls at the Natural History Museum of Los Angeles.

With a feature on how to build your own model T. rex, an article on Gastonia, product reviews and the chance to enter the annual Prehistoric Times awards there really is some much in this edition, it is going to be hard for the team behind this magazine to top it for that special 100th issue.

Final Episode of “Planet Dinosaur” Reviewed

By | October 19th, 2011|Dinosaur and Prehistoric Animal News Stories, Dinosaur Fans, Everything Dinosaur News and Updates, TV Reviews|0 Comments

“The Great Survivors” – Nothronychus, Hatzegopteryx, Magyarosaurus et al

And so the BBC’s computer generated dinosaur series comes to an end with a programme that illustrated Dinosaurian diversity and this Order’s ability to adapt to different environments and exploit niches in the food chain.

It is always a pleasure to see an intepretation of a Therizinosaur and the Nothronychus footage helped demonstrate the diversity of the Theropoda.  Such bizarre creatures, and perhaps rivalling the likes of Gigantoraptor in this series for the title of “most bizarre dinosaur”.

Bizarre Theropod – Nothronychus

The concept of Theropods brooding their young was introduced with the Oviraptorids, using reference material from the American Museum of Natural History/Mongolian Academy of Sciences discoveries from the Ukhaa Tolgod region of south-western Mongolia.  Tyrannosaurids got a mention again, it was pleasing to see so many different members of this family depicted in the series, although one or two of the comments about them, one in particular about them being the dominant predator in their environments in the Late Cretaceous we could take issue with.  However, this is only a minor quibble.

The highlight in the last episode was the sequence with the Azhdarchid Pterosaur Hatzegopteryx.  We liked the clever use of camera angles to give the impression of the sizes of the Titanosaur, the Dromaeosaur and the Pterosaur.  It was interesting to note the depiction of this super-sized Pterosaur as a terrestrial carnivore, snatching up small dinosaurs in the same way that Maribou Storks do in Africa (except of course it is frogs and lizards etc).

Our Illustration of Hatzegopteryx

All in all, an enjoyable series and one we shall see again repeated many times, or perhaps we will treat ourselves to the DVD.

Guinness World Records Book – Reviewed

Team members at Everything Dinosaur have a new pastime, during their breaks they consult the Guinness World Records Book (2012 edition) and test each other on their knowledge on an amazing array of subjects from the moons of Jupiter to the shortest bird migration via trying to guess the country with the largest oil consumption.

The Guinness World Records book is absolutely stuffed full of astonishing facts, feats and statistics, if there is an area of human endeavour, an aspect of the natural world – animal, vegetable or mineral it seems that somebody, somewhere, holds a record and the Guinness team have set about compiling a immense compendium cataloguing it all.

A Sneak Preview New Prehistoric Animal Models for 2012 (Safari Ltd)

By | October 16th, 2011|Dinosaur and Prehistoric Animal News Stories, Dinosaur Fans, Press Releases|1 Comment

Peeping Behind the Curtain 2012 – New Dinosaur Models

Next year might be the year of the London Olympics, but for us one of the biggest events in 2012 is going to be the launch of new prehistoric animal models from Safari Ltd.

It is always exciting to see the introduction of new models into Safari Limited’s prehistoric animal ranges and the high quality of recent years is being kept up by the latest releases to be announced.

The big news is that the Carnegie Dinosaur Collectibles authentic scale model replicas is going to have a new Sauropod.  To accompany the recently introduced Diplodocus, next year a Brachiosaurus in 1:50 scale is coming out.  We said it was big news, the model measures a colossal fifty-five centimetres in length.  It is going to take up pride of place in many a model fan’s collection.  This new replica builds on recent research into the Macronaria and depicts Brachiosaurus as less massive, less “porky” as it were.

“Arm Lizard” – a new model

The neck is not fully upright, this is to our packing team’s relief as we anticipate a little bit of trouble getting this very large model to fit into padded envelopes for mailing out to customers.

In addition, Safari Ltd are adding four new replicas to their very well crafted Wild Safari Dinos range.  The new introductions are an eclectic bunch that is for sure, we have Dracorex, Ceratosaurus, Acrocanthosaurus and Vagaceratops.  The Dracorex is much more lithe than other models of this Pachycephalosaur and it is good to see the “Dragon King of Hogwarts” in this replica range.  For fans of meat-eating dinosaurs you have the Jurassic Ceratosaurus and the early Cretaceous Acrocanthosaurus to get your teeth into.  We made a friendly wager with another museum that we have not heard the last of Acrocanthosaurus and this American predator might well prove to be a contender for the biggest terrestrial carnivore of all time – we shall see.  Great to see another Ceratopsian represented, a really nice model of Vagaceratops, a Chasmosaurine whose remains are associated with Alberta and the Dinosaur Provincial Park.

New models from Safari Ltd

We are grateful to Safari Ltd for releasing the images to our Everything Dinosaur, team members.  We are all looking forward to 2012, looks like it is going to be an Olympic year for dinosaur replicas.

Create a Prehistoric Landscape

Inspired by all the good ideas and suggestions sent into Everything Dinosaur by all those enthusiastic dinosaur fans we wrote and article for an Ezine site on how to build your very own dinosaur play set.  This is a fun and easy thing to do.  Best of all it uses materials that would only have ended up going to recycling or being thrown out.

We have built a number of table top play sets, these allow children to learn about dinosaurs through creative play.  It also provides a handy storage area for the dinosaur toys “to live” without us grown ups tripping over them as they lie on the floor.

The Princeton Field Guide To Dinosaurs – An Excellent Reference Book

By | October 14th, 2011|Book Reviews|0 Comments

Book Review – The Princeton Field Guide to Dinosaurs – Gregory S. Paul

We had known about the launch of this book for sometime,after all, it came out last year and I recall reading the review out of Prehistoric Times magazine to colleagues at one of our  Friday afternoon meetings, but nobody took the hint and purchased it.  However, after having contacted the author on a technical issue concerning the anatomy of Spinosaurids I decided that enough was enough and I have bought it, using the excuse of an “early Christmas present to myself”.

For those not yet acquainted with the work and illustrations of Gregory S. Paul, let me quickly put you in the picture before providing a brief review of this offering.  Gregory S. Paul  is a world renowned illustrator of dinosaurs and prehistoric animals.  His enthusiasm for all things Dinosauria is quite remarkable and his research into this subject and deep understanding of these prehistoric animals makes him one of the most respected technical illustrators in the field of Earth Sciences.  He has produced a number of books related to palaeontology as well as being a frequent contributor to Nature and Scientific American as well as numerous other respected science-based journals.

The Princeton Field Guide to Dinosaurs – Reviewed

This publication is aimed at the casual reader as well as the serious academic, it combines beautiful anatomical illustrations and life-pose depictions with concise data on a vast range of the Dinosauria.  I note that the jacket states that more than 735 individual species are covered with over 600 colour and black/white illustrations, I won’t dispute these figures but suffice to say that this book is crammed full of dinosaurs, dinosaur illustrations and dinosaur facts and figures.

The book is laid out like a comprehensive field guide to the subject.  It reminds me of the sort of handy, practical guidebooks produced for enthusiastic ornithologists and bird spotters.  If one was able to travel back to the Mesozoic then this book would be just the thing to help the explorer distinguish between different Hadrosaurines should he or she encounter them.  A sort of “spotters” guide to dinosaurs with lavish accompanying notes.  If dinosaur fans have ever tried to unravel the differences between Euoplocephalus and Ankylosaurus then reading pages 233-235 would be a good place to start.

However, this book is not just a dinosaur directory, it starts with a comprehensive outline of dinosaur research, dinosaur discoveries and other information setting the scene for the descriptions that are to follow.  In fact, about one-fifth of the 320 pages or so are dedicated to providing detailed descriptions regarding dinosaur anatomy, physiology, behaviour and reproduction.  Each of these subject areas is broken down into manageable “chunks” before the major dinosaur groups are introduced.

The rest of this highly informative volume is dedicated to describing the various dinosaur families, genera and species.  Although it is not a comprehensive account, a number of “nomen dubium” the author has to be praised for featuring so many members of the Dinosauria.  We have already found it useful, helping to resolve the issue we encountered regarding the Spinosaurids.  “The Princeton Field Guide to Dinosaurs” has obviously been a labour of love and the author’s enthusiasm for these prehistoric animals really does come across.  Just a couple of quibbles, being based on this side of the Atlantic, (Britain) we note that this book is written in American English so expect to see words such as paleontology and behavior, rather than the English spellings.  Secondly, the back of the jacket shows a black and white illustration of a herd of mixed Sauropods.  The white area of the jacket is going to get quite grubby with all the handling, but these are really only minor points.

The overall layout is easy to follow, we loved the helpful guide to the group and species descriptions which included what we call a “taxonomic timeline” showing the different types of dinosaur families and when they lived.   Also, extremely useful is the well crafted index of taxa and the separate listing of geological formations referred to within the text.

We thoroughly recommend this book, do what I did and treat yourself to an “early Christmas present”.

Pushing the Boundaries of the Ornithocheiridae

By | October 13th, 2011|Dinosaur and Prehistoric Animal News Stories|1 Comment

Tiny Pterosaur Fossil Fragment Provides Insight into Biggest Toothed Flying Reptile

A tiny fragment of fossilised bone and a broken tooth stuck in a tooth socket have provided scientists with a tantalising glimpse into what may be one of the largest toothed, flying reptiles known to science.  The largest Pterosaurs known are the Late Cretaceous Azhdarchids, creatures such as Quetzalcoatlus and the recently discovered Hatzegopteryx (H. thambema).  These Pterosaurs (flying reptiles) had no teeth in their long jaws.  However, a team of British based researchers have found evidence of one type of toothed flying reptile that may have had a wingspan exceeding seven metres.  Such a creature could well be the largest known type of toothed Pterosaur to date.

There are several types of toothed Pterosaur known in the fossil record, but the research team focused on just one group, the Ornithocheirids.  Unlike other toothed groups, all of which were of relatively modest size (wingspans at most of 2 or 3 metres), they are known to have achieved very large and possibly even giant sizes with wingspans of 6 metres or more. Ornithocheirids were specialised fish-feeding Pterosaurs (their fossils are mostly associated with strata laid down in marine environments).  They used a fearsome set of teeth in the tips of the jaws, to grab their prey as they flew low and slow over the surface of the water.

New research from the Universities of Portsmouth and Leicester has identified a small fossil fragment at the Natural History Museum, London as being part of a giant Pterosaur  – setting a new upper limit for the size of winged and toothed animals. Dr David Martill from the University of Portsmouth and Dr David Unwin from the University of Leicester examined the fossil, which consisted of the tip of a Pterosaur snout that had been in the Museum collections since 1884.

Dr Unwin said:

“We found that, generally speaking, large Ornithocheirids reached wingspans of 5 or 6 metres which was consistent with previous ideas about this group.  However, we also came across one fossil, collected in the mid-19th century from a deposit in Cambridgeshire called the Cambridge Greensand that seemed to be unusually large.”

It may seem odd to find new evidence of giant Pterosaurs in a place such as the Natural History Museum, (London), you might expect all the fossils in such a collection to be very well known and previously studied.  This is not the case.  Firstly, the collections of these museums are vast and not all the material collected has been studied in great detail.  Secondly, many older specimens such as this particular fossil fragment which was donated to the museum in the 19th Century, may simply have been misidentified or incorrectly labelled.

Dr Unwin went onto add:

“This fossil, now in the collections of the Natural History Museum, London, consisted of the tip of a Pterosaur snout.  The shape of the snout and the broken-off tooth that it contained allowed us to identify the new find as belonging to Coloborhynchus capito, a very rare Ornithocheirid represented only by a few fossil fragments from the Cambridge Greensand.  Calculating the original size of the animal based on just a fragment is difficult, but we were able to take advantage of some recent finds in Brazil of almost complete skeletons of Ornithocheirids that are closely related to the Cambridge Greensand jaw fragment.  Our study showed that the fossil did indeed represent a very large individual with a wingspan that might have reached 7 metres.”

Significantly, though, this is still far short of the giant size achieved by some toothless pterosaurs. Several species of a group called Azhdarchids, such as Quetzalcoatlus achieved wingspans of around ten metres.  We can expect the Azhdarchidae to make the headlines again when a recently discovered giant European Azhdarchid Pterosaur is featured in the next and final episode of the BBC television programme “Planet Dinosaur”.  The Pterosaur concerned is Hatzegopteryx thambem, fossils of which have been found in the Hateg Basin of Translyvania.  Everything Dinosaur was given the task of reviewing the book that accompanies the television series, and a very good book it is to.  However, in our notes we did record the bizarre statistics given in this book for this Pterosaur.  The wingspan was stated as being 10-12 metres, we can live with this estimate but the weight – that is a different matter.  Buy the book turn to page 204 and see for yourself.

The challenge for the researchers now is to try to understand why some groups, such as Azhdarchids, reached these giant sizes, while toothed forms, such as the Ornithocheirids, did not.  Teeth are heavy, so part of the explanation may lie in weight reduction by losing these.

Dr Unwin concluded:

“This research is important because it helps us to better understand patterns of evolution over millions of years, and in groups that are now extinct.  At a more general level, it feeds into TV documentaries such as the current series ‘Dinosaur Planet’ on BBC1, ensuring that they have the ‘ring of authenticity’ that ensures successful reception, by experts and the lay public alike.  Indeed, these programs are enormously popular, as viewing figures show, allowing us to comfort ourselves with the thought that the research we carry out is helping to satisfy the interests of a not insignificant portion of the viewing public.  For Dave Martill and I, this was to some extent the ‘bread and butter’ stuff that we do everyday.  But it’s this slow piling up of data and, critically, its connection into our general understanding, that leads to the really big discoveries. Dave likes to refer to the fossil as the ugliest fossil he ever studied, and I can see his point, but as I did my PhD on Cambridge Greensand Pterosaurs they have a special place in my affections and, no matter how ugly, I still love them.”

Like Dr Unwin we too have a lot of affection for the Ornithocheirids, they are an exceptionally difficult group to study, as most of the fossil material associated with them is extremely fragmentary.

We are grateful to the University of Leicester for their help in compiling this article.

Planet Dinosaur Episode Five Reviewed – “Giant Killers”

By | October 12th, 2011|Dinosaur Fans, TV Reviews|0 Comments

Argentinosaurus, Mapusaurus, Sarcosuchus et al

And so the fifth instalment of the BBC television series “Planet Dinosaur” is reached.  This episode entitled “Giant Killers” introduced a number of new prehistoric animals such as the nest raider Skopiovenator, an Abelisaurid formally named and described just two years ago as well as some dinosaurs that are already very familiar to dinosaur fans.  One of those dinosaurs regarded as “familiar” would be Argentinosaurus (A. huinculensis), recognised as the largest dinosaur known to science, indeed the largest terrestrial animal of all time.  With an estimated length of thirty-five metres and a mass of seventy-five tonnes, the programme makers did their best to convey the sheer size of this Titanosaur, we liked the clever use of the small Ornithopods running alongside.  Interestingly, the footprint death traps that  proved so fatal to these are not from South America, but China.  The programme rather glossed over this point.  The treacherous trackways have been associated with the Sauropod Mamenchisaurus, although ichnologists would argue that it is difficult to assign a genus to a set of tracks unless a specimen representing the animal that made them is found fossilised at the trackway’s end.

The main thrust of the programme seemed to focus on the fossil evidence to suggest that large carnivores (Theropoda and a prehistoric crocodile) lived alongside large herbivores (Sauropoda).  The programme suggested that when the large herbivores became extinct, the large meat-eaters that depended on them soon died out as well.  This is an extension of the predator/prey relationship that was discussed in earlier programmes.

The time lapse imagery showing the scavenging of a Titanosaur carcase was for us, the highlight of this particular episode, although it was a pleasure to see Sarcosuchus (prehistoric crocodile) once again.  This eight tonne super-croc was first seen in episode one “”Lost World”.   The narration claimed that Sarcosuchus was the biggest crocodile.  From what the fossil record shows, it was certainly was the biggest in that part of the world during the Cretaceous, but other crocodiles such as Deinosuchus and the much later Purussaurus could lay claim to being the biggest crocodile of all time.

The South American Theropod Mapusaurus (Mapusaurus roseae) was also introduced.  We suspect that for many young dinosaur fans, this is a new meat-eater for them.  The fossils of this dinosaur come from the Huincul Formation in the Rio Negro and Neuquen provinces of Argentina.  This carnivore was a contemporary of Giganotosaurus and may have been a pack hunter, an animal that weighed perhaps as much as six tonnes.

Still our favourite has to be Sarcosuchus, I guess we just have a soft spot for those big crocs.
