Rare Prehistoric Mammals and the Ascent of Man Series Soon to be Available

Team members at Everything Dinosaur are pleased to announce that negotiations with Bullyland, the Germany-based figure and model manufacturer have been concluded successfully and the UK-based dinosaur company will soon be getting a range of rare Bullyland prehistoric animal models and early human figures into stock.

Bullyland Prehistoric Animal Models

Over many years, Bullyland have built up a substantial back catalogue of prehistoric animal models, including Mastodons, Chalicotheres, Deinotherium, Woolly Rhinos, Ancient Horses, Irish Elk and Terror Birds.  Customers of Everything Dinosaur will soon be able to get their hands on these rare, hand-painted models.  However, these models will only be available for a limited period.

Everything Dinosaur’s museum contacts informed them that Bullyland was going to produce a small run of its retired prehistoric animal and human figures for sale within the German museum market.  However, thanks to the company’s close relationship with Bullyland and its expertise in the field of prehistoric animal figures, Everything Dinosaur is to be supplied with a limited stock of the models.

A spokeswoman for Everything Dinosaur stated:

“We are delighted to see a number of the previously retired Bullyland models come back.  These once extinct replicas so sought after by collectors are now available once again.”

However, it was pointed out that a number of enthusiasts and collectors had already placed orders with Everything Dinosaur, so the spokesperson added:

“This is really an exciting opportunity for collectors to get hold of some extremely rare models, we suspect that demand is going to outstrip supply for a number of replicas, so it is going to be a case of first come, first served.”

Model collectors can contact Everything Dinosaur, and express their interest in prehistoric animal replicas including the Bullyland prehistoric animal models by emailing the company: Email Everything Dinosaur.

Models can then be reserved and the customer contacted when the shipment arrives (scheduled to be available by mid June).

It is not just prehistoric animals that are being re-introduced, the famous and almost mythical “evolution of mankind” series of models is also going to be available.  This series featured six hominin models that portrayed the evolution of our own species.  The first model is a replica of the ape Dryopithecus, this is followed by an Australopithecine, Homo habilis, Homo erectus, a Neanderthal and concluding the set a replica of a modern man, referred to by Everything Dinosaur staff as the “Clovis Man Replica”.

As if all these models was not excitement enough, Everything Dinosaur have one more surprise hidden away in the geology ruck sack.  The company has been able to secure a limited stock of the exceptionally rare Bullyland Mastodonsaurus model.

Mastodonsaurus was a large-headed, giant amphibian belonging to the temnospondyl clade.  It lived in the Triassic and some species grew to the lengths of modern-day caiman.  A fierce predator, it is great to see a model of this prehistoric animal available once again.  An example of an creature thought to be extinct, coming back from the dead perhaps?

Dinosaurs Lighter Than Previously Thought According to New Research

University of Manchester Scientists “Slim down the Dinosaurs”

How big were the dinosaurs?  This is a question that has vexed palaeontologists ever since the first fossil bones of these prehistoric animals were studied in detail.  The size of extinct animals can be calculated by measuring the length of individual bones but the calculation of mass is much more difficult.  Scientists at the University of Manchester have developed a new technique that “slims down” the Dinosauria.  Some of the largest leviathans may not have weighed upwards of eighty metric tonnes as previously thought, around twenty-three tonnes may actually be nearer the mark.

How Big were the Dinosaurs?

Just how big were the dinosaurs has sparked lively debate for many years, to read an article on the possible size and weight of Brachiosaurus (published in 2009): Just how big was Brachiosaurus?

Palaeobiologists at the University have developed a new technique to accurately measure the weight and size of dinosaurs and discovered they are not as heavy as previously thought.  University of Manchester biologists used lasers to measure the minimum amount of skin required to wrap around the skeletons of modern-day mammals, including reindeer, polar bears, giraffes and elephants.  Using animals alive today, that can be weighed allows the researchers to test their calculations against the actual  recorded weight of the animal.

What the laser mapping technique shows, is that the dinosaurs may not have been as heavy as earlier estimates.  This has implications for the study of their behaviour and locomotion, even whether some of the biggest dinosaurs of all – the long-necked sauropods may have been capable of rearing up onto their hind legs.

Research from Manchester University

The Manchester based team discovered that the animals they measured had almost exactly 21% more body mass than the minimum skeletal “skin and bone” wrap volume.  They then applied this to a giant brachiosaur skeleton in Berlin’s Museum für Naturkunde, (Humboldt Museum).  This skeleton stands over forty feet tall, and is made up of the fossilised bones of several individuals.  It represents a brachiosaur from Africa and it is the largest mounted dinosaur skeleton on display in Europe.

Estimating the Weight of Brachiosaurus

Previous estimates of this brachiosaur’s weight have varied, with estimates as high as 80 tonnes.  The Manchester team’s calculations – published in the journal Biology Letters – reduced that figure to just 23 tonnes.   Still a substantial weight, but intriguingly establishing the giant mammals known as the Indricotheres as potentially the heaviest land living animals known to science.  The team says the new technique will apply to all dinosaur weight measurements and thus the mass of all the known dinosaurs can be calculated.

Commenting on the research, lead author Dr Bill Sellers said:

“One of the most important things palaeobiologists need to know about fossilised animals is how much they weighed.  This is surprisingly difficult, so we have been testing a new approach.  We laser scanned various large mammal skeletons, including polar bear, giraffe and elephant, and calculated the minimum wrapping volume of the main skeletal sections”.

Arguments Put Forward

One of the arguments put forward against depicting the dinosaurs as more agile, active creatures was their great size and weight.  Despite a number of evolutionary adaptations to lighten their skeletons such as the evolution of pneumatised bones.  Many scientists had argued that predators such as Tyrannosaurus rex would have been just too heavy and slow to be effective hunters.  It has been proposed that these heavy carnivores probably scavenged carcases.

Dr Sellers went onto state:

“We showed that the actual volume is reliably 21% more than this value, so we then laser scanned the Berlin brachiosaur, Giraffatitan brancai, calculating the skin and bone wrapping volume and added 21%.  We found that the giant herbivore weighed 23 tonnes, supporting the view that these animals were much lighter than traditionally thought.”

Dr Sellers, based in Manchester’s Faculty of Life Sciences, explained that body mass was a critical parameter used to constrain biomechanical and physiological traits of organisms.

He added:

“Volumetric methods are becoming more common as techniques for estimating the body masses of fossil vertebrates but they are often accused of excessive subjective input when estimating the thickness of missing soft tissue. Here, we demonstrate an alternative approach where a minimum convex hull is derived mathematically from the point cloud generated by laser-scanning mounted skeletons.  This has the advantage of requiring minimal user intervention and is therefore more objective and far quicker.”

Brachiosaurus or Giraffatitan

Interestingly, as scientists debate the body weights of brachiosaurs, it is worth noting that until recently the brachiosaur in the Berlin museum was described as belonging to the genus Brachiosaurus.  However, studies of the fossil material ascribed to this genus that had been found in East Africa and the Western United States indicate that the African material is sufficient different to be put into its own, separate genus – Giraffatitan.

To read an article on the scientific debate between Brachiosaurus and Giraffatitan genera: Brachiosaurus versus Giraffatitan.

Explaining how the research team estimated the weight of the Berlin specimen, Dr Sellers stated:

“We tested this method on 14 large-bodied mammalian skeletons and demonstrated that it consistently underestimated body mass by 21%.  We suggest that this is a robust method of estimating body mass where a mounted skeletal reconstruction is available and demonstrate its usage to predict the body mass of one of the largest, relatively complete sauropod dinosaurs, Giraffatitan brancai, as 23,200 kilogrammes.”


When asked to put this new research into the context of earlier studies that had produced much higher weights for dinosaurs, Dr Sellers commented:

“The value we got for Giraffatitan is at the low range of previous estimates; although it is still huge, some of the enormous estimates of the past – 80 tonnes in 1962 – are exaggerated.  Our method provides a much more accurate measure and shows dinosaurs, while still huge, are not as big as previously thought.”

The Weight of the Dinosauria

The debate over the weight of the Dinosauria, especially the really big sauropods is likely to rumble on.  Still at twenty-three metric tonnes, this makes one particular Late Jurassic sauropod much heavier than any land living animal alive today.  This dinosaur would be many times the weight of the biggest elephants.
