Tiny fossil fragment reveals giant-but-ugly-truth
Date:10/13/2011

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.

Their identification of the fossil as being part of the world's largest toothed pterosaur has been published in Cretaceous Research.

Dr Unwin, from the School of Museum Studies at the University of Leicester, said: "Our study showed that the fossil represented a huge individual with a wingspan that might have reached 7 metres. This is far larger than, for example, any modern bird, although some extinct birds may have reached 6 metres in wingspan.

"What this research shows is that some toothed pterosaurs reached truly spectacular sizes and, for now, it allows us to put a likely upper limit on that size around 7 metres in wingspan."

Dr Martill, from the University of Portsmouth, added: "It's an ugly looking specimen, but with a bit of skill you can work out just exactly what it was. All we have is the tip of the upper jaws - bones called the premaxillae, and a broken tooth preserved in one socket.

"Although the crown of the tooth has broken off, its diameter is 13mm. This is huge for a pterosaur. Once you do the calculations you realise that the scrap in your hand is a very exciting discovery.

"The specimen was placed in the collections of London's Natural History Museum by Sir Richard Owen, perhaps the world's greatest vertebrate palaeontologist. In his day, Owen reconstructed a giant New Zealand Moa from a single bone. We might never achieve Owen's calibre, but it is nice to think that we are following in his footsteps."'/>"/>
