Caulkicephalus Trimicrodon

Great things are happening on the Isle of Wight a new species

of pterosaur is about to be announced.

After a dedication of some twenty years Mr J Winch from the island has hit gold!! We all dream that one day all the years of fossil hunting will be rewarded with a one of a kind discovery and the opportunity to name your find, however on this occasion Dave Martell named the new pterosaur. The fossils have been inspected by Dr D Martell and it could well be new to the UK. A paper on these findings will shortly be published!! (Cretaceous Research) The Big Dig has covered part of the history behind the find.


The Cretaceous scene

The Pterosaur was probably washed into a pocket where debris, such as plant material ,had collected from a river. Due to the size of the bones found and their delicate composition the river was either tidal or slow flowing. The bones have not been distressed or rolled from constant movement and do not reveal rounded edges. Teeth were not found in their sockets or around the specimen in situation,the socket sizes indicate that the teeth would have been 2-3 inches high including the root base had they been present however they were probably washed out and away from the specimen during its' relocation.

We can reveal that a shark was found next to the specimen, it is known to have been a fresh water shark. Further investigations also revealed lots of unios, which are fresh water muscles. Given these additional findings we can safely assume this was the site of a river or marsh land. The pterosaur may have been skimming the water for fish or wading.There is evidence along the beach of footprints we can assume the ground was wet at the time of the prints being left, perhaps the banks of a river or boggy marshland. Therefore it could be suggested that this was a feeding area or even a crossing place for the surrounding inhabitants aswell.

With so much traffic around we could even suggest that this was a popular site for pterosaurs and in a bid for the territory our pterosaur may have been killed, perhaps during an aerobatic fight only to fall to an inevitable death and sink into the marsh land. Only later to be deposited by a freak flood in a pocket of water and mud as the water dropped and sediment covered it. This would explain why there are missing elements to the full skeleton.
