pterosaur.jpg (41911 bytes)  

Pictured a pterosaur called Eudiomorphia. The animal had a wingspan of about 75cm.    The species is characterised by a short head and a bony tail, which makes up half the animals length.   The wings of the animal where formed by elongate skin membranes, which were joined to the elongate finger, and thigh of the animal.  This pterosaur is thought to have been an active flyer rather than a glider due to the muscle structure, and the tip of the tail was thought to be used as a rudder in flight. The skulls of the animal show a diapsid character.

This species was thought to be one of the first vertebrate to take to the skies.

The species shown is called Chasmatosaurus a species from the Early Triassic.  This species was 2m long.  The animal looks and probably acted rather like a modern crocodile.  This species was one of the firs well known archosaurs.  Each limb on the animal had 5 toes. The postulated mode of life for the animal was a fresh water habitat, suggested by the backward pointing teeth suggesting it was a fish eater.
