Concepts and Controversy

Endothermy / Exothermy Page 2

If Pterosaurs were exotherms it should be reasonable to expect to find an insulating mechanism. Evidence of what could be best described as fur had been describe as early as 1927, but the best evidence came during the 1970's. The Rhamphorhynchoid type Sordes (Mac/Win) described by Sharov, does have a very definite hair like covering on its body.

Most paleontologists would agree that Pterosaurs were warm blooded and this has obvious implications on the present debate over dinosaur blood temperature.
