While reading that the cranial crest of the pterosaur Thalassodromeus helped regulate body temperature, I pondered another potential use. While gliding near the water, its crested head might act as a rudder for the large-wingspan animal. Perhaps the crest also included nerves that allowed Thalassodromeus to sense fleeing fish.
