Caulkicephalus was a flying reptile that soared over the Isle of Wight in England about 125 million years ago. It had a long, pointed beak and sharp teeth for catching fish. It was a pterosaur, not a dinosaur.4 1

趣味小知識：翼龍在恐龍頭上飛來飛去，但牠們是恐龍的親戚，不是恐龍喔。

酷東西

趣味知識

Its name means 'caulk head', because the first part of its skull was found in a rock that looked like caulk, a kind of sealant.1

Caulkicephalus had a special crest on its snout and another on top of its head, and these crests did not join together.1

It had different-sized teeth: the fifth, sixth and seventh teeth were smaller than the others.1

This pterosaur lived during the Early Cretaceous period, about 125 to 121 million years ago.4

Only a partial skull and some other bones have been found, so scientists are still learning about it.1

It was the second species of pterosaur ever discovered from the Wealden Group rocks of the Wessex Basin in England.1
