Caulkicephalus

Caulkicephalus is a genus of extinct pterosaur from the Isle of Wight off the coast of England. The new genus, whose name means "Caulk Head" (a nickname for Isle of Wight residents), was identified by a partial fossil skeleton and partial skull, including several teeth. The specific name for the pterosaur, trimicrodon, means "three small teeth".

From the evidence collected and comparison with other ornithocheirids, paleontologists have been able to determine that this pterosaur had a wingspan of around 5 meters (16 ft).
