A migrating flock of pterosaurs appeared in the tv series along with ceratosaurus and euripterid. Several of them broke away from the rest of the flock and attacked the people on the beach. They took refuge in a large crevasse in the rocks but the pterosaurs followed. However, Macnif managed to scare them away by punching one in the eye, after wich they flew back to the flock.
They resemble large pteranodons, but have rhamphorynchus tails.
