Pterodactyl

Pterodactyl (meaning "winged finger") is a common term for some types of pterosaurs, generally the later, short-tailed varieties.

An unknown species of Pterodactyls appeared in London during the events of Invasion of the Dinosaurs. These Pterodactyls were brown aggressive, hawk-sized creatures who attacked the Doctor and Sarah Jane Smith in a pack. Another Pterodactyl was released near the Doctor when he was getting too close to Professor Whitaker's base.
