Pterodactyl
From Tardis Wiki, the free Doctor Who reference
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. ("DW: Invasion of the Dinosaurs).
