Protoceratops
From Tardis Wiki, the free Doctor Who reference
The Protoceratops were a type of dinosaur.
Whilst looking for Ace in Cretaceous Mongolia, the Seventh Doctor saw a protoceratops. (PROSE: Living in the Past)
Protoceratops were presumably one of the creatures that the Silurians bought back from extinction. They were allowed to roam free and possible used for food. (PROSE: Blood Heat)
