Magnon 5

From Tardis Wiki, the free Doctor Who reference

Magnon 5 was a planet populated by a tribe of warriors who had domesticated and trained dinosaurs. The Fourth Doctor landed on the planet to stretch his legs, but a malfunction in the TARDIS caused it to leave without him. The Doctor was hunted by the natives, who believed that he was a devil-man, but he escaped when the TARDIS again appeared. (PROSE: Entry 3512/A-7)
