Megalosaurus

The Megalosaurus (Megalosaurus bucklandi) was a type of theropod dinosaur. It was around 9 feet long and 3 metres in height. It was found in Eurasia, specifically the parts that would later be known as England and France. It died out in the Jurassic period from environmental changes.

The last Megalosaurus was saved and kept in the Museum of the Last Ones. After the Tenth Doctor's meddling, it was accidentally released into its habitat. Unfortunately, it lived in what was later a town in England. After running amok and fighting with one of the cloned sabre-toothed tigers, the Doctor was able to freeze it in time and return it to the past. The Megalosaurus was worth 400 points in the I-Spyder Book of Earth Creatures. (NSA: The Last Dodo)
