Proceratosaurus prohsuh-ratoh-SORRUHS

Proceratosaurus ( ) is a genus of theropod dinosaur that lived during the Middle Jurassic in what is now England. The holotype and only known specimen consists of a mostly complete skull with an accompanying lower jaw and a bone, found near Minchinhampton, a town in Gloucestershire. It was originally described in 1910 as a species of Megalosaurus, M. bradleyi, but was moved to its own genus, Proceratosaurus, in 1926. The genus was named for its supposed close relationship with Ceratosaurus, later shown to be erroneous, due to perceived resemblance of Proceratosaurus incomplete cranial crest to Ceratosaurus nasal horn.

A small to medium-sized dinosaur, the skull of Proceratosaurus is 26.9 cm long as preserved, and the dinosaur is estimated to have measured around 3 m in length.
