Magnosaurus

Magnosaurus (meaning 'large lizard') was a genus of basal tetanuran theropod dinosaur from the Middle Jurassic of England. It is based on fragmentary remains and has often been confused with or included in Megalosaurus.

History and taxonomy
In 1923, Friedrich von Huene named Megalosaurus nethercombensis from a partial skeleton from the Aalenian-Bajocian-age Middle Jurassic Inferior Oolite, found in the nineteenth century by W. Parker near Nethercomb, north of Sherborne, in Dorset, England. The material included partial dentaries, dorsal and caudal vertebrae, a partial ilium, a partial right pubis, internal casts of the femora, and tibiae, from a possibly juvenile individual. Huene interpreted it as a more primitive species of Megalosaurus.
