Woodlands of western Europe
Middle Jurassic (170 million years ago)

Not the most easily spelled (or pronounced) dinosaur, Dubreuillosaurus was only "diagnosed" in 2005 on the basis of a partial skeleton (it was originally thought to have been a species of the obscure predator Poekilopleuron). Now classified as a megalosaur, a type of large theropod closely related to Megalosaurus, Dubreuillosaurus was characterized by its unusually long skull, which was three times as long as it was thick.
