Location : Europe

Metriacanthosaurus was a fairly large meat-eater that lived in Northern Europe near the end of the Jurassic Period. This carnivore was fairly typical of Jurassic theropods. It had long neural spines, but they were not significantly longer than those found on Allosaurus 

At one time Metriacanthosaurus was thought to be the same as Megalosaurus  but later studies showed that it was different enough to give it a new name. It actually took nearly forty years to distinguish Metriacanthosaurus from Megalosaurus
