Metriacanthosaurus was a fairly large theropod dinosaur that lived in Northern Europe near the end of the Jurassic Period. This carnivore was fairly typical of Jurassic theropods. Metriacanthosaurus gets its name for its backbones, which have spines on top that are taller than in many meat-eaters (such as Allosaurus or Tyrannosaurus) but much smaller than those of Spinosaurus.
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!
Because so little is known about this dinosaur, any pictures of it or speculation on its habits are based on comparisons with meat-eating dinosaurs of which we have more complete skeletons.
It is unknown if any Metriacanthosaurs were on Isla Nublar, though an x-ray of its skull inside the Isla Nublar Field Lab could imply that there could have been at least one on the island. It is also unknown if Metriacanthosaurus was one of the dinosaurs that survived being wild on Isla Sorna after Hurricane Clarissa.
InGen recreated Metriacanthosaurus again for Masrani Global Corporation's Jurassic World. These Metriacanthosaurus had some form of proto-feathers on their arms and up and down their spine. The color of these clones was brown with orange stripes on its body and tail and black stripes on its face and lime green on its crests. The new clones lived in the Cretaceous Cruise. Unlike the actual species, these clones are a meter smaller.
