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. 

Name Meaning

Metriacanthosaurus means "medium spine lizard".


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.

Appearance and Size


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.


Unlike the actual species, these clones are a meter smaller.


Jurassic Park  (Intimated in 1993)

Metriacanthosaurus was recreated by InGen in the InGen Compound on Isla Sorna. Metriacanthosaurus was planned to live in its own paddock on Jurassic Park probably during Phase 1 or Phase 2.

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.

Jurassic World

InGen recreated Metriacanthosaurus again for Masrani Global Corporation's Jurassic World. The new clones lived in the Cretaceous Cruise. Unlike the actual species, these clones are a meter smaller. After Jurassic World, the Dinosaur Protection Group confirmed its extinct on Isla Nublar.
