'Metriacanthosaurus is a genus of carnivorous dinosaurs. It belongs to the recently classified Sinraptoridae, which is its own distinct family, in its own right - like so many other Victorian Era discovered theropod Dinosaurs, the fossils of what were to be named Metriacanthosaurus, were dumped in the 'wastebasket taxon' of Megalosaurus, which was thought to have been a genus of dozens of species. In time, Paleontologists shunned the old ways which were lazy and inaccurate, leading to many so called Megalosaurs being reclassified as something else. In some cases, the 'Megalosaur' remains did not even belong to any kind of Dinosaur. Sinraptor, from China, is one of its closest relatives. The only species that is known of this genus is Metriacanthosaurus parkeria. This Theropod lived during the late Jurassic Period of Europe, hunting contemporary herbivores, such as Callovosaurus.

In 1923, the paleontologist Friedrich von Hume described a few fossils and concluded that they belonged to a new species of the Megalosaurus genus. In the 1960s Alick Walker concluded that the fossils where to different from Megalosaurus and concluded that this species belonged to a unique genus, he called Metriacanthosaurus. The species was named P'arkeria.

In 1977, an almost complete skeleton of large Theropod was discovered in China. It was classified as a new species (shangyouensis) and a member of a new genus (Yangchuanosaurus). According to Gregory S. Paul, the genus Yangchuanosaurus was identical to the genus Metriacanthosaurus and therefore classified the animal in 1988 as Metriacanthosaurus shangyouensis. But this reclassification was later canceled.

In Popular Culture

In the 1993 classic science fiction adventure film, Jurassic Park, Metriacanthosaurus' embryo can be seen.
