Metriacanthosaurus, which means “moderately-spined lizard”, is a genus metriacanthosaurid dinosaur from the Oxford Clay in England. It dates back to the Late Jurassic period (lower Oxfordian) approximately 160 million years ago.

Friedrich von Huene, a German paleontologist, wrote a paper in 1923 on Jurassic-Cretaceous European carnivorous dinos from Saurischia. He examined OUM J.12144, which included a broken hip, a leg bone and part of a spine, and assigned it to Megalosaurus parkeri, a new species. W. Parker, who had found the fossils at Weymouth’s Jordan Cliff in the nineteenth century, was the name of the specific species. These bones are from the Oxford Clay Formation which dates back to the Upper Jurassic.

Von Huene, however, concluded that it was an Altispinax species, A. parkeri, in 1932.

Alick Walker, a scientist, decided that these fossils were too distinct from Altispinax because they did not have long vertebral spines. He named the new genus Metriacanthosaurus in 1964. The Greek words metrikos (moderate) and akantha (spine) are the basis of the generic name. Metriacanthosaurus’ name derives from its vertebrae which are higher than most carnosaurs like Allosaurus but lower than high-spined dinosaurs such as Acrocanthosaurus.

Metriacanthosaurus, a medium-sized theropod of average size, had a femur that measured 80 cm (31 inches). Gregory S. Paul estimated the weight of Metriacanthosaurus at 1 tonne (11.1 short tons) in 1988. Thomas Holtz stated that the length was 8 meters (26.2 feet). Metriacanthosaurus is named after the height of the neural spines. These are not too tall for theropods. They are 1.5 times taller than the centrum and they look similar to Megalosaurus, Sinraptor and Ceratosaurus.
