Description[edit]
Metriacanthosaurus was a medium-sized theropod with a femur length of eighty centimetres. Gregory S. Paul in 1988 estimated its weight at a tonne.[5] Metriacanthosaurus was named for the height of its neural spines, which are actually not overly tall for theropods.[2] They are similar to other theropods such as Megalosaurus, Sinraptor, and Ceratosaurus in being 1.5 times the height of the centrum.[6]
