| '''Metricanthosaurus parkeri''' von Huene, 1923 |
Metriacanthosaurus (meaning "moderate-spined lizard") was a genus of sinraptorid dinosaur from Jurassic England. It ate other dinosaurs of its time and place, including Callovosaurus and various other small herbivores. In 1923 German Paleontologist von Huene wrote a paper on Jurassic and Cretaceous European carnivorous dinosaurs. In this paper, he examined a few specimens including an incomplete hip, a leg bone, and part of a backbone, and believed it was a new species of Megalosaurus.
In the 1960s, however, scientist Alick Walker decided these fossils were too different from Megalosaurus and named a new genus, Metricanthosaurus. Because so little is known about this dinosaur, any image is speculation, based on closely related carnivores. What is known about it is it is a carnivore distinct from any other.
Metricanthosaurus gets its name from its vertebrae, which are taller than typical carnosaurs, like Allosaurus, but smaller than other high-spined dinosaurs like Acrocanthosaurus.
[edit] In popular culture
- In the film version of Jurassic Park, one of the vials containing dinosaur DNA is labeled with the name Metriacanthosaurus, though the genus does not appear in the film.
