Marshosaurus bicentesimus - DinoFan83 - 04-02-2021
Marshosaurus is a genus of carnivorous dinosaur belonging to either the Allosauroidea or the Megalosauroidea known from the Late Jurassic of the US states Utah and Colorado.
It was a medium sized theropod from known fossils, with specimens discovered so far suggesting a size range of 4.5-5.9 meters and 200-450 kg. The holotype ilium can be estimated at 44.2 centimeters when complete based on comparisons with its more complete relative Eustreptospondylus. More specimens are known, such as the paratypes which consist of more pelvic material.
Known skull material indicates Marshosaurus had a large skull for its size, with the largest discovered skulls being 60 cm long and the largest specimens possibly having skulls about 78.7 cm long. Its forelimbs were large, heavily-muscled, and massively built relative to its size, being tipped with especially large claws. The hindlimbs were also very robustly constructed as well as proportionally long, suggesting an animal evolved for both strength and speed to capture prey.
Marshosaurus lived alongside many more famous and larger dinosaur species, such as Allosaurus, Torvosaurus, Apatosaurus, Stegosaurus, and Camptosaurus.
