Marshosaurus was a medium-sized meat-eater that lived near the end of the Jurassic Period. It was discovered in the famous Cleveland-Lloyd Dinosaur Quarry, a very famous site that has produced many Allosaurus specimens. Since this dinosaur seemed to have lived at the same time as the larger Allosaurus, it probably hunted different prey and did not compete for the same food as the larger dinosaur. Marshosaurus would rarely have won a fight with an Allosaurus!

Not enough of Marshosaurus has been uncovered to authoritatively assign it to a specific family. It has been suggested that it may be a ceratosaur or more generically, a carnosaur.
