Description
Marshosaurus is a relatively small theropod dinosaur from the late jurassic Morrison formation. it's a obscure dino that doesn't get as much love as it's contemporaries which is a shame, because it was a very interesting animal in its own ways. Marshosaurus's skull was over 2 feet long or 60 cm in length.

the reconstruction above is based on a skull cast from the national history museum in Utah, and the photo referenced is from Fossil Crates.

The holotype, UMNH VP 6373, was found in a layer of the Brushy Basin Member of the Morrison Formation dating from the late Kimmeridgian, approximately 155 - 152 mya. It is a left ilium, or upper pelvis bone. The paratypes consisted of three bones: the ischia UMNH VP 6379 and UMNH VP 380 and the pubic bone UMNH VP 6387. Three ilia and six jaw fragments were provisionally referred. The material represents at least three individuals.
In 1991, Brooks Britt referred tail vertebrae from Colorado, because they resembled non-identified tail vertebrae fragments from the Cleveland-Lloyd Dinosaur Quarry.[4] In 1993 a partial skeleton, CMNH 21704, from the Dinosaur National Monument was referred because its dorsal neural spines resembled non-identified spines from the Cleveland-Lloyd Dinosaur Quarry.[5] This specimen was also the subject of a 1997 SVP
