Skull cast of Marshosaurus at the Natural History Museum of Utah, Salt Lake City, Utah
is a tooth of one of the rarest theropods out of the Morrison Formation, Marshosaurus. This 1.54" long tooth was collected in the summer of 2014 from the Skull Creek Quarry, East of Dinosaur, CO. Only a few Marshosaurus teeth have been recovered out of probably thousands to teeth found at the quarry over the years.

This larger than most of the Marshasaurus teeth I've seen but does have some restoration work done to it. A section of enamel at the base of the tooth has been restored, as has the last 2mm or so of the tip and there is a repaired crack about 1/3 of the way down from the tip.

Marshosaurus is a genus of medium-sized Megalosaur from the Late Jurassic, Morrison Formation. In 2010, Gregory S. Paul estimated its length at 4.5 meters (15 feet) and its weight at 200 kilograms (440 pounds). It is one of the rarer theropods in the Morrison Formation: only a single partial specimen has ever been recovered.
