0.7" Marshosaurus (?) Tooth from the Morrison Formation found in Moffat County, Colorado. After carefully studying this tooth I concluded this tooth is not Allosaurus and had a number of similarities to Marshosaurus teeth. However, due to the lack of serrations, I cannot be sure. The distal carinae appears to end 2/3 down the tooth which is further evidence But I cannot be sure of species. 150 Million Years Old.
