Ceratosaurus nascornis tooth

[Pterygotus]

I recently saw a ceratosaurus nascornis tooth for sale which is described as this: Very Rare 3.5 cm Kimmeridgian, Late Jurassic Ceratosaur Theropod Dinosaur Tooth from the Morrison Formation, Colorado, USA. How does it look?

From these pictures only we can't know if this is a tooth if Ceratosaurus nasicornis. We need the denticle density on both carinae and we need a picture of the mesial carina.  There were a number of Big Theropod present in the Morrison formation and they are not easy to distinguish. Looks like a pretty nice tooth.

On a Ceratosaurus its also necessary to verify the CBR so we will also need the width and length at the base.
