Ceratosaurus nasicornis

Holotype specimen, USNM 4735, described by Gilmore (1920). I had some time left and thought I’d make a late contribution to the challenge by :iconijreid:.

Do you have any data on how long Ceratosaurus' tooth crowns were?

These are the data from Smith et al. 2005 (All measurements in mm, crown heights in bold–possibly slight underestimates, but not much based on theropods’ closest thecodont relatives):

(you should be able to copy and import that into the statistics software of your choice, otherwise the paper is freely available at the link I posted below).

Specimen 5278 is the C. "dentisulcatus" holotype, not sure whether the other one is among the specimens that likely belong the same individual, but it seems possible.

I'd check Smith et al.'s 2005 tooth morphometrics paper, it contained some measurements but not sure how many. I can look it up later.
