Size and location @jpc I don’t have the exact locality but I’m good friends with the seller and can probably find out and get that information to you pretty quickly. But the size is 9 mm Link to comment Share on other sites More sharing options...

jpc Posted January 26, 2021 Share Posted January 26, 2021 I am looking through John Foster's book "Jurassic West" about the Morrison Fm. Seems most croc teeth form the Morrison are considered to be Goniopholis teeth. John is uncertain as to how many species of Goniopholis there are due to the incomplete nature of the specimens, and the idea that the minor differences in them might just be individual variation. There are a few other crocs from the Morrison, but they are pretty small and for a few of them the teeth are not even known. Recap: Goniopholis... most common Morrison croc. Right size for this tooth. Eutretauranosuchus... type specimen is a skull with no teeth. It looks like teeth are unknown "Fruitachmpsa"... size of a large house cat. Your tooth may be the right size, but this guy's teeth are slightly laterally compressed. Macelognathus... teeth unknown Hallopus skull and teeth unknown Hoplosuchus... puny; your tooth is way too big. I would be happy calling it Goniopholis sp. 3 Link to comment Share on other sites More sharing options...
