Switching gears here a bit. I have not had time to arrange these in some sort of sequence that resembles actual tooth positions (plus on a lot of them it's going to be very hard even

guessing a position).

 

A total of 203 Cretox teeth (erupted and unerupted), 17 vertebrae and 9 Squalicorax teeth from scavenging, all found in association.

 

The largest tooth in this set is 1.58" - 3.97cm. It's the second one from the left, third row from the bottom (left image).

Not sure of the identity of this little tooth. Maybe a Mobula loupianensis.

It is from the Round mountain silt.

scale is millimeters.

I do not know if somebody has commented on this with an ID suggestion and if this has already been put out there I apologize,  but could this be a Heterodontus tooth ?

You guys posted some fantastic teeth, thanks for showing!!

 

@Woopaul5 beautiful Notorynchus and I love the less common location for your Parotodus

@Untitled fantastic Macrorhizonodus, a true beauty .. also very nice Otodus and Serratolamna

 

wrt the Otodus here's the pdf: http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.874.7936&rep=rep1&type=pdf

 

and of course @fossilselachian I haven't been here in a while and haven't seen you in a while, great Parotodus from a great location!

Thank You for the suggestion, but the root is shaped wrong for an anterior heterodontus.

Actually the whole tooth has the wrong shape. In a heterodon the cusps are aligned with each other and have a rounded nature.

This tooth has the main cusp offset and the side cusps are elongated (almost ridges).

It is a Mobula tooth.  I don't think it would be M. loupianensis which was named after a site in France.  The teeth from Loupian are about the same age as Sharktooth Hill Bonebed teeth but it's asking a lot of a small ray species to colonize the French coast and maybe make it across the Atlantic to east coast of North America and then spread into the Pacific Ocean.  Yes, genera do that over time but it's usually the larger species that cross ocean basins.  Species of a particular smaller genus tend to live in a particular region with a related species living in another region.  Small sharks like Heterodontus and Squatina are found around the world because they started spreading around the world when the continents were closer together.  In their case Pangaea was just breaking up when they appeared and started to increase their range.

 

Anyway, I'd have to say it's possible it's the same species but it just seems unlikely given the distance and that's assuming the Loupian-named species did overlap in time as the STH form.
