I think that first tooth is a C. chubutensis, not C. angustiden. Nice finds!

Nice finds! I can't make heads or tails (literally, lol) of any of the bones we found on our Aurora trip. I certainly didn't finds any verts that were recognizable to me! You got some nice teeth as well. I found a few hemis but none are as nice as yours! Thanks for sharing.

Nice finds! Congrats

Thanks. I do not have much idea about how to separate a chubutensis from an angustiden... I heard the it should be about the separation between cusp and blade. No sure...

Thank you Lissa. When I found something I can't ID, I would bring it to the museum across the street and ask Judy (the lady at the desk of the museum store) or George (he sometimes can be found in the education center, other side of the crossing). They are very nice people and can often give useful references.

Any Carcharocles tooth coming out of Lee Creek material spans Miocene to Pliocene. Angustiden is an Oligocene species, that is the easiest way to differentiate. If you found one out of context, the difference would be the cusps. The cusps on C. chubutensis are not as pronounced as Angustiden.

It's a really nice find! I have yet to find one out of Lee Creek.
