Some shark teeth ID

[indominus rex]

Today, my package arrived. A pile of 1000 shark teeth have arrived and there are some Megalodon teeth and some Makos and Angustiden and some tiger shark teeth. But I have a few I am not sure about. Is this a Megalodon tooth? I have no information about where these are found but could this be a Angustiden or even a chubutensis?

Maybe @Troodon or @Al Dente would know if that thooth is from a megalodon.

The person who sent them to you don't know where they come from ?

[Troodon]

Definitely not a Megalodon and could be a Angustiden depending on the age of the deposits it was found.

Yes, one of the two.

As Troodon said, this tooth could be O. angustidens or chubutensis. It would depend on the age of the sediments it was found in. It is always best to make sure a seller has good stratigraphy information about where a fossil they are selling was found. That is the only way a good educated guess can be made of the species.

I’d say it’s a chub. The cusps seem sufficiently fused, maybe a older one (geologically speaking). Where chub begins and angy ends is kind of muddy for me, and I think for most. I think morphology not date should be the main differentiation between species (or chronospecies)

i would lean angustidens. whhere did you get 1000 teeth lol

[indominus rex]

Wow thanks, I wasn't actually expecting Chubutensis to be a possibility. The seller only said these were from USA so unfortunately I don't know where. But if I had to guess I would say they are from Summerville. Thanks for all the feedback. And here is a photo of all the teeth

[Al Dente]

The color and species of the teeth look very similar to teeth coming from the reject piles from the Lee Creek mine. That would make most of the teeth mid Miocene in age.

I have also found this tooth in the pile and I was wondering if it could be a Benedini.

[MeargleSchmeargl]

That's probably a Carcharocles Angustiden tooth. Nice one, too! 

[Miocene_Mason]

That last tooth you posted is not a parotodus, looks more like a worn Mako maybe? Isurus desori probably.
