Extinct Mako?? Shark tooth


kidafro

Recommended Posts

I recently acquired a shark tooth but I do not have a lot of expirience in this specific field and would like to ask what shark this comes from. I am certain it is from the Miocene period but I think it is a mako shark tooth.-Correct me if Im wrong. Pls*How much should I sell it for and how do I classify it

Poor picture with no scale. Hard to be sure what the tooth is.

 

The Fossil Forum does not do appraisals.

Can't tell from here. Take a closeup without your hand. Could be a hemi.

I can enlarge the picture without it blurring. I am 99.9% sure it is not Hemispristis. With most of the root missing I could only say it may be a mako, possibly I. desori. It could also be a sand tiger species. 

@kidafro do you know the location where it was found? This could help us more in determining what it could, but more importantly could not be. Saying it is from the Miocene is very world wide generic.

Yeah you're right. Not a hemi. Like you said it could be a sand tiger but don't sand tiger teeth have the little barbs on both sides of the root? I always get confused when the teeth come from various locations in the mouth.

Yes, but the wear on the tooth could have removed them.

The cusplets (barbs as you called them) can wear or break off pretty easily. Also, there are multiple species of extinct sand tigers. I've seen them both with and without cusplets and even some with multiple cusplets on the same side. Here is an example.

Yes sand tigers do have side cusps on there teeth. Some species on just some of their teeth others on all of them. Some sand tiger species have more than one side cusp on each side. Remember this tooth is very worn with a broken root. Often times sand tigers are found with the side cusps missing.
