Shark Tooth ID Please

[Bails]

Hey all,

 

I just got back from a quick shark tooth hunt in Charleston, SC after a day of work and was pretty excited when I stumbled upon this tooth. It is about an inch long.Can someone help me ID it? Parotodus benedini? Alopias grandis? Something else? 

Happy to post additional pictures if needed.

 

Thanks!!

Only american members know the size of your coin ! Please give us the size in inch or cm. Or put a scale on the pics.

@Coco in the original post I noted it was an inch long.

My money is on Alopias grandis

Thanks @BellamyBlake! I have found other Alopias grandis teeth at this same spot. I didn’t realize the Alopias grandis crown got that long.

I think you might lose your money.  Don't Alopias usually have broader crowns? I suspect it is Parotodus, but I'm not great at IDing them. 

 

@WhodamanHD Can you provide some ID help? Thanks.

The root does not seem massive enough to me for Paratodus. I would lean more towards A. Grandis, but that just does not seem quite either to me.

That tooth looks familiar.  I puzzled over this one:

Haha I myself get confused between those two; I went with Alopias because the root didn't seem large enough for Paratodus, similar reasoning to @sixgill pete

I’d guess paratodus benedini, based on the root shape, being a lot broader root and a longer blade, the shape overall just suggests it’s a bene to me.

Hi Bails,

 

Can you give us a profile shot so we can clearly see the root thickness.  I wouldn't usually ask for an angled view also but can you give us a view of the bourlette area from the direction of the tip at the crown-root boundary.

 

It does look like Harry's Parotodus.  It's a more slender morphology you see in Late Eocene to Late Oligocene Parotodus teeth but the root still has a distinct lingual protuberance.  I have one like Harry's from Ridgeville, SC (where a lot of Pliocene teeth are found but sometimes also some Oligocene).

If you do a Google search of Oligocene Parotodus, you will see a lot of similar teeth from South Carolina. There are also narrow Oligocene Parotodus from Belgium. Here’s a photo from my copy of Leriche’s 1910 “Les poissons Oligocene de la Belgique”.

In my opinion the crown is far to compressed to be an Alopias grandis. Looks classic late oligocene/early Miocene Parotodus benedeni to me, in great condition. Parotodus is actually fairly variable throughout its temporal range, Mid-miocene to Pliocene teeth tend towards the robust side, while these are fairly gracile. Late oligocene sometimes still has cusps.

A huge thank you to everyone on helping me out with an ID! This place is awesome! 
 

Pretty excited about this ID!

Pretty wild, today I found another P. benedini in the same exact spot at the same site I found the one in the original post above. 

Here is a picture of it in my display case next to the one in the original post.
