Shark tooth ID?


flbug

Recommended Posts

Hello! I've been lurking these forums for ages and made this account just to see if you all can figure this one out. I've found this tooth many years ago when I was a kid off of Apollo Beach, Florida. I think the beach is actually closed now, but of the few teeth I have from there this one always stood out. I've only got this one picture, as I've recently moved and the little bugger has been packed away in storage. I found this pic again on my laptop and my curiosity about it was peaked once more. I'm only a novice collector but I'm thinking it's a disfigured bull shark tooth? It's about the size of a quarter and very bent in places, and the blade is very flat as if it's been compressed. Any ideas on it would be helpful!toothy.jpg.079f60a77d4fbfa32341566597792e62.jpg

Okay thanks! I can try to dig it out of the box it's in this weekend and see if that helps.

I think your original assumption was correct, it looks like a deformed bullshark tooth or some similar Carcharhinus species.

I would love to see a pic of the other side of this tooth, but right now I tend to agree with AlDente that it is a pathological (deformed) bull or some Carcharhinus species.

I agree with the others for pathological bull/dusky. 

 

But this part here is really weird for me. Does anyone know why/how the root deformed like this? I've never seen anything like it before...

Could it be chipped and not deformed...

This is not of the whaler or bull family of shark as those teeth have a deeper and finer tip to them. What you have could actually be a crow shark tooth of the order Lamniformes. The exact species is Squalicorax Pristodontus. The only reason I say that is because from what I have seen juvenile C. megalodon teeth tend to have a much wider enamel base and a shorter tip. This could still be a C. megalodon but in my inexperienced, eyeballing opinion it appears that you have a crow shark tooth. Here's a reference sheet:

I believe that crow shark is a cretaceous shark and the op's tooth is from  "found this tooth many years ago when I was a kid off of Apollo Beach, Florida".

No cretaceous deposits in Florida.

@ynot a lot could of happened between now and when crows went extinct in the late cretaceous, but based on that fact then it would seem more feasible that this is a C. megalodon. Good attention to detail. Now I'm beginning to question the origin of Lamniformes and what the first Lamniforme was. Perhaps now I'm even questioning the origin of sharks from the Silurian. :headscratch:

 

See: https://www.sharksider.com/timeline-shark-evolution/

 

Another interesting self-discovery tonight: C. megalodon could have possibly evolved from the Otodontidae family. :blink:

 

Here are some very tiny C. megalodon for reference:

It is both.

I did realize it was slightly chipped ;)

But if you look at it, and try to imagine how it would have looked like not chipped, it would make a really weird shape. So thanks Tony for pointing out that it is indeed deformed.

That's why it's called Otodus megalodon now ;) 

Carcharodon/Carcharocles megalodon are old names.
