Fossil Shark Tooth ID?


Stealthynimrod

Recommended Posts

I found this mini tooth in the Miocene Brownie Beach/Bay Front park. It has a large root with very small serrations on the edges of it. I was wondering if this is a posterior megalodon tooth. Would be cool if it was

Thank you for replies in advance

Better pictures would be helpful in getting an ID. The pics are very blurry. Try taking the pictures from a longer distance then cropping them. They are blurry / out of focus.

The tooth is not to small to be a posterior meg. I have several as smaller and a few smaller. It does appear it could be.

This is as crisp as i could get it. There are micro serrations all the way around in case its not visible in the photo

it does appear to be. Try taking a picture of the other side of the tooth. The front side, or the labial or lip side.

Those views are great. It also helps to take pics of both sides of the tooth. Sometimes, especially on smaller teeth the front side is the better picture. With these pics, I say yes, it is a small posterior meg.

Hey! That's a cool meg. Great find!

It looks like it has two cusps. Does anyone if that's normal?

The tooth is in the direct lineage of a meg. It is a posterior chubutensis tooth versus megalodon evidenced by the cusplet in addition to the main cusp. Extreme posterior meg/chub teeth can be extremely small even when from fairly large adult sharks. Sometimes juvenile meg teeth can have cusplets but the site that you found the tooth is early Miocene where chubs are found.

With that thick root I figured it was likely a meg (and I still lean that way). When I saw the clearer photo with the single side cusp it got me wondering what an extreme posterior Tiger Shark tooth would look like. No great sources of posterior images of either species on the web but I wonder if Tiger might be a possibility? Still think it's likely a meg but that side cusp confuses me--of course we very rarely see megs with any side cusps down in South Florida though Jack (Shellseeker) has turned up a few.

Cool tooth.

Cheers.

Beautiful little posterior you've got there! : )

Every once in a great while it's not just a big rock down there!

Six inch teeth are a dime a dozen. Not everyone can find a meg that small. :D

Thanks for the info about the site Marc. I change my I.D. to C. chubutensis.

Here's my $1.20 and I'll let you know where to ship the gross of 6" megs. :P

Cheers.

Funny you should mention 6" megs, because my genetics team has just finished cloning the megalodon in that size. The only puzzle left is what color you may like and the style of goldfish bowl to put him in...
