Shark Teeth Id

Hey everyone, I was curious to see if anyone could help give us a definite ID on these teeth. We believe there are some tiger, snaggle tooth, hammerhead and great white.

Last one looks like dolphin or porpoise, but Boesse will know what it belongs too, down to the individuals cousin. ;)

It looks like you have a Chub/Meg transitional tooth as there are signs of a slight cusp (though could be a young Meg as well). The tooth below it does not appear to be serrated and looks to be a Isurus Hastalis (Mako). As for the smaller teeth you have four Hemipristis Serra (Snaggle Tooth), two or three Galeocredo Contortus (Tiger), and two or three Carcharhinus sp. (these are a little hard to narrow down to one species).

Your shark teeth are .. top left Carcharocles chubutensis in my opinion but could be C. megalodon. Bottom left Isurus hastalis (extinct giant mako). Center row top, second and fourth Hemipristis serra (snaggletooth), third and fifth Physogaleus contortus ( extinct tiger like shark) 6th or bottom one looks like some type of Carcharhinus species. The right row top is a dolphin tooth next another snaggletooth, third looks like another type of Carcharhinus specie and the bottm not sure, broken and not a good pic of it. Your dolphin tooth probably cannot be ID any further than Odontocete sp.

Jay, This tooth has been moved from Galeocerdo to Physogaleus

Hi,

I think, top left also could be an Angustidens. Possibly... I have got a similar tooth from Summerville, identified as a Chubutensis or an Angustidens. A friend prefers Angustidens.

Greetings from Germany,

Bernd

Thanks Don! I'm always a little hesitant to leave Genus/Species as I'm still learning, but wanted to give it a shot. I also believe the top to be a Chub, but because others might make an argument for juvenile Meg or transitional species, I included that option as well. Though after re-reading what I wrote, I did not do a very good job of conveying that.

Fangirl,

Nice finds. I like the lighter colors, which would come from land (versus river) finds where I hunt in SW Florida.

Here is a link that will help you ID Florida fossil shark teeth. http://www.buriedtreasurefossils.com/Florida_Fossil_Shark_Teeth.htm.%C2'> I think that a possible ID for the tooth 2nd from the bottom on the right is Lemon Shark. You can use the link to compare. SS

Thank you so much everyone for all your help!! Here are a few more pictures of the small one with a root. I cannot thank everyone enough for everything.

I'm not sure about this, but the Carcharhinus tooth on the right, second from bottom, looks like C. brachyurus to me. I'd be interested to hear other opinions about it.

Hi,

a question of interest:

Where did you find the teeth? All at the same location?

Because of the Hemis and the Tigers I guess Florida (Gainesville?) or South Carolina (Cooper River?).
