Ramon Posted February 5, 2017 Share Posted February 5, 2017 Hi!!! I have this shark tooth which was found in Florida. It is triangular like a mako or a great white shark tooth. But it's too small only about 1.5 cm!!! It has no serrations or at least no signs of them ( maybe a little worn down).

ynot Posted February 5, 2017 Share Posted February 5, 2017 That seems to be about the lower limit. White sharks that are smaller than that (excluding posterior teeth.) seem to be more peg like and match the lower teeth more. 1 Darwin said: " Man sprang from monkeys."

calhounensis Posted February 5, 2017 Share Posted February 5, 2017 Looks like a lemon shark missing the majority of the root, not a white shark. Link to comment Share on other sites More sharing options...
calhounensis Posted February 5, 2017 Share Posted February 5, 2017 Negaprion brevirostris, I believe may be the correct name. I've found some pretty large examples of this shark off Venice. Large enough to be confused with a white shark. Link to comment Share on other sites More sharing options...

calhounensis Posted February 5, 2017 Share Posted February 5, 2017 Not many features to go off here.. It's water worn and almost completely missing the roots. What feature here makes it a C. hastalis? Edit: Sharks aren't my area, so I can't give a breakdown of minute differences. I have found enough of these small beat up sharks teeth. In my collection I would call it a lemon. Link to comment Share on other sites More sharing options...
calhounensis Posted February 5, 2017 Share Posted February 5, 2017 Here's a poor quality photo of some Venice teeth. There's a nickel, a rootless white shark tooth, a bunch of lemons, sand tigers, and bull shark teeth. 1 Link to comment Share on other sites More sharing options...

What feature here makes it a C. hastalis? The general shape, The root/crown border shape. It just looks like a lot of the smaller C. hastalis teeth I have found. Have not seen any Negaprion brevirostris, to My knowledge, so I have no reference to compare them. Most of My digging is in California, and those are not listed as present in the formations I have dug. 1 Darwin said: " Man sprang from monkeys."

ynot Posted February 5, 2017 Share Posted February 5, 2017 Also the width to length looks more hastalis to Me. Darwin said: " Man sprang from monkeys."

Ramon Posted February 5, 2017 Author Share Posted February 5, 2017 Mine looks exactly like your white shark tooth!!! But is it a great white or a mako because I see no serrations???

calhounensis Posted February 5, 2017 Share Posted February 5, 2017 I'll take one last stab at this before I give up. Tried to duplicate your picture as best I could. Even found the right year nickel. 1 Link to comment Share on other sites More sharing options...

calhounensis Posted February 5, 2017 Share Posted February 5, 2017 Perhaps some measurements on width would be helpful from Ramon. Seeing as paper isn't the best measuring tool and we were never told if it was wide or college ruled paper. Link to comment Share on other sites More sharing options...
ynot Posted February 5, 2017 Share Posted February 5, 2017 A side view would help also. Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

sixgill pete Posted February 5, 2017 Share Posted February 5, 2017 I do not think this tooth is a lemon shark, but I am not convinced on hastalis either. The fact that it is so water worn and missing most of the root makes it kind of tough to designate an ID to it. Sometimes a tooth cannot be ID'd positively. But lets see what some others opinions are.

PaleoRon Posted February 5, 2017 Share Posted February 5, 2017 My first impression was that it is the blade of a large Lemon shark. Link to comment Share on other sites More sharing options...

I agree with Don that the condition of this tooth makes a positive id very difficult. I had the same first impression as PaleoRon of a large Lemon shark crown. However, I wouldn't bet any money on that id. Marco Sr. 1 "Any day that you can fossil hunt is a great day."

Bandicoot Posted February 5, 2017 Share Posted February 5, 2017 My guess would be Isurus Retroflexus, I found many with the same curvature to the start of the root and the same general shape and curve. I'm not a shark person but that is my hunch. Again like most have stated, with out the root and the serrations it is rather difficult to ID this. The tricky thing about Makos is that they have a ton of different teeth in there head. 1 Link to comment Share on other sites More sharing options...
