Rikache Posted January 28, 2022 Share Posted January 28, 2022 Hi everyone! I recently acquired a collection of small fossil shark teeth from Jacksonville, Florida and was looking through all of them in order to identify them. This specific tooth really caught my eye since it didn't really match up with any of the identification resources I was using. From my understanding, megalodon teeth this small are very uncommon as only baby teeth and posterior teeth are this small, but the root, wide broulette, and blade look like they match a megalodon's tooth. Obviously though, this is just wishful thinking. I would greatly appreciate it if anyone could help me identify this tooth and possibly teach me how to identify teeth such as this one. Thank you!

Nanotyrannus35 Posted January 28, 2022 Share Posted January 28, 2022 Sorry, doesn't look like a megalodon tooth to me. Looks more like a tiger or bull shark tooth. 1 2 Enthusiastic Fossil Hunter Link to comment Share on other sites More sharing options...

Thank you! We all go thru the process of learning. Carcharhinus sp. includes Megalodon, Bull, and Dusky sharks. Differentiating is often triggered by minor variations. See that indentation into the upper lateral edge == Bull Shark, maybe dusky, but definitely not Meg. The indentation can be more/less pronounced. I would have to think a while if this small Meg could be so worn that I would think iy to be a Bull Shark.... Mostly a matter of finding a LOT of each.... that is a learning process to enjoy.

sixgill pete Posted January 29, 2022 Share Posted January 29, 2022 Also, please let me add. Using coins for scale is no good. Members not from the U.S. most likely have no idea of the size of a nickel. As we would have no idea of the size of a coin from their country. Use a ruler or give the measurement is the best. Preferably in mm or cm as that is the world standard. 2 1 Bulldozers and dirt Bulldozers and dirt behind the trailer, my desert Them red clay piles are heaven on earth I get my rocks off, bulldozers and dirt Patterson Hood; Drive-By Truckers May 2016 May 2012 Aug 2013, May 2016, Apr 2020 Oct 2022 Link to comment Share on other sites More sharing options...
digit Posted January 29, 2022 Share Posted January 29, 2022 Yup. Juvenile megs are very chucky with very small blades with coarse (for their size) serrations. The tooth in question has much too high a peak for a posterior meg. See Jack's excellent example above. Cheers. -Ken 1 Link to comment Share on other sites More sharing options...
