Raff Posted January 7, 2011 Share Posted January 7, 2011 (edited) Hi, I bought these teeth on Ebay, they come from Venice (Florida), the seller said that are represented a variety of species: lemon, bull, dusky, sand tiger, snaggletooth (hemipristis serra?), mako and tiger shark. Can anybody help me, if is it possible specifying both common and scientific name ? Thanks Edited January 7, 2011 by Raff Link to comment Share on other sites More sharing options...
cowsharks Posted January 7, 2011 Share Posted January 7, 2011 (edited) Hi, I bought these teeth on Ebay, they come from Venice (Florida), the seller said that are represented a variety of species: lemon, bull, dusky, sand tiger, snaggletooth (hemipristis serra?), mako and tiger shark. Can anybody help me, if is it possible specifying both common and scientific name ? Thanks Hi. The teeth that you have here are all very worn, so coming up with a positive ID on some of them is very difficult, especially on the Carcharhinid species. I took your original picture and added a legend with some possible ID's for each tooth. I'm fairly positive of the ID's, but for the Carcharhinus teeth, I would recommend that you try to use www.elasmo.com and search under Lee Creek (sharks II). Even when the teeth are in perfect condition, it is difficult to differentiate between the subtle differences in the many carcharhinus species. I think most of the carcharhinus teeth you have are "1a" Copper shark teeth. Using elasmo and the teeth in hand, you might be better suited to narrowing down the teeth to a particular shark. Most of the carchinus teeth you have here are "upper jaw" teeth. Sometimes lower carcharhinus teeth can loook very similar to lemon shark teeth, the difference being that lemon shark teeth do not have fine serrations on the crown. There are no mako's, tiger's, or hemipristis (snaggletooth) shark teeth in your group. You can use elasmo (sharks I and II) to see these other types of sharks teeth. Hope this helps. Daryl.

Raff Posted January 7, 2011 Author Share Posted January 7, 2011 Thank you very much for the answer, I easily get confused with common name because in Italy we call bull shark the sand tiger shark (i.e. Odantaspis taurus) not C. leucas (sometimes we call it Zambesi shark) and the only "tiger" shark is Galeocerdo !
