BellamyBlake Posted July 11, 2020 Share Posted July 11, 2020 Hi everyone, I have here a tooth being sold. The merchant identifies it as Carcharodon hastalis. Based on confirmed photos of Carcharodon hastalis, I have many doubts. My main reasoning is that the angle between the start of the root and the rest of the tooth seems far too steep. Carcharodon hastalis, to me, seems to have rather straight edges; this one appears way too curved. This is why I believe the merchant may have misidentified their tooth. It's 19 mm long, and supposedly found in Chile. I'd appreciate any confirmation, and apologies as these are the only two photos provided by the merchant.

sagacious Posted July 12, 2020 Share Posted July 12, 2020 The asymmetry of the root lobes assists in in identifying this tooth. To me this is more likely an upper lateral Isurus oxyrhinchus tooth. 1 Link to comment Share on other sites More sharing options...

Here are a couple photos I took of a 22mm upper lateral I oxyrhinchus tooth for comparison. It looks to me to be the same position and species as the tooth for sale. 1 Link to comment Share on other sites More sharing options...
