Shark tooth ID - Naples Beach, Florida


Recommended Posts

NJRedhead

My 11 year old found this on Naples Beach in Florida, and are trying to identify the type and approximate age. I can’t seem to find anything definitive- I’m guessing an extinct white shark, but would love some expert eyes. Thank you- this is more exciting than the masks, medical waste and needles floating to shore on our NJ beaches currently. :(

Welcome to the Forum. :)

 

There aren't any serrations, so not a Great White. Looks more like a Mako Shark tooth. 

Can't help with age, but one of our other tooth experts may be able to chime in.

Here is a Florida Great White,  followed by a Florida Mako.  One major difference.2015Mar3rdGreatWhite.thumb.jpg.33e7b8dafd402f3fd0c916702e6a32e0.jpgBlueMako2.jpg.c752f9ba43e6586ed2244951bff6d652.jpg

Hello. Your tooth is Carcharodon hastalis

 

It is often called Giant mako (Isurus hastalis, Cosmopolitidus hastalis), but this is something of a misnomer as it is closer related to white sharks.
