Barasingha Posted May 1, 2017 Share Posted May 1, 2017 Both these teeth were found in a Miocene area. Can you please help me ID the type of shark tooth. It is 1 1/16" long on the longest side and 1" wide at the top. Can you confirm if the other is a dolphin tooth? It is 1 5/8" long on a straight line and 2 1/8" around the outside curve. Thanks in advance. Link to comment Share on other sites More sharing options...
Darktooth Posted May 1, 2017 Share Posted May 1, 2017 I think the sharktooth may be sandtiger with cusps water worn away. The other tooth does appear to be dolphin. I like Trilo-butts and I cannot lie. Link to comment Share on other sites More sharing options...
Barasingha Posted May 1, 2017 Author Share Posted May 1, 2017 Thanks. I thought sand tiger teeth were more narrow and didn't get this thick. Link to comment Share on other sites More sharing options...
Al Dente Posted May 1, 2017 Share Posted May 1, 2017 The shark tooth looks like a posterior I. retroflexus. The genus might be different now. Cappetta placed it into Anotodus retroflexus. The other tooth is odontocete. Link to comment Share on other sites More sharing options...

I thought the same thing until a forum member pointed out that there is a species of Sandtiger that has broad blades. I can't remember the species off hand. It is hard to make an id when part is missing. But I based my id looking at the root which to me looks more like a Sandtiger or atleast what I have seen firsthand. It very well could be mako.

Don, I agree as well. That other tooth is one of those archaic dolphins perhaps best identified as indeterminate odontocete as also noted by Al Dente.

Boesse Posted May 9, 2017 Share Posted May 9, 2017 Al Dente and Jess have it - indet odontocete. Possibly something like a "kentriodontid" dolphin. Link to comment Share on other sites More sharing options...
