espeton Posted January 17, 2017 Share Posted January 17, 2017 Hi everyone, One of my friend just found this tooth in Brownie Beach (Calvert Cliff, MD). It looks like a worn Mako but it has serrations, so I am toward a Meg tooth. Any other suggestions? Thanks Link to comment Share on other sites More sharing options...
FossilDudeCO Posted January 17, 2017 Share Posted January 17, 2017 I am not very good at shark teeth, but it could be a pathological mako. Let's try @ynot Link to comment Share on other sites More sharing options...
Doctor Mud Posted January 17, 2017 Share Posted January 17, 2017 Definitely Mako. It's hard to say from the pics but the "serrations" are either damage or a pathology. They are not regular enough for meg serrations. Link to comment Share on other sites More sharing options...
gavialboy Posted January 17, 2017 Share Posted January 17, 2017 it is not the right age but it looks oddly like a paleocarcharodon tooth maybe from a lag layer. Link to comment Share on other sites More sharing options...

Sometimes Brownies produces some oddballs. Teeth from other time periods do occasionally show up. I like Trilo-butts and I cannot lie. Link to comment Share on other sites More sharing options...
sixgill pete Posted January 17, 2017 Share Posted January 17, 2017 Definitely not a meg. I agree it looks very much like a Paleocacharodon.

Ramon Posted January 17, 2017 Share Posted January 17, 2017 The serrations are to wide in comparison with the tooth to be megalodon. It must be some other shark.

ajnthony Posted January 17, 2017 Share Posted January 17, 2017 I agree with a worn mako. Here is a meg we found today in Calvert at the cliffs for comparison. I hope it helps. Link to comment Share on other sites More sharing options...
ynot Posted January 17, 2017 Share Posted January 17, 2017 Mako (white) shark teeth do not have serrations. Could be a C. hastalis transitional tooth. (?)

espeton Posted January 17, 2017 Author Share Posted January 17, 2017 My first thought was also a Paleocacharodon Orientalis, but if finding one in the Potomac is very difficult (I did not find any yet in about 50 trips) can you imagine how hard can be to find it in the Calvert Cliffs? By the way, this is the second trip of my friend to Brownie Beach Link to comment Share on other sites More sharing options...

Tony That thought also passed through my mind looking at it. I'm leaning towards no though. The transition goes from faint serrations to proper serrations and I don't recall such well defined "ragged" serrations in the transition. If we could have a clear close shot, that would help. From what I can see I'm leaning towards a damaged mako. Link to comment Share on other sites More sharing options...
