sf_troop302 Posted May 18, 2018 Share Posted May 18, 2018 Could someone help me identify what sharks these came from? These are the four best we found aside from a sand tiger my son found. All together three of us walked away with over 130 teeth in about 3.5 hours. The scale in the pics is mm. These were found near the Venice Beach, FL fishing pier.

The Jersey Devil Posted May 18, 2018 Share Posted May 18, 2018 All of these are Carcharhinus sp. teeth, except for the second tooth in the second pic which is a bit too abraded to tell for sure, although it is likely a Carcharhinus as well. “You must take your opponent into a deep dark forest where 2+2=5, and the path leading out is only wide enough for one.” ― Mikhail Tal Link to comment Share on other sites More sharing options...
sixgill pete Posted May 18, 2018 Share Posted May 18, 2018 The bottom tooth in pic 1 and pic 4 looks like a well water worn O. megalodon. The top tooth in those pics and the top tooth in pics 2 and 3 look like Carcharhinus sp. Possibly C leucus or C. Obscurus (bull or dusky shak) the other tooth is way to damaged to be sure but gives me a meg vibe.

I think it is another Carcharhinus because of the sinusoid outline of the basal margin. The other worn tooth is either a Meg or a Carcharhinus I guess. 1 “You must take your opponent into a deep dark forest where 2+2=5, and the path leading out is only wide enough for one.” ― Mikhail Tal Link to comment Share on other sites More sharing options...

Fossil'n'Roll Posted May 18, 2018 Share Posted May 18, 2018 (edited) I agree these are likely all Carcharhinus sp. Could you take a picture of the other side of the bottom tooth in the first picture? That should clear up the megalodon vs Carcharhinus debate for that tooth. edit: I should be more observant too. Oops. Also, @sixgill pete, the scale is cm not inches. Here are some Carcharhinus teeth (not mine): And here are a few megalodon teeth (also not mine): Edited May 18, 2018 by Fossil'n'Roll 1 Link to comment Share on other sites More sharing options...
Jazfossilator Posted May 18, 2018 Share Posted May 18, 2018 I agree that these are probably all Carcharhinus sp., here’s one of my own that looks very similar to the tooth up for debate. Link to comment Share on other sites More sharing options...

I think it looks a bit more stout because of the broken edge and wear; the "bourlette" seems like a wear pattern to me. A <2 cm anterior Meg would be a bit small, even though they do get small. It is also likely that it is a Carcharhinus since all the other teeth are Carcharhinus. “You must take your opponent into a deep dark forest where 2+2=5, and the path leading out is only wide enough for one.” ― Mikhail Tal Link to comment Share on other sites More sharing options...

The Jersey Devil Posted May 20, 2018 Share Posted May 20, 2018 The upper left tooth is a Carcharodon hastalis. The lower left tooth is an upper anterior Hemipristis serra.
