SawTooth Posted November 11, 2022 Share Posted November 11, 2022 Ok so I'm a little late on this post. This summer I took a trip up to south Carolina and got some pretty nice finds.First of all I got my largest angustiden, which was a miracle that the pieces were still close together, I found it In a creek surface hunting and found both pieces, which seems nearly impossible.Along with this I got my largest desiri mako.I also got this strange tooth which at first I thought was a sand tiger but 1. I don't find many of those in creeks 2. The root seems pretty flat, not the general V-shape normally found in sand tigers. 3. the blade seems wider than it should be. Can I have your opinions on this one, you would know better than me, thanks! 1 Link to comment Share on other sites More sharing options...
TRout Posted November 11, 2022 Share Posted November 11, 2022 Nice teeth! That split angustiden is very pretty. As for that last tooth, I’m not exactly sure what it is, but I agree that it doesn’t look quite right for a sand tiger (I’d expect the cusplets to be pointier). I’ve heard that lateral teeth of juvenile isurus can sometimes have cusplets. That could be a possible ID for the tooth but hopefully someone with more knowledge on shark teeth from this area could chime in with their opinions. 1 Link to comment Share on other sites More sharing options...
Fin Lover Posted November 11, 2022 Share Posted November 11, 2022 (edited) Definitely not a sand tiger. Isurus oxyrinchus and I. retroflexus do have cusplets. Possibly Isurus or lower lateral hastalis, but wait for someone else to respond.

After looking at pictures of those two, the Isurus retroflexus does look very similar, at least some of the images, but I think I will follow your advice and wait a bit.

Fin Lover Posted November 12, 2022 Share Posted November 12, 2022 Here is one I found in the Summerville area. They have an enamel "shelf" that you can see on the second picture. 1 Fin Lover My favorite things about fossil hunting: getting out of my own head, getting into nature and, if I’m lucky, finding some cool souvenirs.

SawTooth Posted November 12, 2022 Author Share Posted November 12, 2022 So it seems everyone is thinking mako of some sort on this one? Link to comment Share on other sites More sharing options...
