Meganeura Posted April 7, 2023 Share Posted April 7, 2023 Found this tooth in my micro mix - it’s about 1-1.5mm long. Has a cusp. Is unbroken (Except maybe missing a cusp on the other side??) but looks like symphyseal lemon shark teeth roots I’ve seen… got no idea! @Al Dente @hemipristis @MarcoSr 1 Fossils? I dig it.

I would guess some type of Carcharhinus. 1 Link to comment Share on other sites More sharing options...

And very strange too. What a weird evolutionary trait, to have a single cusp on one side of a tooth... Fossils? I dig it. Link to comment Share on other sites More sharing options...
