Miscellaneous Bones

[Spr]

All found along the beaches anywhere between Onslow Beach and Holden Beach, North Carolina. If you would like more pictures of anything please let me know, thanks. The shark tooth is strange to me because I thought it was a fragment but the serrations on both edges make it seem otherwise like a newly grown tooth? I have plenty of shark teeth and no problem identifying them but this one stumps me. As far as number three goes, I thought it was a piece of turtle shell but my geology professor thought it may be a very worn tooth, however he wasn’t sure.

The shark tooth looks like a crow shark, 3 and 5 look like turtle.  6  appears to be iron stone, not a fossil.  The bone pieces wold be helped with multi sided photos

The "worn tooth" looks like a piece of softshell turtle plastron to me; it has that dimpled pattern that is diagnostic to them.

The worn tooth in my opinion doesn’t look like turtle to me. It looks like a mammoth tooth just worn down over time.

#1 looks like a heavily worn mammal vertebra

#3 softshell turtle

$4 is a vertebra, maybe from a ray (it's a bit dark)

#5 turtle, but the texture doesn't look like the Trionychid soft shell turtles

#6 just a rock

Can you get a closer picture of 2? To me it looks like a posterior megalodon tooth.

Thanks for the extra shots, I still agree with posterior meg tooth.

Team Squalicorax for the shark tooth (likely S. pristodontus). Cretaceous fossils can be found nearby. NC locals may say for sure whether Cretaceous fossil can be found at the beach. Meg posteriors are usually fat - especially the root. 

 

Note that Squalicorax has an exaggerated semi-circular mesial edge near the base of the crown:

Here are a couple of topics with nice examples of posterior megs:

I agree the tooth is Squalicorax. The vert (#4) appears to be ray. Do you know which beach these were found on? Different beaches have different aged fossils.

I see what you are saying @ThePhysicist, Squalicorax, does match the shape pretty well, you and @sixgill pete know way more about shark teeth than I so @Spr listen to them.

Yeah so, #’s 1,2,5,7 came from Holden Beach I would guess from the dredging taking place currently as I found them all within a couple hundred meters of the active worksite of that makes any difference. #’s 3,6,8 were from Onslow Beach and number 4 was the south end of Kure Beach at the edge of Fort Fishers starting point.

Haha, anyone on this forum knows much more than me so I’m thankful for any information : )
