Unidentified Virginia vertebrate fossils

[Ned the naturalist]

These are some fossils that I couldn't quite identify while out looking around an area of land in the Nottoway river drainage today. The first appears to be some sort of bone, my guess is a vertebra potentially belonging to a crocodile, though I am very new to this and am quite possibly incorrect in this guess

 



 

 

 

Next up is a decent sized fragment of a shark tooth that I initially thought to be a young megalodon, but then wasn't quite so sure after noting the presence of what appears to be a slightly weathered cusp on the side of the tooth that is still present, alongside the fact that the tooth appears to have a slight curvature to it

Any insight is well appreciated, thanks!

Sorry, but I don't recognize either bone or tooth in these photos.

The second item does look like an extremely water worn fragment of a meg, to me. 

The first item requires additional photos. 

Please see this post.

Okay, I see bone texture in the first one. I'm afraid it may be too fragmentary to identify though.

The last one is a well worn meg tooth. Compare the size of the root to the rest of the tooth...that would have been a good sized tooth.

 

See the root to overall size ratio below.
