Purse state weird bone fossil id

[Rexofspades]

here are some stuff that I found in the aquia formation over the weekend. 

 

this button is weird to me, my gut tells me it might be a vert, but it could also be a fish tooth perhaps?

 

 

this is a weird one, it looks like a Galeocerdo tiger shark, but i havent read anything of these existing at the Aquia formation, much less finding them at purse.

 

 

bone fragments?  would it be possible to tell if its reptile bone?

 

this bone is interesting because it has some underside of its surface still intact. it almost reminds me of a skull fragment maybe?

 

 

lastly, a nice lady gave me this piece, whats funny is that she found it two minutes after I told her I was looking for crocodile teeth.

It looks like Pachygaleus. The first fossil is most likely a fish tooth.

I think they are fairly common. Have you looked at www.elasmo.com? Click on their faunas page and then select Aquia.

The last item looks like a bit of fish bone, but I don't think much more can be said about it.

No real identifying features.
