Post Oak Creek Texas Micro ID's - Croc Tooth?

Recommended Posts

Hello all! Sorting through some new Cretaceous Post Oak Creek matrix and have a few questions on what some of these might be. Thanks for any help! 

First is this round tooth....could it be croc? It doesn't have any striations, which I think croc would, but it is perfectly round so not a worn shark blade, I think. Anyways, any suggestions would be appreciated! 

1. Tooth? 5 mm

2.  This little piece...may not be identifiable as anything, but the surface texture is just interesting.  2mm

3. Possibly a denticle? Or tooth? I've found lots of sawfish teeth but this one doesn't seem to match anything else. 2mm

I believe this is Cantioscyllium or some other Ginglymostomatid (nurse shark)

1. Probably fish... very unlikely for there to be croc in POC as it was an open ocean environment

2. Ptychodus. Compare:

4. ya probably turtle
