Miocene Vertebrae? ID

[Johnny676767]

Collected #’s 1-3 at Brownies Beach, Maryland: Miocene, Calvert Formation and #4 in Matoaka, slightly younger formation (I believe). After trying to identify them, I think they are: 1: some type of bony fish, 2: Basking shark (I didn’t think it was a vertebrae until I saw this picture)- https://www.calvertmarinemuseum.com/334/Vertebrate-Fossils , 3: shark, 4: I am making a wild guess at a small crocodile. I am probably way off as this is my first shot at identifying these, so I thank you in advance for your insight.

I think they are all fish. Some just more broken up and partial bits.
