Various vertebrae

[I_gotta_rock]

Found all these at Matoaka Beach, Calvert Co. MD. Miocene marine environment, about 10 million years old. The first one looks very deformed. It is impossible to get a good shot of the center because of the curvature, but there is a pinhole of light shining through when you look at the ends

[Troodon]

First one might be partial sordfish vertebra

The next a Cetacean cervical vertebra

Bottom one possible tarpon
