Strange fossils in chert found in NY

Recommended Posts

Hi,

  I was driving along the NY State Thruway recently and stopped at several roadcuts in Devonian limestones. I picked up a big chunk of chert that had interesting fossils in it. I think they are crinoid column segments seen edge-on and end-on, but I'm not sure. They are all encased in chert and they are not CaCO3 (they don't fizz in HCl). Does anyone have any other ideas?

 

Thanks for any help,

Bob

After looking at them some more, and with your suggestions, I agree.
