✅ SOLVED What type of fossil?

[Bugzy99]

The fossil board is pretty quiet......I wanted to know what types of shells these were. Looks like 2 different shells, however, the one with a dot in the middle is most prominent. My only response was that someone thought it to but crinoid sections, but never found a photo that matched.

Found in northern Maine....thank you!

Crinoid incrustation from the 1700s with marginal sea limpets inbedded in its erpin surface, kidding no idea but looks old good door stop like the people who had a meteor for a door stop for 15 years
