Possible Crinoid - Mississippian - Missouri

[KimboSlice]

Can anyone confirm this for me? I believe it to be a top view of part of a Crinoid. It was found in a creek bed in Boone County, MO. I believe it to be from the Mississippian Era. It looks to me to be two of the arms laying down, as if you were looking at the Crinoid from the top. Am I accurate in this? It is super small, at maybe 1/4 of an inch big at the opening, though it goes maybe an inch deep. These are the clearest photos I could get of it, as it’s dark in there, and it’s so small. The opening measures 1/8th of an inch tall. It is 1/4th of an inch wide, and from the top of the opening to the bottom, crystallized circle part, it measures 1/2 an inch.

I wanted to add specific measurements for the fossil in question,

Can you get some different angles?

Unfortunately, I don’t think so. Let me try really quick!

This is about as different as it’s gonna get, I think, which is simply natural lighting. The opening measures 1/8th of an inch tall. It is 1/4th of an inch wide, and from the top of the opening to the bottom, crystallized circle part, it measures 1/2 an inch.

It looks as if it could be a weathered section through a crinoid columnal. (These come in a wide range of sizes, up to well over an inch in diameter.)

Oh, you may be right!! Thank you for your input!!

I agree. Crinoid stem cross section
