Crinoid ID, Agaricocrinus pracursor?

[Collector9658]

Today I went through some piles of weathering Fern Glen limestone I have outside, and I found the cutest little calyx. First thought was it was a chunk of stem, but after chipping it out of the rock that was definitely not the case. I compared it to some literature I had on hand, and believe it is small Agaricocrinus pracursor crinoid calyx. I Would like some second opinions.

Unfortunately I don't have an air abbraider to clean this calyx further and it being so small as well as ironstained makes it tough to photograph well with my old phone, so I will add a couple more photos than usual.

Thanks as always. -Jay
