Crinoid Calyx?

[BLT]

My husband found this in a middle Tennessee creek this morning. (Mississippian, St. Louis Limestone & Warsaw Limestone) Is it a type of fossilized crinoid calyx?

+1 for blastoid. That’s a lucky find.

Just a guess:Pentremites,based on statistical/stratigraphical considerations

Thanks! I just googled Pentremites. The images online actually look very similar to a small area of a fossil I posted for identification a day or two ago.
