Burlington crinoid calyx ID second opinion: Agaricocrinus planoconvexus?

[Jackson g]

For those of you familiar with crinoids of the Burlington Formation, (Mississippian) I would like to get a second opinion. This calyx is partial, but I believe there is enough present to confirm my guess for ID as Agaricocrinus planoconvexus? I haven't collected even a partial of this species yet, so confirmation would be exciting. Thanks for your thoughts, Jackson

This other one is probably complete. If it takes me prepping this one to get a 100% confirmation, please let me know and I will do so. (Would rather keep it to prep later)

Having dabbled in the crinoids of the Burlington, my LIMITED knowledge would lead me to your conclusion. There is a Burlington crinoid expert at BYU???? I had him ID one once. If no one knows his name, I will look for my notes on him.

Thanks! I'll try and get ahold of him when I get time, maybe this weekend!
