Penn Dixie Calyx

[Malcolmt]

It is very rare that a crinoid calyx is found a Penn Dixie. I was at Penn Yesterday in the blistering heat 39 Celsius and found a small calyx (23mm * 11 mm). I have a suspicion what this is but don't want to taint others before hearing their opinion. This was found in the top of the E. rana trilobite layer in the Windom shale. I prepped it this morning and the preservation is much better than the 1 other calyx that I have ever found there which I gave to DevonianDigger earlier this year. Here are a series of pictures that try to give the different views. There is the remains of one arm but it is disarticulated from the actual calyx.

I'm not versed enough to hazard a guess, but that sure is a great find!

Roger other than the rarity of it , nothing spectacular about it. But it does tick off another box for me for different species found at Penn Dixie. Now if only I could find that Dipleura
