Ordovician, Decorah Formation Minnesota
Just want your opinions on it before I post it to my image gallery. I'm not a crinoid expert and this is rare - only my second crinoid from the Decorah Formation with more than 60% completeness. The first is a tiny one not even 2 inches from crown to base. This is more of a medium size with 110 mm from head to base. Using paint I pinpointed different areas for helpful info.
#1 Is the arms - can't really see in picture but very clear to me some scavenger buried the arms - I could see a few faint tunnels a short distance away.
#2 is most of the main stem - partial exposed.
#3 is scattered stem pieces, a couple belong to a different genus which I had not identify yet.
#4 is a fragment of arm?
#5 is the base.
