Help ID'ing Mississippian crinoid from KY


Recommended Posts

Hello!  I found this crinoid in Hardin County, KY earlier this morning that I would love to be able to ID further beyond "crinoid" haha.  I found it as is (no prepwork or cleaning) in a scree pile of misc Mississippian rocks and so not sure if specifically from Salem limestone, Harrodsburg limestone, Borden formation, St Louis limestone, etc.  I've included pics of the front and back of the rock/crinoid.  If it helps with ID'ing, the darker portions of the rock seem to be that tar-type limestone (and not surface dirt or soil, etc).  In reading the published literature on KY crinoids there seems to be quite a few genera identified from this era and this part of KY and so I would also like to learn from you on how one might narrow down a crinoid's genus.  Would also be iinterested in hearing your opinions on if it would help having it prepped out a bit by someone.  Thanks in advance for any assistance you could provide!

Wow! Great find! If you found that this morning you just beat the rain here. ;) 

 

I have to say I’m a bit :envy: 
 

I think we would need to know the formation to pin down an accurate genus/species, but maybe one of the others mentioned will recognize it. Looks a bit like Salem Limestone material to me.

Thanks everyone for your posts, literature, and encouragement!  I think first step then for me is to try and determine from what formation this specimen had fallen down from and then go from there.

While this would obviously be helpful, I think someone who really knows the crinoids from the area well (@crinus, @crinoid1) may well be able to suggest an ID.
