Mississipian Crinoid ID


Nimravis

Recommended Posts

I am looking to see if someone can ID this Mississippian Crinoid calyx that I acquired about 30 years ago. It was found in Anna, Illinois at a location that I have been told is no longer available. Any help would be appreciated.

 

Thanks

Thanks John,

 

Although it has been sitting in a box for years and I am not a crinoid collector, it is cool looking and very thin.

Nice crinoid crowns (calyces, arms, pinnules).
Could you please post a picture of the first specimen from the base of the calyx, the attachment point to the columnal ?

This is a Phanocrinus formosus. Very common at Anna, but not with such a lovely anal tube as shown in the first picture.
