This is a very nice crinoid. It is a fine Macrocrinus mundulus from the famous Mississippian layers near Crawfordsville, Indiana. This type of Camerate crinoid has a large cup composed of many plates and biserial arms that contain many pinnules. This specimen is very inflated and exhibits fine detail. The plate structure of the cup is quite evident, and the arms are almost totally intact. A long, articulated stem is still tightly attached to the cup of the crinoid, and the anal tube can be seen extending above the tips of the arms. The sea lily has very good color and contrast and is beautifully centered on the semi-rectangular plate of siltstone. This is a very nice example of a classic crinoid from a renowned site.
