Zeacrinites Crinoid Calyx

Here is a picture of one sweet find. It appears to be a Zeacrinites wortheni (Hall, 1858) crinoid calyx fossil. It was found in the Glen Dean Formation of Grayson County, Kentucky, USA. The fossil is about 2 cm tall and consists of the calyx cup, arms and even some of the pinnules. The creature dates to Chesterian, Upper Mississippian Period.

Curious about how Zeacrinites Troost, 1858 was named? Check out this post to learn more:
