Eroded Crinoid Stem

Here is a crinoid stem piece from the Mississippian period. It was found at Lake Cumberland, Kentucky.

Cryptolithus Trilobite

Here a Cryptolithus trilobite from the Orodovician time period (438-505 million years ago). It was found in Carroll County, Kentucky. It is part of the head plate (cephalon) with a spine attached.

Conularia

Here is an odd creature that no one quite knows what it really looked like. It left a skeleton that is in the shape of a four sided pyramid with a lot of grooved lines on it. Some think it might be some sort of jellyfish but they have been found with stems.

Maybe some type of crinoid. It is called a Conularia and existed in the Mississippian time period. I believe this one was found in southern Louisville.
