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.

Foerstephyllum Colonial Coral

Unknown species of a Foerstephyllum sp. colonial coral found in eastern Jefferson County in the Liberty formation. This coral existed in the Ordovician time period.

Happy 200th birthday to Charles Darwin! Not sure if this coral showed up in any of his research though.
