Ordovician Cryptolithus Trilobite Fragments

These pictures show fragments of the Ordovician Period Cryptolithus trilobite found in Carroll County, Kentucky. It was found in the Kope Formation.


The U shaped collar is visible at both ends but the middle is obscured. I want air abrasive clean this fossil to try and reveal the entire cephalon (if intact). Mystery object in the left top corner could be a starfish arm.


You will need to click to enlarge this picture. This is a rock plate that had one of the previous shown trilobite fragments. Herb from KYANA Geological Society (Louisville, Kentucky) was looking at this piece and pointed out that this could be a starfish arm.

Ordovician Brachiopod Dalmanella

These Ordovician fossils are interesting in that some of them are reddish-maroon in color and others are gray. The brachiopods shown appear to be genus Dalmanella. They were found in Carroll County, Kentucky in the Kope Formation.

The shells are about 1 cm long.

Ordovician Flexicalymene Pygidiums

Yesterday, KYANA Geological Society stopped by Carroll County, Kentucky for some Ordovician siteseeing after a marvelous tour of the Cincinnati Museum Grier Collections Center fossil department. I took a lot of pictures of specimens to post! Here is a sample of Flexicalymene trilobite pygidium pieces I found on the roadcut. I think we were in the Kope Formation of the Ordovician Period.

This first piece is of an enrolled Flexicalymene with a damaged cephalon and pygidium.
