Crinoid Calyx Fragment

Here is the bottom of a crinoid calyx or head.

It is from Joe Prather Highway which is a location about an hour south of Louisville, Kentucky on I-65.

I am not sure of the species or time period. Will continue to research and post later.

Crinoid Cluster

Here is a cluster of crinoid stems from Kentucky Highway 313 or Joe Prather Highway from I-65 to Fort Knox. I am not sure what species it is or the time period for these fossils.

This site is less than an hours drive from Louisville south on I-65.

Platystrophia ponderosa Brachiopod

Here are a number of brachiopods found at the Bardstown Road site near Mt. Washington.
It appears most are Platystrophia ponderosa brachiopods.

Maybe 3 or so (near bottom left corner of image) could be Platystrophia cypha with its high arching like fins in the shell.

Two brachiopods on the far left column and in its middle are probably Hebertella brachiopods with the fine lines on the shell. The Ohio Fossils book (Bulletin 54 from Ohio Geological Survey, 1955) lists 3 species for Hebertella: Hebertella sinuata, Hebertella occidentalis, and Hebertella insculpta.
