Lexington Limestone Microfossils

These microfossils were found in the Lexington Limestone of Franklin County, Kentucky. They existed in the Ordovician Period. This first fossil is a snail or gastropod. It appears to be composed of some sort of black material.  All fossils are about 1 mm in length. A microscope was used to magnify 40x.

This fossil might be a crinoid stem fragment.
