Two Meristella maria Brachiopods

Imprint remains of fossilized brachiopods called Meristella maria [the genus Meristina can also be used].  These animals lived in the Middle Silurian Period.  Fossils found in the Waldron Shale of  Clark County, Indiana.

Pictures of second specimen.

Pyrite Coated Brachiopod + Crinoid

Picture of a Silurian Period brachiopod and crinoid stem coated in pyrite.  I am guessing this would be a concretion?  Fossils found in the Laurel Dolomite of Nelson County, Kentucky.

 Next picture shows the gray dolomite on the other side of the pyrite concretion.

Eospirifer With Partial Bryozoan Coating
