Pyrite Trepospira Gastropod Fossil

This gastropod fossil is interesting as it pyrite embedded in a dark shale. It appears to be a Trepospira. It was found in a coal mine at a depth of 60-250 meters.

My identification source is Fossils of Ohio (Bulletin 70, Rodney M. Feldmann Editor, State of Ohio, Department of Natural Resources, Division of Geological Survey, Columbus Ohio 1986) pages 162-173, figures 13-14 of specimen from Putnam Hill shale (Allegheny Group, Pennsylvanian) south of New Philadelphia, Tuscarawas County Ohio, OSU 46720.

The fossil was situated above the coal seam so it might be from the Pennsylvanian Period (late Carboniferous). It was found in Webster County Kentucky USA. The mines there are part of the Eastern Interior Basin. The formations found there are Sturgis, Carbondale, and Tradewater. The limestone layers are Carthage, Madisonville, Providence, Yeargiss?, and Lead Creek.

Coal Mine Cephalopod Fossil

This fossil is somewhat rare because it was found at a depth of 60-250 meters underground. The fossil was situated above the coal seam so it might be from the Pennsylvanian Period (late Carboniferous). It was found in Webster County Kentucky USA. The mines there are part of the Eastern Interior Basin. The formations found there are Sturgis, Carbondale, and Tradewater. The limestone layers are Carthage, Madisonville, Providence, Yeargiss?, and Lead Creek.

I would identify it as Pseudorthorceras. 

This next image shows two more fossils found at the same location. A cephalopod fossil that is about 17 cm long. It is next to a large crinoid stem segment.

Cnemidium Sponge Fossil

The image shown is of a Cnemidium pertuscum Reuss sponge fossil at the Museo di Paleontologia at Sapienza University of Rome Italy. Animals like this existed at the time of the Upper Cretaceous Period (Cenomanian). The fossil was found in Bilin, Bohemia, Czech Republic.
