The Mississippian Borden Formation is a mapped bedrock unit in Kentucky, Indiana, Illinois, Ohio, West Virginia,[7] and Tennessee. It has many members, which has led some geologists to consider it a group (for example in Indiana[8]) rather than a formation (for example in Kentucky[1][4]).

Fossils

A rare soft-bodied fossil that was recovered from the Farmers Member of the Borden Formation in northeastern Kentucky was interpreted as a chondrophorine float (an internal anatomical feature).[13]

Trace Fossils

Zoophycos from turbidites of Farmers Member of Borden Formation at mile marker 135, I-64, Kentucky.

Zoophycos is present in the turbidites of the Farmers Member of the Borden Formation in Kentucky.
