Trilobite: Primaspis crosotus

These excellent specimens of the trilobite Primaspis crosotus (suspected by some to be Meadowtownella crosotus) were found by John Tate on the underside of a coned bryozoan called Prasapora simulatrix. This fossil is from the Southgate member of the Latonia (Kope) Formation and is from a hill cut site in Northern Kentucky. Specimens of this trilobite are often found by turning over coned bryozoans found in the Southgate.
