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.
The dark bump in the above photo is currently thought to be a juvenile specimen of Primaspis crosotus!
