Excavation at Big Creek, 1927
Fossil hunters from the Cleveland Museum of Natural History haul a concretion up the bank in Big Creek Reservation. Encased in the stone was the head and fore fins of a Cladoselache. The remains of this Devonian shark species were incredibly well-preserved within Cleveland shale; some specimens have even yielded visual traces of the Cladoselache's organs, muscles and skin.
