The Cleveland Museum of Natural History is celebrating the 50th anniversary of the start of excavating fossil fishes from their area. In 1965 construction to create I-71 road connecting downtown Cleveland with its southwestern suburbs revealed a treasure trove of Devonian fossils.
The animals fossilized after their remains sank to the ocean bottom and settled in to the sediment that would turn into the Cleveland Shale. The team worked on extracting fossils and shale from the project till 1968. Animals like the Cladoelache shark and Dunkelosteous arthrodire where found there.
