FOSSILS FROM NORTHWESTERN PENNSYLVANIA

Intensive collection over the last 30 years has revealed a diverse number of Late Devonian and Pleistocene fossils including horseshoe crabs, placoderms, condrophores, echinoids, plants, phyllocarids, mammoth, mastodon and others in the northwest Pennsylvania region. Since many of these are new to the area or are not well known, we present faunal lists, photos and discussion relating to recovery of the specimens as well as suggestions for further exploration in the area.

The main sites where fossils have been recovered are road cuts, beaches, stream beds, construction excavations and other man-made exposures. The two time periods present are the result of a regional unconformity that has eliminated the intervening sediments.
