The Kinzers Formation is a geologic formation in Pennsylvania. It preserves fossils dating back to the Cambrian Period.
The base of the Kinzers Formation is primarily a dark-brown shale. The middle is a gray and white spotted limestone and, locally, marble having irregular partings. The top is a sandy limestone which weathers to a fine-grained, friable, porous, sandy mass.[2]
Type section
Named from exposures at a railroad cut at Kinzers, Lancaster County, Pennsylvania.[1]
Other outcrops
High quality fossil specimens (Lagerstätte) were obtained from the Getz Quarry, near Rohrerstown, Pennsylvania, but the location no longer exists. The fossils are from the Emigsville Member, and include the trilobite Olenellus thompsoni, the arthropod Anomalocaris pennsylvanica, the bivalve Tuzoia getzi, and the green algae Margaretia dorus.
