Taphonomy and depositional circumstances of exceptionally preserved fossils from the Kinzers Formation (Cambrian), southeastern Pennsylvania

Sedimentary and biological evidence suggests that anoxia, salinity fluctuations, and sedimentary obrution played relatively minor roles in the Emigsville Member of the Kinzers Formation. The abundance of exceptionally preserved remains suggests that exceptional sedimentary conditions were not necessary in the Cambrian in order for exceptional preservation to occur. The abundance of predation evidence in a deposit of exceptional preservation reinforces the concept that predation was the primary taphonomic filter during Cambrian time.
