Of course, there isn’t merely a sedimentary / biological story recorded here; structural geology plays an important role in our interpretation, too. These turbidites (rocks deposited by turbidity currents) were involved in Appalachian mountain-building. When ancestral Africa collided with ancestral North America in the orogeny that assembled Pangaea, these strata were squeezed. Pressure solution on a microscopic level imparted a cleavage that’s most pronounced in the shalier layers:

A report from the field: new outcrops of Ordovician-aged turbidites featuring geopetal indicators, fossil content, and a structural overprint imparted during Pangaea's assembly.
