EQ- 10 (Cambrian of the United States)

Where: Pennsylvania (41.8° N, 78.7° W)

• Paleocoordinates: 10.6° N, 102.7° W (Wright 2013)

• coordinate estimated from map

When: Elvinia trilobite zone, Ore Hill Limestone Member (Gatesburg Formation), Steptoean (497.0 - 493.5 Ma)

Environment/lithology: marine; limestone

• Loch and Taylor do not describe lithology, however Wilson 1951 described this unit as massive dark crystalline dolomite, most of the Ore Hill limestone is typically thin-bedded and weathers into yellow mottled blue-gray flagstones 1-4 inches thick, finely crystalline or aphanetic and when fresh, quite black.

Size class: macrofossils

Preservation: cast

Collection methods: Trilobites collected from Eschelman Quarry section of the Ore Hill member of the Gatesburg formation Collection EQ-10 56ft from the base of the formation
