Also known as Kinney Quarry, basal limestone

Where: Bernalillo County County, New Mexico (34.8° N, 106.3° W: paleocoordinates 1.3° S, 37.8° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Pine Shadow Member (Wild Cow Formation), Kasimovian (307.0 - 303.7 Ma)

• The section of the quarry is part of the Pine Shadow Member of the Wild Cow Formation, Madera Group. The entire member has an average thickness of 70m in the Manzanita/Manzano Mountains, and has been reliably dated a s early to middle Virgilian on the basis of fusulinids described from localities elsewhere in these mountains. The dark limestone containing the marine fauna discussed here forms the floor of the quarry and is the basal unit (unit 1) of the stratigraphic section exposed in the quarry. Total thickness of this limestone unit is not known; it does not crop out significantly in areas immediately around the quarry. About 0.5 m is exposed in the quarry, and the upper 20 to 30 cm are widely present there.

•According to Lucas et al., 2011: The Kinney conodont fauna is characterized by Idiognathodus corrugatus and I. cherryvalensis, which suggest an assignment to the Idiognathodus confragus Zone of the North America Midcontinent region (Dennis cyclothem; middle Missourian).
