Unit 4 Kinney Brick Company Quarry (Carboniferous of the United States)

Where: Bernalillo County County, New Mexico (34.9° N, 106.3° W: paleocoordinates 1.2° S, 37.7° W)

When: Wild Cow Formation (Madera Group), Kasimovian (307.0 - 303.7 Ma)

• other authors report Virgilian age for the strata; this author argues for middle to late Missourian age referring to brachiopods and conodonts which would then put the strata into the lower protion of the Pine Shadow or upper part of the Sol se Mete Members

Environment/lithology: lagoonal or restricted shallow subtidal; shale

• in general: strata define a regressive facies sequence which reflects the pro-gradation of a clastic delta; depositional history of this delta was interrupted on at least two occasions by marine transgressions

•unit 4: small-scale levees suggest that low-velocity currents occasonally scoured the substrate surface; desiccation cracks

• microlaminated, fissile shale; contains rare, centimeter-scale levees which truncate bundles of laminae; carbonate layers are less conspicous in the lower 5 cm of the unit and absent higher up

Size classes: macrofossils, mesofossils
