Cable Canyon section B. 28.0 m (Ordovician of the United States)

Where: New Mexico (32.9° N, 107.2° W: paleocoordinates 12.6° S, 90.2° W)

• coordinate based on political unit

• outcrop-level geographic resolution

When: Symphysurina brevispicata trilobite zone, Bliss Sandstone Formation, Gasconadian (485.4 - 477.7 Ma)

• bed-level stratigraphic resolution

Environment/lithology: sandstone and limestone

• The Blissis dominated by poorly fossiliferous sandstone and dolomite across most of its area of exposure (Hayes, 1975), but the unit includes numerous thin beds and lenses of fossiliferous limestone in the Caballo Mountains.

Size classes: macrofossils, mesofossils
