beds 39-40, Milepost 5 roadcut section (Carboniferous of the United States)

Where: Lincoln County, New Mexico (33.4° N, 105.9° W: paleocoordinates 1.9° S, 37.6° W)

• outcrop-level geographic resolution

When: Idiognathodus lobulatus conodont zone, Holder Formation, Virgilian (303.7 - 298.9 Ma)

• = Streptognathodus deflectus zone.

• bed-level stratigraphic resolution

Environment/lithology: gray, calcareous shale and gray, argillaceous, calcareous limestone

• The Holder Formation along Dry Canyon consists of a cyclic succession of Virgilian marine siliciclastics, marine carbonates, and nonmarine siliciclastics, including a large basal algal bioherm complex, deposited on a narrow shelf just west of the shoreline of the Pedernal land mass.
• Bed 39, an approximately 1-mt hick (3-ft-thick) dark-gray shale unit, and bed 40, a 1.15-m-thick (3.5-ft-thick) interval of thin ledge-forming light-gray to locally nodular limestone and dark-gray to brown-weathering calcareous shale/argillaceous limestone, are the sources of most, if not all, of the fossils in this second assemblage.

Size class: macrofossils

Reposited in the UNM
