Rugosa of the Sly Gap Formation, San Andreas Mts, southern New Mexico (Devonian of the United States)

Where: New Mexico (33.0° N, 107.0° W: paleocoordinates 29.8° S, 54.7° W)

• coordinate estimated from map

• local area-level geographic resolution

When: Sly Gap Formation, Frasnian (382.7 - 372.2 Ma)

• "approximately mid to late Frasnian" Assemblage "is clearly correlative with that of the Cerro Gordo member of the Lime Creek Fmn of Iowa."

• formation-level stratigraphic resolution

Environment/lithology: marine; calcareous shale and limestone

• "calcareous shales and limestones which vary considerably in thickness because of unconformities within and above the sequence" [Macgeea thomasi and Tabulophyllum ovinum occur throughout the formation; the remaining species are from a limestone in the upper part of the formation.]
