Loc. 506c. 3 miles due east of School for Blind at north edge of Alamogordo (Devonian of the United States)
Where: Otero County, New Mexico (32.9° N, 105.9° W: paleocoordinates 30.5° S, 54.1° W)
When: upper Palmatolepis gigas conodont zone, Upper Member (Sly Gap Formation), Frasnian (382.7 - 372.2 Ma)
• Upper part of Sly Gap is upper Palmatolepis gigas zone.
• member-level stratigraphic resolution
Environment/lithology: marine; gray shale
• The sequence is dominantly shaly and is composed of dark gray laminated shaly units alternating with greenish gray nodular units, not unlike Percha lithic types but lighter in color. The calcareous nodules are particularly dense in the lower, middle and uppermost parts of the formation. These fossiliferous nodular zones are, essentially, units D, G, and upper- most unit H of Stevenson (1945).
Size class: macrofossils
Reposited in the USNM
