AMNH locality 2015, Powwow Canyon (Carboniferous of the United States)

Also known as Unit V of section H, locality 32 of King and Knight (1945), sheet 2 (also see Knight and King (1946) fieldnote #1760, USGS Field Records Library, Denver).

Where: Texas (31.8° N, 106.0° W: paleocoordinates 5.9° S, 42.2° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Magdalena Limestone Formation, Morrowan (323.2 - 318.6 Ma)

• 11' thick bed

• group of beds-level stratigraphic resolution

Environment/lithology: offshore shelf; cherty/siliceous limestone

• This suggests an off-shore environment. However, Lane (1981: 200-201) cited evidence of several Pennsylvanian faunas such as those in the Perth Limestone of Indiana where spiculites are associated with coal cyclothems indicating

•shallower water. However, in much of the Paleozoic, spiculites are suggested to represent off-shore, deepwater niches.

• ... a gray limestone, 11 ft thick, containing numerous chert nodules. These nodules and the limestone commonly contain specimens of Millerella marblensis, Fusiella, various textulariid genera, a linguloid brachiopod, hexactinellid sponge spicules, and crinoid fragments in addition to the dominant gastropods.

•The matrix consists of well-sorted invertebrate fragments about the same size

•as the majority of the gastropods, along with scattered glass sponge spicules.

Size class: macrofossils

Reposited in the AMNH
