Vinton Canyon (Carboniferous to of the United States)

Where: El Paso County, Texas (32.0° N, 106.6° W: paleocoordinates 4.4° S, 41.0° W)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Bishop Cap Formation, Kashirian to Kashirian (313.8 - 307.0 Ma)

• Age as determined by authors: middle Desmoinesian

• formation-level stratigraphic resolution

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

• The gastropods described herein were collected from the lower 35m of the shale interval marking the lower part of the Bishop Cap Fm. The individual shale beds within this interval range from black, fissile, sparsely fossiliferous units to gray to light brown, thin-bedded shales and calcareous shales that containa prolific molluscan fauna. Numerous thin limestone beds, and several sandy to conglomeratic units are also present within the interval. Specimns were collected from the surface of the shale exposures, and bulk sediment samples were also taken for later wet-sieving and concentration of tiny gastropods.

Size class: macrofossils

Reposited in the NMMNH, UNM

Collection methods: bulk, surface (in situ), sieve,

• The number of specimens is based on non-uniform sampling methods, therfore the ecological utility of these abundances is unclear.
