Also known as Dinner Springs Canyon
Where: Elko County, Nevada (41.5° N, 114.2° W: paleocoordinates 12.1° N, 37.5° W)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Meekoceras gracilitatis ammonoid zone, Thaynes Formation, Smithian (251.3 - 247.2 Ma)
• STRATIGRAPHIC RELATIONS: Unknown bounding lithostratigraphic units. Within the Thaynes limestone this unit overlies the 18 ft thick limestone of unit c, and underlies another 48 ft thick limestone of unit e. THICKNESS: Stratigraphic section of 175 ft. AGE: Meekoceras graciliatus zone, Scythian stage. Assigned here to the Olenekian by the enterer. STRATIGRAPHIC POSITION: Collection is from "Unit d", a 15 ft thick limestone. LITHOSTRATIGRAPHY: No lithostratigraphic units named in Kummel and Steele (1962). Assignment to the Thaynes Fm is based on more recent publications from the same sections, including Gardner and Mapes (2000).

Environment/lithology: deep subtidal shelf; lithified, fine-grained, medium, shelly/skeletal, gray limestone
Size class: macrofossils
Preservation: cast, mold/impression
Reposited in the MCZ
Collection methods: quarrying,
• COLLECTOR: G. Steele (late 1950's). REPOSITORY: MCZ.
