Where: Socorro County, New Mexico (34.1° N, 106.8° W: paleocoordinates 1.6° S, 38.5° W)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Tinajas Member (Atrasado Formation), Kasimovian (307.0 - 303.7 Ma)
• Stratigraphically high in the Tinajas Member of the Atrasado Formation. Conodonts from the Tinajas Member indicate that the upper part of the member, including the bed that produced the chondrichthyan fossil, is of late Missourian (late Kasimovian) age, close to the Missourian-Virgilian boundary.
• bed-level stratigraphic resolution
Environment/lithology: shoreface; lithified, coarse-grained, calcareous sandstone
Size class: macrofossils
Reposited in the NMMNH
