USGS 00762 (Cretaceous of the United States)

Also known as Near Chatfield, from fossiliferous concretions in the village and in fields and ravines to the west, Navarro County.

Where: Navarro County, Texas (32.1° N, 96.5° W: paleocoordinates 36.9° N, 68.8° W)

• coordinate based on political unit

• outcrop-level geographic resolution

When: Nostoceras hyatti ammonoid zone, Nacatoch Sand Formation, Late/Upper Campanian (83.5 - 70.6 Ma)

• Stephenson (1941) had this unit as Maastrichtian, Cobban and Kennedy (1995) have updated it to uppermost Campanian via ammonite zonation.

• group of beds-level stratigraphic resolution

Environment/lithology: marine; concretionary lithology not reported

• fossiliferous concretions

Size class: mesofossils

Reposited in the USGS
