Where: Kaufman County, Texas (32.6° N, 96.3° W: paleocoordinates 37.9° N, 73.9° W)

• coordinate based on political unit

• outcrop-level geographic resolution

When: Nacatoch Sand Formation, Maastrichtian (72.1 - 66.0 Ma)

• group of beds-level stratigraphic resolution

Environment/lithology: marine; concretionary, glauconitic, calcareous sandstone

• about 50 feet of greenish-gray massive slightly glauconitic sand with concretionary masses of calcareous sandstone containing fossils; concretions in a layer about 15 feet above the base are very fossiliferous, and are estimated to be near the middle of the formation;

Size class: mesofossils
