Also known as Albritton locality 8

Where: Comanche County, Texas (31.9° N, 98.6° W: paleocoordinates 29.8° N, 55.5° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Glen Rose Formation (Trinity Group), Aptian to Aptian (125.5 - 99.7 Ma)

• level 22

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; burrowed, bioturbated, shelly/skeletal, yellow, argillaceous, silty limestone

• "impure buff limestone, with mud-cracks, small tubular borings, and dinosaur tracks"; also described as "a buff, flaggy limestone...laminated...about 70% by weight of calcium carboante. The insoluble residue included particles of clay, silt, and fine sand, with the clay and silt fractions predominating. Larger clastic particles were of angular quartz...Much of the calcium carbonate in this layer is in the shells of ostracods and Foraminifera."

Size classes: macrofossils, microfossils

Preservation: mold/impression, trace, original calcite
