TMM 43024, Cross Branch (Cretaceous of the United States)

Where: Somervell County, Texas (32.2° N, 97.8° W: paleocoordinates 29.7° N, 57.7° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Upper Member (Glen Rose Formation), Albian (112.6 - 99.7 Ma)

• bed-level stratigraphic resolution

Environment/lithology: marine; dolomitic lime mudstone and wackestone

• Two formations because found in sandstone at base of Paluxy but time equivalent to the uppermost part of the Glen Rose. Also, contact between the two formations is gradational.
• dolomitic micrite/mudstone

Size class: macrofossils

Preservation: mold/impression, trace

Reposited in the TMM
