Patala Formation (Paleocene of Pakistan)

Where: Pakistan (32.7° N, 71.8° E: paleocoordinates 1.2° N, 64.8° E)

• coordinate stated in text

• local area-level geographic resolution

When: Patala Formation, Late/Upper Paleocene (58.7 - 55.8 Ma)

• STRATIGRAPHIC RELATIONS: From the Patala Limestone, which conformably overlies the Lockhart Limestone (Late Paleocene) and is gradationally overlain by the Nammal Formation (Early Eocene). THICKNESS: 91 m at type section, ranging from 26 to 126 m throughout its range. AGE: Late Paleocene in text. STRATIGRAPHIC POSITION: Collection is presumably a composite from the entire formation.

• formation-level stratigraphic resolution

Environment/lithology: shallow subtidal; shale and marl

• ENVIRONMENT: not reported in text, but from carbonate facies and appears to be rather shallow water on the basis of faunal composition.
• SPECIFIC LITHOLOGY: Shale and marl interbedded with minor limestone and sandstone. LITHIFICATION: Lithified, assumed on the basis of facies description.

Size class: macrofossils

Collection methods: COLLECTORS: Not stated, but probably Eames (1950's). REPOSITORY: Not stated, but probably BMNH.
