Unit 8, Jerruck (Ranikot Series), India - Nuttall (1932) (Eocene of India)

Where: India (34.2° N, 74.8° E: paleocoordinates 7.2° N, 69.1° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Upper Ranikot Group, Early/Lower Eocene (55.8 - 48.6 Ma)

• Limestone unit (6 ft thick), 82 ft from base of 160 ft thick section, underlying shales, and overlying sandstone. This is the uppermost Upper Ranikot, and conformably overlies the Lower Ranikot Series, and is unconformably overlain by the Laki Series. The section corresponds to Vredenburg's Zone 4. Evidence for the lower Eocene age assignment is not presented, but the enterer suspects a microfaunal basis. Unit numbering is of the enterer's iniative and is numbered from bottom to top, each unit representing each of the author's lithological subdivisions.

• bed-level stratigraphic resolution

Environment/lithology: poorly lithified, concretionary, shelly/skeletal limestone

• Carbonate. No paleoenvironmental data reported.
• Limestone. Soft, crumbly, impure, nodular limestone very rich in fossils.

Size classes: macrofossils, microfossils

Collection methods: quarrying,

• Observations assumed to be undertaken by the author. No collections reported.
