Lakhpat Fort (Eocene of India)

Where: Gujarat, India (23.8° N, 68.8° E: paleocoordinates 7.9° N, 62.3° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Upper Member (Fulra Limestone Formation), Middle Eocene (47.8 - 37.7 Ma)

• "from the uppermost 2.7 m... The Fulra Limestone here is approximately 12 m thick"

• member-level stratigraphic resolution

Environment/lithology: lagoonal or restricted shallow subtidal; lithified, argillaceous reef rocks and lithified, silty marl

• "a very shallow shelf, a quiet, sheltered, probably lagoonal environment"
• lithology in this part of the formation is "mainly moderately coarse rudstones and floatstones that may be argillaceous" but Verrucocoelia specimen is from "a silty, tan marl" (Rigby and Mohanti 1993)

Size class: macrofossils

Collected by M. Mohanti in 1989

Collection methods: peel or thin section,
