Where: Pakistan (25.3° N, 67.9° E: paleocoordinates 7.8° N, 61.7° E)
• coordinate stated in text
• outcrop-level geographic resolution
When: Tiyon Formation, Lutetian (47.8 - 41.3 Ma)
• STRATIGRAPHIC RELATIONS: From the Tiyon Fm, which gradationally overlies the Laki Fm (Ypresian) and is gradationally overlain by the Kirthar Fm (Late Middle Eocene-Early Miocene). THICKNESS: 439 ft thick in total. AGE: Early Eocene-early Middle Eocene (Hunting Survey Corporation). Iqbal suggests that the age is not as old as Early Eocene, but is Middle Eocene. A Lutetian age is assigned by the enterer. STRATIGRAPHIC POSITION: From unknown position within formation.
• bed-level stratigraphic resolution
Environment/lithology: coastal; poorly lithified, gypsiferous, shelly/skeletal, gray, green, yellow, calcareous shale
Size class: macrofossils
Collected by Iqbal in 1966, 1972
Collection methods: surface (in situ),
• COLLECTOR: Iqbal (1966, 1972). REPOSITPRY: Geological Survey of Pakistan, Quetta.
