Hangu Shales - Samana Range, Pakistan (Paleocene to of Pakistan)

Where: North-West Frontier, Pakistan (33.5° N, 71.1° E: paleocoordinates 0.1° N, 64.0° E)

• local area-level geographic resolution

When: Hangu Shale Member (Hangu Formation), Selandian to Selandian (61.7 - 55.8 Ma)

• The Hangu Shales are separated from underlying Albian rocks by about 500 ft of barren lithographic limestones and sandstones, the upper 140 ft of which constitute the Hangu Sandstones, which is conformable with the Hangu Shale, but unconformable with the Albian rocks. The shales are overlain conformably by 200 ft of limestone (the Lockhart Limestone). Refined age data obtained from Warwick et al. (2003) and references therein, which suggest a middle to late Paleocene age based on Pollen.

• formation-level stratigraphic resolution

Environment/lithology: marginal marine; lithified shale

• No specific environmental data presented in Cox (1932), but depositional environments in Warwick et al. (2003) suggest a marginal marine to shallow subtidal environment for the upper part of the Hangu Formation (terrestrial for the lower part).
• Shale. No more specific description than this

Size class: macrofossils

Collection methods: Collection made by Lt-Col. L.M. Davies during military service. Collection is derived from many sections along the continuous outcrop of Hangu Shale.
