Where: Iran (34.1° N, 58.1° E: paleocoordinates 15.9° S, 45.6° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Nayband Formation, Norian to Norian (228.0 - 201.3 Ma)

• Based on the abundant occurrence of Heterastridium conglobatum and H. lobatum, the index fossils of the Late Triassic (Norian-Rhaetian?), the section has been dated as Norian in age (Bidestan Member). However, based on the stratighraphic position (continuous transition to the Jurassic Ab-e Haji Formation) and lithology (carbonates and sandstones), this section corresponds to the Howz-e Khan Member, which is known from its type locality on the southern flank of the Kuh-e Nayband (geol. map J8 of Naybandan: Kluyver et al. 1983). This discrepancy perhaps reflects a different depositional environment of the Hassan-Abad section, which belonged to the Lute Block during the Late Triassic. As a result, Aghanabati (2004, 2010) suggested to use the informal name "Ferdows Member" for this part of the Nayband Formation.
