Also known as Than-udaw AMNH A8
Where: Myanmar (21.7° N, 94.8° E: paleocoordinates 13.1° N, 93.3° E)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Pondaung Formation, Bartonian (41.3 - 38.0 Ma)
• The whole sequence of units was originally defined as the ‘Pondaung Sandstones’ by Cotter (1914), but the horizon yielding Eocene vertebrate fossils is now known as the ‘Upper Member’ of the Pondaung Formation (see Maung et al. 2005). The most recent age for this unit is ~39–38 Ma and so it can be regarded as middle Bartonian (see Tsubamoto et al. 2011).
• formation-level stratigraphic resolution
Environment/lithology: terrestrial; brown, yellow sandstone and red, white, yellow siliciclastic
Size class: macrofossils
Reposited in the AMNH
• collected by H. M. Lahiri, specimens housed in the Geological Museum, Calcutta and AMNH
•Colbert's list has both Pondaung and Upper Irrawaddy associated with the fossils he reports, but it's not clear what that means
