Where: Myanmar (21.7° N, 94.8° E: paleocoordinates 13.0° N, 93.2° E)
• coordinate estimated from map
• 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
