Pk2, Pondaung Sandstone (Eocene of Myanmar)

Where: Myanmar (21.8° N, 94.7° E: paleocoordinates 13.0° N, 93.1° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: upper Member (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 siliciclastic

Size class: macrofossils
