Pk1, Pondaung Sandstone (Eocene of Myanmar)

Also known as Sabapontaung (Sabapondaung) kyitchang

Where: Myanmar (21.8° N, 94.6° E: paleocoordinates 13.0° N, 93.1° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Pondaung Formation, Bartonian (41.3 - 38.0 Ma)

• this bed is approx 45 m above the base of the section at this locality

•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).

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; brown, yellow sandstone and brown, red mudstone

• fossils come from a dark red-brown mudstone

Size class: macrofossils

Collection methods: specimens held at National Museum of Myanmar
