Where: South Australia, Australia (30.5° S, 131.5° E: paleocoordinates 39.9° S, 127.9° E)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Nullarbor Formation, Langhian (16.0 - 13.8 Ma)
• Presence of Austrotrillina howchini and Flosculinella bontangensis in the Nullarbor Limestone suggest Middle Miocene age. "Late early Miocene to early middle Miocene" according to O'Connell et al. (2012). Watson Quarry section exposes the upper part of the Nullarbor (O'Connell et al., 2012), so an early middle Miocene age assigned here.
• group of beds-level stratigraphic resolution
Environment/lithology: open shallow subtidal; lithified limestone
Size class: macrofossils
Collection methods: Repository: South Australian Museum
