Where: Queensland, Australia (19.0° S, 138.6° E: paleocoordinates 28.0° S, 135.8° E)

• coordinate estimated from map

When: Faunal Zone C zone, Middle Miocene (16.0 - 11.6 Ma)

• "early to middle Miocene... approximately 15 to 20 million years old" (Hand and Kirsch, 2003); Middle Miocene based on Woodhead et al. (2014)

• group of beds-level stratigraphic resolution
