Where: Tasmania, Australia (41.0° S, 147.9° E: paleocoordinates 61.2° S, 150.5° E)

• coordinate stated in text

When: Lower Nothofagidites asperus pollen zone, Middle Eocene to Middle Eocene (47.8 - 33.9 Ma)

• The Hasties mudstone was more difficult to date precisely but probably belongs in the Lower Nothofagidites asperus zone. The presence of Nothofagidites falcatus and N. asperus sets the maximum age, while Aglaoreidia qualumis sets both maximum and minimum ages. The remaining taxa have wide stratigraphic ranges, but none fall outside the suggested Middle-Late Eocene age (Stover and Partridge 1973).
