Where: Tasmania, Australia (41.2° S, 145.2° E: paleocoordinates 55.6° S, 144.0° E)
• coordinate stated in text
When: Proteacidites tuberculatus pollen zone, Late/Upper Oligocene (28.4 - 23.0 Ma)
• The fossil-bearing mudstone has been dated by palynological correlation by M. K. Macphail. He considers that the mudstone belongs to the lower Proteacidites tuberculatus Zone of Stover & Partridge, 1973 (hill & Bigwood, 1987). Macphail (in Hill 1987) suggested a Late Oligocene age for the flora.
•The sediments are dated palynologically as Early Oligocene (Macphail et al. 1994) in Guerin & Hill, 2003.
Environment/lithology: lacustrine; poorly lithified, gray mudstone and coarse-grained, gray sandstone
•Above the organic layer which separates the two units the sediment changes suddenly to a coarser grained material composed of dark grey sands, once again rich in black organic material. Both upper and lower units are consolidated when dry but become plastic when wet. Fossils from Hill, 1989 & Hill and Carpenter, 1989 were recovered from the fluviatile sands of this place.
Size class: macrofossils
• Several vegetative fragments and one ovulate cone were retrieved.
Collection methods: chemical, peroxide, sieve
• Fossils collected by R. S. Hill from 1992 to 1998 (Guerin & Hill, 2003).
