Lea River (Oligocene of Australia)

Where: Tasmania, Australia (41.5° S, 145.7° E: paleocoordinates 58.3° S, 145.0° E)

• coordinate stated in text

When: Proteacidites tuberculatus pollen zone, Early/Lower Oligocene (33.9 - 28.4 Ma)

• Early Oligocene sediments on the Lea River, north-western Tasmania (Jordan et al. 1998).

•The sediment has been dated by palynological correlation as Oligocene (M.K. Macphail pers. comm.).

Environment/lithology: terrestrial; siltstone

• The fossil bearing sediments are exposed in the relatively rapidly

•eroding bank of the Lea River.

•Conifer fossils from Hill et al. 2003 and Hill et al. 2008 were found in siltstone in the lower portion of the exposure and in loose blocks near the water line.
