Where: Tasmania, Australia (42.2° S, 145.3° E)
• Paleocoordinates: 42.7° S, 145.5° E (Wright 2013)
• coordinate stated in text
When: Early/Lower Pleistocene to Early/Lower Pleistocene (2.6 - 0.1 Ma)
• The Regatta Point fossils are contained within transported blocks of sediment which have been dated by palynological correlation as Early or possibly Middle Pleistocene (Macphail et al. 1993). Dated as Late Pliocene-Early Pleistocene by Hill and Macphail, 1985; Wells & Hill, 1989.
Environment/lithology: lacustrine; gray mudstone and poorly lithified, fine-grained sandstone
•
•The fine-grained nature of the sediment matrix indicates distal deposition in a low-energy environment such as a lake, river estuary or a shallow inland harbour such as the one existing there today (Wells & Hill, 1989).
•The mudstone blocks are composed of quartz grains, black organic fragments,
•whole plant structures and cream-coloured mud flakes all dispersed through a dark brown-grey mudstone matrix (Wells & Hill, 1989). Macrofossils from Jordan, 1997 were extracted from mudstone, siltstone and sandstone clasts within the gravels.
Size classes: macrofossils, microfossils
Preservation: adpression, original sporopollenin
Collection methods: bulk, chemical, hydroflouric, sieve
• Repository: Department of Plant Science at the University of Tasmania.
•pollen count min. 400 identifiable pollen and spores (Jordan et al., 1995).
