Stratigraphy
Stratigraphy comments: 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.).
Lithology and environment
Primary lithology: siltstone
Lithology description: 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.
Environment:terrestrial indet.
Taphonomy
Modes of preservation:adpression
Size of fossils:macrofossils
Collection methods and comments
Collection methods:chemical,peroxide
Reason for describing collection:taxonomic analysis
