Geography
Country:Australia State/province:Victoria
Coordinates: 38.4° South, 144.1° East (view map)
Paleocoordinates:57.7° South, 142.4° East
Basis of coordinate:based on nearby landmark
Time
Period:Paleogene Epoch:Eocene
Stage:Priabonian 10 m.y. bin:Cenozoic 3
Key time interval:Late/Upper Eocene Pollen zone: middle Nothofagidites asperus
Age range of interval:37.71000 - 33.90000 m.y. ago
Stratigraphy
Formation:Demons Bluff
Stratigraphy comments: The fossiliferous clay lenses, then, which occur in sands that overlie the coal at the Anglesea open cut, are probably part of the base of the Demons Bluff Formation. The palynoflora of these lenses represents the middle Nothofagidites asperus zone, indicating a Late Eocene age and that a hiatus may be present at the top of the coal (A. D. Partridge, personal communication).
Lithology and environment
Primary lithology:lenticular carbonaceous claystone
Secondary lithology:"cross stratification",fine,coarse sandstone
Includes fossils?Y
Lithology description: The sequence includes course to fine cross-bedded sands with lens of carbonaceous clay (Chirstopher y Basinger , 1982). The fossiliferous clays form lenses within a thick deposit of fine to coarse, cross-bedded sands. The fossil flowers occur in a clay lens 5 m above the top of the coal seam (Basinger & Christophel, 1985).
Environment:"channel"
Geology comments: The clay lenses probably represent oxbow lakes or similar confined depressions within the valley of an extensive Eocene river system.
Taphonomy
Modes of preservation:adpression
Size of fossils:macrofossils,mesofossils,microfossils
Collection methods and comments
Collection excludes:some microfossils
Collection methods:chemical
Reason for describing collection:paleoecologic analysis
Collection method comments: Aproximately 100 flowers 80 complete leaves of Austrodiospyros have been recovered (Christophel & Basinger, 1982; Basinger & Christophel, 1985). 8 meter below of sequences described by Hill, 1978; 1980.
Taxonomic list comments:300 specimens.
