The assemblage can be referred to the middle Eocene Proteacidites confragosus. Zonule on the basis of the presence of the nominate species, and is the most inland of any Australian Tertiary flora described. The Napperby sediments may be correlated, on a palynological basis, with the upper part of the Eyre Formation of northeastern South Australia; they are older than the vertebrate-bearing Waite Formation of the adjoining Alcoota Sheet area. A high frequency of pollen from aquatic and marsh-loving angiosperms and the presence of dinoflagellate cysts indicates deposition under lacustrine conditions. The presence of Nothofagus and podocarpaceous pollen types in significant amounts suggests that a humid climate prevailed, although seasonal aridity cannot be ruled out. {"type": "Polygon", "coordinates": [[[132.0, -23.2], [135.0, -23.2], [135.0, -22.0], [132.0, -22.0], [132.0, -23.2]]]} 132.0 135.0 -23.2 -22.0 Earth Sciences GA Publication Journal NT Published_External Journal article (pdf) documentDigital Journal article (pdf) PDF Unnamed resource documentDigital HTML
