Ginkgo Leaves from Paleogene Sediments in Tasmania

Abstract

A single nearly complete leaf and several fragments in Paleogene sediments from southern Tasmania confirm the Cenozoic presence of Ginkgo L. in Australia. The specimens, assigned to G. australis McCoy, add to our knowledge of probable deciduous forms in the southern Australian Paleogene, when winter darkness at the prevailing high latitudes made this strategy competitive.
