Permian Period, 299-252 million years BP. A Glossopteris browniana fossil leaf assemblage from the Illawarra Coal Measures, Dunedoo, New South Wales, Australia. 1101 grams, 23cm (9"). From an old Bristol paleontological collection, acquired 1950s-1960s. Glossopteris leaves are a widespread fossil, but are difficult to assign by species because of the wide variety of venation patterns and morphology. They are found throughout what was once Gondwana, another support for continental drift. The genus derives its name from the Greek words for 'tongue' and 'fern'. They favoured a swampy habitat, and some had leaves up to a meter in length. [No Reserve]
