The name Glossopteris translates as 'fern shape', these deciduous Glossopteris browniana leaf specimens help to form part of the most recent theories on tectonic plate movement and continental drift science, because these fossil leaf impressions can be found in limestone plates, which were presumably once the silts in and around lakes and lagoons in Antarctica, Australia, India, South America, Madagascar and Africa.

These southern hemisphere clues contributed to firm up and theorise the formation and break up of the super single continent Gondwanaland. This one landmass began to break up and drift apart approximately 150 million years ago.
