First fossil charophytes from Australia: a Sycidiale from the Frasnian (Late Devonian) Mytton Formation of northeastern Australia

WA Museum Records and Supplements | Updated 1 decade ago

Abstract - Sycidium reticulatum Sandberger from a probable early Frasnian horizon in the Mytton Formation of the Broken River area, northeastern Queensland, is the first fossil charophyte to be reported from Australia. Most of the gyrogonites of S. reticulatum are represented by internal moulds showing internal features such as the hitherto poorly known oospore and basal plate morphology. The presence of S. reticulatum in Queensland extends the distribution of charophytes along the North Gondwana margin, and is consistent with a low latitude climatic zone.
