About Silvabestius
Silvabestius is an extinct genus of diprotodontid marsupial which inhabited Australia during the Late Oligocene. Its fossils have been found from various sites at the Riversleigh World Heritage Area (north-western Queensland). Two species are currently known, S. johnnilandi and S. michaelbirti. A pair of well preserved Silvabestius skulls were found close together, believed to be from a mother and cub.
