Silvabestius is an extinct genus of marsupial dating to the Early Miocene. They were grazing animals about the size of a modern sheep. This is proven as the skull size was about 25cm long. The Silvabestius is 1m long in length. The Silvabestius was a herbivore which browsed on soft plant matter such as leaves and stems. Silvabestius lived in an environment that largely consisted of tropical rainforests. The Silvabestius has close living relatives that exist now such as koalas and wombats which are found in Australia. The Silvabestius is in the extinct family called the Diprotodontidae and is therefore closely related to the giant marsupial Diprotodon. Two well preserved fossils were found belonging to a Silvabestius these fossils were 2 skulls believed to be a mother and child, These skulls were found in Riversleigh Queensland, Australia. The two skulls were found extremely close together. The baby believed to of been in the mothers pouch when they died. The fossil is referred to Madonna and child.
