This animal is known from two skulls found close together which have come to be known as the "Madonna and Child" fossils.[1]
Silvabestius was 1 metre in length, with a skull about 25 cm long. It was a herbivore which browsed on soft plant matter such as leaves and stems and lived in an environment that largely consisted of tropical rainforest. Silvabestius is in the family Diprotodontidae and is therefore related to the extinct giant marsupial Diprotodon as well as to living koalas and wombats. Two well preserved Silvabestius skulls were found close together, believed to be from a mother and child, in Riversleigh, Queensland, Australia. The juvenile is believed to have been in the mother's pouch when they died.[citation needed]
