. "Silvabestius is an extinct genus of marsupial dating to the Early Miocene. They were grazing animals about the size of a modern sheep.This animal is known from two skulls found close together which have come to be known as the \"Madonna and Child\" fossils.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."@en . . . . . . . "Silvabestius"@en .
