3. Bishops whitmorei

Tiny mammal among Victoria’s dinosaurs

When the polar dinosaurs roamed Victoria 130 million years ago, this tiny mammal also thrived in the cool Gondwanan forests. Its teeth and jaws are only a few millimetres long. They were found fossilised in ancient riverbeds, along the modern coastline. It took keen eyes to spot them, and painstaking skill to free them from the rock. In life, it was likely an insect-eater, and looked much like today’s shrews or antechinuses.

Similarly aged mammals in Australia include the ancestors of the platypus and echidna. But exactly where Bishops sits in the mammal family tree is controversial: it might be related to the platypus and echidna or could be a vanished branch of placental mammals — the group that now includes cats, dogs and human beings.
