  • Steropodon galmani

    Steropodon galmani, a platypus-like monotreme from the Early Cretaceous of Australia, was the first Mesozoic mammal discovered from Australia. It is known from an opalised lower jaw with molar teeth found at the mining town of Lightning Ridge in north central New South Wales. The teeth of Steropodon are similar to those of later fossil platypuses although its molars are more archaic in form. Steropodon lived alongside dinosaurs, crocodiles, early birds and other early mammals on the forested shores of the inland Cretaceous Eromanga Sea.

  • Platypus, Ornithorhynchus anatinus

    The Platypus is a unique Australian species. Along with echidnas, Platypuses are grouped in a separate order of mammals known as monotremes, which are distinguished from all other mammals because they lay eggs. When first discovered, the unusual look of a Platypus caused considerable confusion and doubt amongst European naturalists and scientists, many of whom believed that the animal was a fake.

  • Chunia illuminata

    Chunia was a primitive ektopodontid, a distinctive group of Cainozoic Australian possums that may have been specialized seed-eaters. Ektopodontids, first thought to be monotremes, had short faces, large, forward-facing eyes and the most unusual and complex teeth of any marsupial. Chunia, the most primitive of the ektopodontids, had molar teeth that were simpler than those of other ektopodontids and much like those of phalangeroid possums.
