Quinkana is an extinct genus of crocodiles that lived in Australia from ~24 million years ago to ~40, 000 years ago. By the Pleistocene Quinkana had become one of the top terrestrial predators of Australia, possessing long legs and ziphodont teeth.

Zygomaturus is an extinct giant marsupial from Australia. It had a heavy body and thick legs and is believed to be similar to the modern Pygmy Hippopotamus in both size and build. The genus moved on all fours. It lived in the wet coastal margins of Australia and became extinct about 45, 000 years ago. It was a large sized animal, weighing 500 kg or more and standing about 1. 5 m tall and 2. 5 m long.

Dromornithidae (the dromornithids) were a clade of large, flightless Australian birds of the Oligocene through Pleistocene epochs. All are now extinct. They were long classified in Struthioniformes, but are now usually classified as Anseriformes. Dromornithids were part of the Australian megafauna. One species, Dromornis stirtoni, was 3 m tall. The collective term Australian megafauna is used to describe a number of comparatively large species of animals that lived in Australia until 50, 000 to 20, 000 years ago.

D. stirtoni restoration Dromornis stirtoni was three metres tall and weighed half a ton (500 kilos). This genus had a long neck and stub-like wings, rendering it flightless. Its legs were powerful, but it is not believed to have been a fast runner. The bird's beak was large and immensely powerful, leading early researchers to believe that it was used to shear through tough plant stalks.

Megafauna cave painting could be 40, 000 years old In May 2010, archaeologists announced the rediscovery of an Aboriginal rock art painting, possibly 40, 000 years old, at the Nawarla Gabarnmung rock art site in the Northern Territory, that depicts two of the birds in detail. Late survival of Genyornis in temperate south west Victoria has also recently been suggested, based on dateable Aboriginal traditions.

Palorchestes ('ancient leaper or dancer') is an extinct genus of terrestrial herbivorous marsupial. The genus was endemic to Australia, living from the Late Miocene subepoch through the Pleistocene epoch (around 11. 6 million years ago-11, 000 years ago), and thought to be in existence for approximately 11. 59 million years.

Phascolonus was a genus of prehistoric Australian marsupial in the wombat family. The largest species, Phascolonus gigas weighed as much as 200 kg. Phascolonus existed alongside with an even larger marsupial, Diprotodon, which weighed as much as three tons and was distantly related to wombats.

Protemnodon is a genus of megafaunal macropods that existed in Australia, Tasmania and Papua New Guinea in the Pleistocene. Based on fossil evidence it is thought that Protemnodon was physically similar to wallabies but far larger; Protemnodon hopei was the smallest in the genus weighing about 45 kilograms, the other species all weighed over 110 kg.

Sthenurus ("Strong Tail") is an extinct genus of kangaroo. With a length of about 3 m, some species were twice as large as modern extant species.

The giant koala (Phascolarctos stirtoni) was an arboreal marsupial which existed in Australia during the Pleistocene epoch. Phascolarctos stirtoni was about one third larger than the contemporary koala and has had an estimated weight 13 kg , which is the same weight as a large contemporary male koala. The two koala species co-existed during the Pleistocene, occupying the same arboreal niche.

Meiolania ("small roamer") is an extinct genus of cryptodire turtle from the Oligocene to Holocene, with the last relict populations at New Caledonia which survived until 2, 000 years ago. Meiolania had an unusually shaped skull that sported many knob-like and horn-like protrusions. Two large horns faced sideways, giving the skull a total width of 60 centimetres, and would have prevented the animal fully withdrawing its head into its shell. The tail was protected by armored 'rings', and sported thorn-like spikes at the end. The animal was rather large, measuring 2. 5 metres in length. Horned turtle Meiolania platyceps (extinct). Fossil specimen in Lord Howe Island museum.

Simosthenurus is a genus of megafaunal macropods that existed in Australia in the Pleistocene. The members of the genus are large, Simosthenurus occidentalis weighed over 118 kilograms. Simosthenurus occidentalis

Mammoth Cave is the earliest Palaeontological cave site to be found within W. A. Reports of the discovery of Mammoth Cave date back to as early as 1895. Mammoth Cave was located by Surveyor Mr Marmaduke Terry in September 1900, and explored by Tim Connelly and Ned Dawson, with Ned being the first to go through the cave and discover the “back door”. Tim conducted unofficial tours through the cave until 1904 when it was officially opened as a tourist cave. He also named the cave “The Dawn of Creation” perhaps due to the expanse of light reflecting off the stream in winter or maybe because of the abundance of fossils found in the cave.

The Alcoota Fossil Beds, located on Alcoota Station in Central Australia, provide evidence of the evolution of the Northern Territory’s fauna and climate. The Fossil Beds are a unique occurrence of well-preserved, often rare, Tertiary vertebrate fossils, the study of which will furnish a better understanding of the modern Australian fauna. Fig. 1.

New Zealand geese The New Zealand geese formed the extinct genus Cnemiornis. The genus, endemic to New Zealand, consisted of two species: the North Island Goose, C. gracilis and the South Island Goose C. calcitrans. They were flightless with much-reduced webbing on the feet, an adaptation for terrestrial dwelling similar to that of the nene of Hawaii. They were never particularly common, and like many other large New Zealand endemic species they were subject to hunting pressures from the settling Polynesians, as well as predation upon their eggs and hatchlings by kiore (which accompanied the settlers) and the settlers' dogs, and were extinct before the arrival of European settlers.
