Australian Vertebrates:
During the Cretaceous, Gondwana (the super continent of the southern hemisphere, consisting of what is now Africa, India, Antarctica, South America and Australia) breaks into pieces. India moves to the north and South America to the west. The northern hemisphere contains two continents: Asiamerica, consisting of current Asia and the western part of North America, and Euramerica, consisting of Europe and the eastern part of North America. During the Eocene, Australia breaks away from Antarctica and moves northwards. During the Middle Pliocene, South America comes into contact with Central and North America, after which a lot of animals from South America move northwards, but also vice versa. Until the Pliocene, marsupials were common in South America, but in the second half of the Pliocene they are almost all replaced by placental mammals from North America. Marsupials can now only be found in great numbers in Australia.
The oldest marsupial fossils are found in deposits from the Early Cretaceous in Asia. From there they spread to North America and then to South America and Australasia. In the early Tertiary, North American marsupials spread to Eurasia, where they survived until the Miocene, and Africa, where they already became extinct earlier. In North America, they became extinct in the Miocene, but reinvaded from South America in the Pliocene.
Approximately 65 million years ago, South American marsupials entered Australia via Antarctica. Australian marsupials were able to develop strongly without the competition of placental mammals when Australia detached from Antarctica in the Eocene. Only bats were able to reach Australia in the Upper Oligocene, and rodents in the Upper Miocene, both via Indonesia. The most spectacular Australian marsupial faunas are known from the Pleistocene, when giant kangaroos, wombats and diprotodonts lived with marsupial “lions”, heavily armoured turtles and the giant varanoid lizard Megalania.

Kangaroos 

A kangaroo is a herbivorous marsupial from the family Macropodidae (macropods, meaning ‘large foot’). Besides the well-known larger species such as the red and grey kangaroo, the family also includes many smaller species which include the wallabies, tree kangaroos, wallaroos, pademelons and the quokka, more than 60 living species in all. The bigger species are endemic to Australia, while some smaller species can also be found in New Guinea. Like all marsupials, female kangaroos have a pouch in which the young (the ‘joeys’) complete postnatal development.
Kangaroos arose in the early Miocene, but, being grazers, they prospered in the Pliocene and Pleistocene, after Australia’s tropical rainforests were replaced by grasslands in the late Miocene. Dozens of extinct species are known, two genera (Ekaltadeta and Propleopus) were even carnivorous or at least omnivorous. 

Baringa nelsonensis
This is a very rare extinct species of wallaby known only from the Nelson Bay site in western Victoria. It lived in the early Pleistocene. ‘Baring’ is a Victorian Aboriginal word meaning ‘to cut’, an allusion to the unusual truncation by wear of the lower incisors. The species name reflects the type locality. Baringa was named on the basis of several fragmentary dentaries, maxillae and isolated teeth.

 Macropus
The genus Macropus includes the (eastern and western) grey kangaroo, the red kangaroo, wallaroos and some wallabies.
M. giganteus (the grey kangaroo) is an extant species. However, the grey kangaroos in the Pleistocene were much larger than their modern descendants.
M. titan is an extinct giant form of the grey kangaroo. It was flat-faced and about twice as big as the modern grey kangaroo. Some scientists regard it as a pre-dwarfing version of M. giganteus (as a sub-species, M. giganteus titan)
M. siva is a rare Macropus species from eastern Australia. Some scientists consider it a sub-species of the extant agile wallaby (M. agilis). 

Protemnodon
Protemnodon is a genus of macropods that existed in Australia and New Guinea in the Pleistocene. Based on fossil evidence it is thought that the known species were physically similar to wallabies bur far larger. They are commonly called “giant wallabies”.
P. anak was one of the biggest Protemnodons, with a weight of at least 90 kilos, while P. roechus was one of the smallest.
 

Sthenurus
Sthenurus is an extinct genus of the so-called short-faced kangaroo. The sthenurines became numerous about 2 million years ago. Fourteen species are now extinct, with a single related species (the banded hare-wallaby) surviving on two islands off the coast of Western Australia. The extinct sthenurines varied in size from quite small animals the size of a wallaby to giants which stood 2.5 metres high and weighed up to 200 kilograms. All had a single long toe with a hoof-like claw on their hind foot, a short, thick tail and long arms. Most characteristic of all, the sthenurines had short, broad faces with an expanded nasal area that may have been used for amplifying sound.
S. occidentalis was a leaf-eating kangaroo, about the size of a modern grey kangaroo. In order to grind tough leaves and shrubs it had powerful jaws and striations (sharp vertical ridges) on its teeth. The name ‘Sthenurus’ (Latin for strong-tailed) was derived from the first description of this group by Sir Richard Owen in the 19th century. He noted that the bones were undoubtedly kangaroo-like and suggestive of powerful hind limbs and strong tails.
S. gilli was a rather small sthenurine, with a body weight of about 20 kg.

 Troposodon minor
This genus lived in the Pliocene and Pleistocene. They were browsers (while most other kangaroos are grazers), some could reach a body weight of 100 kg. T. minor was its smallest member with a body weight of approximately 40 kg.
 

Diprotodontids 

Diprotodontids were adapted for life in a land of forests. They were browsers with simple premolars and ate soft vegetation. There were several species of diprotodons, which all lived in Australia. They evolved in the mid-Miocene. The smallest were about the size of a small sheep, the biggest (D. optatum) was the size of a rhino. Diprotodons, along with a wide range of other Australian megafauna, became extinct a few thousand years after humans arrived in Australia. This mass extinction was probably a result of climate change (in the late Pleistocene, the forests were replaced by deserts and grasslands), human hunting and/or human land management. 

Kolopsis torus lived in the late Miocene and was about 1.5 m long with a shoulder height of 80 cm. It was one of the first diprotodontids and relatively small. Later species were much larger.

Palorchestes parvus was characterized by retracted nasal bones, a narrow elongated rostrum and enlarged infra-orbital foramina capable of carrying large bundles of nerves and blood vessels probably supplying a trunk. It was about the size of a bull.

Zygomaturus trilobus got its name from its wide flaring zygomatic arches. The Zygomaturus species were somewhat smaller than Diprotodon, and probably favoured the forested areas of south-eastern and south-western Australia, while Diprotodon was more suited to the open grasslands of the interior. The adult Zygomaturus was about 2.5 metres long and about 1 metre high at the shoulder, with a weight of 300-500 kilograms.

Diprotodon optatum was the largest marsupial that ever lived. It was 3 m long and 2 m tall at the shoulder, weighing about two tonnes. It existed from 1.6 million years ago until about 40,000 years ago, through most of the Pleistocene era. It inhabited open forests, wood- and grasslands, eating leaves, shrubs and grasses. D. optatum was first described in the 1830s by the famous British anatomist Sir Richard Owen.

 

Thylacoleo carnifex 

T. carnifex is a member of the extinct thylacoleonid family, whose members evolved in the Oligocene and are informerly known as ‘marsupial lions’. T. carnifex was a leopard-sized marsupial very distantly related to wombats. It was first described by the distinguished British palaeontologist Sir Richard Owen in 1858. It weighed about 120 kg and was the largest mammalian predator in Australia. A study of carnivorous mammals of the world concluded that T. carnifex was the most specialised mammalian carnivore that has ever evolved, mainly because of its incredibly huge, sectorial meat-cutting premolar. It also had long sharp claws on its thumbs to grasp or slash prey. The limb proportions of Thylacoleo indicate that it could not run fast. This is probably related to the inability to run fast while carrying young in a pouch. Thylacoleo is thought to have been primarily an arboreal (tree dwelling) animal.

 

Sarcophilus 

Sarcophilus is a genus of carnivorous marsupial best known for its only living member, the Tasmanian Devil (S. harrisii). Three species are known, S. laniarius and S. moornaensis are only known from Pleistocene fossils. D. harrisii can now only be found on Tasmania, on the Australian mainland it became extinct about 600 years ago (due to predation by human-introduced dingoes and hunting by indigenous Australians). The Tasmanian Devil is now the largest carnivorous marsupial in the world (after the recent extinction of the Thylacine (‘Tasmanian Tiger’) in 1936. It is known to hunt both prey and scavenge carrion. It is a nocturnal animal. The fur is usually black, although irregular white patches on the chest and rump are common. Males are somewhat larger than females, with a head and body length of about 65 cm, a tail of 25 cm and an average weight of 8 kg. An analysis of mammalian bite force relative to the body size shows that the Tasmanian Devil has the strongest bite of any living mammal.

 Perameles

Perameles is a genus also called long-nosed bandicoots. A bandicoot is any of about 20 living species of small to medium-sized, rat-like terrestrial marsupial omnivores of the family Peramelidae. They feed on insects and plants and have a long, tapering snout and elongated hind legs.

 
Lasiorhinus 

Wombats are Australian herbivorous marsupials. They are short-legged, muscular quadrupeds, about one meter in length with a very short tail. They dig extensive burrow systems with rodent-like front teeth and powerful claws. They are mainly nocturnal animals. Their fur color can vary from a sandy color to brown, or from grey to black. There are three species, each around a meter in length and weighing between 20 and 35 kg: the Common Wombat (Vombatus ursinus), the Southern Hairy-nosed Wombat (Lasiorhinus latifrons) and the Northern Hairy-nosed Wombat (Lasiorhinus krefftii).


Bettongia leseur
 

Bettongia leseur, also known as the Boodie or Burrowing Bettong, is a small extant marsupial related to the kangaroo. It belongs to the family Potoroidae, which includes the rat-kangaroos, potoroos and other bettongs. Fossils of this family appear in the Mid-Miocene. B. leseur is a small, rat-like marsupial with short, rounded ears and a lightly-haired, thick tail. It has a pointed rostrum and beady black eyes, hind limbs longer than the forelimbs and large hind feet. It is about the size of a wild rabbit, weighing about 1.5 kg.

 
Potorus 

Potorus is a small extant marsupial also known as a Potoroo. Potoroos are the same size as rabbits. They have long feet and toes to hop and have grey fur. They come out at night to feed on seeds, fungi and insects. The potoroos weight is 1.5-2.5 kg.

 
Megalania prisca

Megalania was a giant varanid lizard also known as the Giant Goanna, that lived in the Pliocene and Pleistocene. It grew to lengths of at least 5 metres, perhaps 7. At about 600 kg, it was several times as heavy as the largest living goanna, the Komodo Dragon of Indonesia (Varanus komodensis). It was probably an ambush killer and scavenger. Megalania is known only from fragmentary material. It is the largest known land-dwelling lizard and belonged to the family that includes the goannas or monitor lizards. It appears to have become extinct around 40,000 years ago (although numerous people claim to have seen very large lizards in Australia and New Guinea in the last 100 years, suggesting Megalania is still alive). It was the largest predator in Australia during the last 2 million years. Megalania is now often put in the genus Varanus, which includes all monitor lizards.

 
Tiliqua scincoides
 

Members of the genus Tiliqua are also called blue-tongued skinks. It contains some of the largest members of the skink family. They are commonly called blue-tongued lizards in Australia, where true lizards do not naturally occur. T. scincoides is an extant species with a pale brown head with alternating streaks or blotches of dark brown and cream on its back. Its English name comes from its distinctive blue tongue. When disturbed it gapes its mouth open, sticks out its blue tongue and puffs up its body, hissing loudly. This is an effective defence mechanism, deterring many intruders.

 
Emydura

Emydura is a genus of extant turtles, also called Australian short-necked turtles. The six species of the genus Emydura are webbed-footed and semi-aquatic river turtles. They are characterized by unusually short necks.

 
Pallimnarchus pollens

Pallimnarchus is an extinct genus of crocodile from the Pliocene and Pleistocene of Australia. The genus consists of only one species, P. pollens. It was about as big as a modern saltwater crocodile. It had conical ziphodont (serrated and curved posteriorally) teeth and probably specialized in ambushing prey like kangaroos and diprotodons in shallow water.

Dromornis stirtoni 

Dromornithidae were a family of large, flightless birds that lived in Australia from the Miocene until the end of the Pleistocene. They looked a bit like very large emus or moas. Most were heavy-bodied, with powerfully developed legs and greatly reduced wings. Like other flightless birds, they lost the keel on the breastbone (sternum), that serves as the attachment for the large flight muscles. The massive, crushing beaks of some species suggest that at least some members were a combination of carnivorous predators and scavengers. D. stirtoni lived in the late Miocene and was 3 m tall and weighed about 500 kg. It was heavier than the Moa of New Zealand and taller than the Elephant Bird (Aepyornis) from Madagascar. It lived in subtropical open woodlands. For many years it was thought to have eaten mainly tough-skinned fruits and seed pods. Now, because of the shape and size of its skull and bill, some scientists think it concentrated on meat. It was the largest of the Dromornithids.

 
Pachydyptes
 

Pachydyptes is an extinct genus of penguin. It lived in the late Eocene. With a height of about 150 cm and weighing around 90 kg, it was one of the biggest penguins ever to have lived.
