Diprotodon is an extinct genus of large marsupials native to Australia from the Pleistocene epoch. It is considered one of Australia's core species of "megafauna", which ranged throughout the continent during the Pleistocene. The genus is currently considered monotypic, containing only Diprotodon optatum, the largest known marsupial to have ever existed. The word diprotodon is constructed from the Ancient Greek words for 'two forward teeth'. Diprotodon existed from about 1.6 million years ago until extinction some 44,000 years ago.
Obdurodon is a genus of extinct monotreme. They appeared much like their modern day relative the platypus, except adults retained their molar teeth. Unlike the platypus which forages on the lakebed, Obdurodon may have foraged in the water column or surface.
The order Peramelemorphia includes the bandicoots and bilbies; it equates approximately to the mainstream of marsupial omnivores. All members of the order are endemic to the twin land masses of Australia-New Guinea and most have the characteristic bandicoot shape: a plump, arch-backed body with a long, delicately tapering snout, very large upright ears, relatively long, thin legs, and a thin tail. Their size varies from about 140 grams up to 4 kilograms, but most species are about one kilogram, or the weight of a half-grown kitten.
The dire wolf is an extinct canine. It is one of the most famous prehistoric carnivores in North America, along with its extinct competitor Smilodon. The dire wolf lived in the Americas and eastern Asia during the Late Pleistocene and Early Holocene epochs. The species was named in 1858, four years after the first specimen had been found. Two subspecies are recognized: Aenocyon dirus guildayi and Aenocyon dirus dirus. The largest collection of its fossils has been obtained from the Rancho La Brea Tar Pits in Los Angeles.
Zhoukoudian Peking Man Site (周口店北京人遗址), also romanized as Choukoutien, is a cave system in suburban Fangshan District, Beijing. It has yielded many archaeological discoveries, including one of the first specimens of Homo erectus, dubbed Peking Man, and a fine assemblage of bones of the gigantic hyena Pachycrocuta brevirostris.
Thylacoleo is an extinct genus of carnivorous marsupials that lived in Australia from the late Pliocene to the late Pleistocene. Some of these marsupial lions were the largest mammalian predators in Australia of their time, with Thylacoleo carnifex approaching the weight of a lioness. The estimated average weight for the species ranges from 101 to 130 kg.
Gigantopithecus is an extinct genus of ape from the Early to Middle Pleistocene of southern China, represented by one species, Gigantopithecus blacki. Potential identifications have also been made in Thailand, Vietnam, and Indonesia. The first remains of Gigantopithecus, two third molar teeth, were identified in a drugstore by anthropologist Ralph von Koenigswald in 1935, who subsequently described the ape. In 1956, the first mandible and over 1,000 teeth were found in Liucheng, and numerous more remains have since been found in at least 16 sites. Only teeth and four mandibles are known currently, and other skeletal elements were likely consumed by porcupines before they could fossilise. Gigantopithecus was once argued to be a hominin, a member of the human line, but it is now thought to be closely allied with orangutans, classified in the subfamily Ponginae.
Procoptodon is an extinct genus of giant short-faced kangaroos that lived in Australia during the Pleistocene Epoch. P. goliah, the largest known kangaroo species that ever existed, stood at about 2 m (6.6 ft). They weighed about 200–240 kg (440–530 lb). Other members of the genus are smaller, however; Procoptodon gilli is the smallest of all of the sthenurine kangaroos, standing approximately 1 m tall.
Sthenurinae is a subfamily within the marsupial family Macropodidae, known as 'short faced kangaroos'. No members of this subfamily are extant today, with all becoming extinct by the late Pleistocene. Procoptodon goliah, the largest macropodid known to have existed, was a sthenurine kangaroo, but sthenurines occurred in a range of sizes, with Procoptodon gilli being the smallest at the size of a small wallaby.
Palorchestes is an extinct genus of terrestrial, herbivorous marsupials of the family Palorchestidae. The genus was endemic to Australia, living from the Miocene through to the Pleistocene epochs.
Sthenurus is an extinct genus of kangaroos. With a length around 3 m (10 ft), some species were twice as large as modern extant species. Sthenurus was related to the better-known Procoptodon. The subfamily Sthenurinae is believed to have separated from its sister taxon, the Macropodinae, halfway through the Miocene, and then its population grew during the Pliocene.
Thylacoleo carnifex, also known as the "marsupial lion", is an extinct species of carnivorous marsupial mammal that lived in Australia from the early to the late Pleistocene. Despite its name, it is not closely related to the lion but is a member of the order Diprotodontia, one of the taxonomic groups of Australian marsupials.
Simosthenurus, also referred to as the short-faced kangaroo, is an extinct genus of megafaunal macropods that existed in Australia, specifically Tasmania, during the Pleistocene. Analysis of Simosthenurus fossils has contributed to the finding that there are three lineages of macropods: Sthenurinae, Macropodinae, and Lagostrophinae. The genus Simosthenurus was among the sthenurines.
The Jamaican fig-eating bat is a species of bat in the family Phyllostomidae. It is the only living species in the genus Ariteus. The scientific name translates as "yellowish and warlike". There are no recognised subspecies.
Durophagy is the eating behavior of animals that consume hard-shelled or exoskeleton bearing organisms, such as corals, shelled mollusks, or crabs. It is mostly used to describe fish, but is also used when describing reptiles, including fossil turtles, placodonts and invertebrates, as well as "bone-crushing" mammalian carnivores such as hyenas. Durophagy requires special adaptions, such as blunt, strong teeth and a heavy jaw. Bite force is necessary to overcome the physical constraints of consuming more durable prey and gain a competitive advantage over other organisms by gaining access to more diverse or exclusive food resources earlier in life. Those with greater bite forces require less time to consume certain prey items as a greater bite force can increase the net rate of energy intake when foraging and enhance fitness in durophagous species. In the order Carnivora there are two dietary categories of durophagy; bonecrackers and bamboo eaters. Bonecrackers are exemplified by hyenas and saber-toothed cats, while bamboo eaters are primarily the giant panda and the red panda. Both have developed similar cranial morphology. However, the mandible morphology reveals more about their dietary resources. Both have a raised and dome-like anterior cranium, enlarged areas for the attachment of masticatory muscles, enlarged premolars, and reinforced tooth enamel. Bamboo eaters tend to have larger mandibles, while bonecrackers have more sophisticated premolars.
Malleodectes is a genus of unusual marsupial species, first discovered in 2011 at Riversleigh, Queensland, Australia. It could grow as large as a ferret, and lived in the Miocene, 17 million years ago. The reason for its name, which means "Hammer Biter", is because it has blunt, hammer like teeth, not known from any other mammal extant or extinct. However, Scott Hocknull from the Queensland Museum has noticed similarities to the modern pink-tongued skink, a reptile specialised for eating snails. This suggests that Malleodectes too was a specialised snail hunter.
Fossil Cave (5L81), formerly known as The Green Waterhole, is a cave in the Limestone Coast region of south-eastern South Australia. It is located in the gazetted locality of Tantanoola about 22 kilometres north-west of the city of Mount Gambier, only a few metres from the Princes Highway between Mount Gambier and Millicent. It is notable both as a paleontological site and as a cave diving site.
Ursus dolinensis is an extinct mammalian carnivore species of the Ursidae family. Its fossilized remains were unearthed from the lowest layers of the stratigraphic sequence at the archaeological and paleontological site of Gran Dolina, that is a part of the Atapuerca Mountains complex in the Burgos province, northern Spain. The species was described by Nuria Garcia and Juan Luis Arsuaga in a 2001 publication. Skeletal fossils, mainly cranial fragments were recovered from the sediment units TD 3 and in particular TD 4. Presence in these layers suggests a chronology in between 900,000 and 780,000 years ago, which falls into the Calabrian stage of the early Pleistocene.
Macroderma koppa is a species of bat known from fossil material found in Australia, one of the larger carnivorous megadermatid family of the order Chiroptera. They resembled the modern species Macroderma gigas, known as a false vampire or ghost bat, and also preyed on vertebrates such as small mammals, reptiles and bird, and amphibian species, whose butchered remains were found beneath their feeding roosts.
Ekaltadeta ima is a species of potoroid marsupial that existed in Miocene Australia.
