Megalania (Varanus priscus) is an extinct species of giant monitor lizard, [1] part of the megafaunal assemblage that inhabited Australia during the Pleistocene. It is the largest terrestrial lizard known to have existed, but the fragmentary nature of known remains make estimates highly uncertain. Recent studies suggest that most known ...
Some mammals declared as extinct may very well reappear. [1] For example, a study found that 36% of purported mammalian extinction had been resolved, while the rest either had validity issues (insufficient evidence) or had been rediscovered. [3] As of December 2015, the IUCN listed 30 mammalian species as "critically endangered (possibly ...
A 2021 study found that the rate of extinction of Australia's megafauna is rather unusual, with some more generalistic species having gone extinct earlier while highly specialised ones having become extinct later or even still surviving today. A mosaic cause of extinction with different anthropogenic and environmental pressures was proposed. [24]

Thylacoleo ("pouch lion") is an extinct genus of carnivorous marsupials that lived in Australia from the late Pliocene to the Late Pleistocene (until around 40,000 years ago), often known as marsupial lions. They were the largest and last members of the family Thylacoleonidae, occupying the position of apex predator within Australian ecosystems ...
Extinctions in northern Eurasia were staggered over tens of thousands of years between 50,000 and 10,000 years ago, [2] while extinctions in the Americas were virtually simultaneous, spanning only 3000 years at most. [4][8] Overall, during the Late Pleistocene about 65% of all megafaunal species worldwide became extinct, [9] rising to 72% in ...
The dugong (/ ˈ d (j) uː ɡ ɒ ŋ /; Dugong dugon) is a marine mammal.It is one of four living species of the order Sirenia, which also includes three species of manatees.It is the only living representative of the once-diverse family Dugongidae; its closest modern relative, Steller's sea cow (Hydrodamalis gigas), was hunted to extinction in the 18th century.
The Australian continent, also called Australia-New Guinea or Sahul. The thylacine (Thylacinus cynocephalus) is a large, carnivorous marsupial last seen in 1936. This is a list of Australia-New Guinea species extinct in the Holocene that covers extinctions from the Holocene epoch, a geologic epoch that began about 11,650 years before present ...
