Megafauna. In zoology, megafauna (from Greek μέγας megas "large" and Neo-Latin fauna "animal life") are large animals. The precise definition of the term varies widely, though a common threshold is approximately 45 kilograms (99 lb), with other thresholds as low as 10 kilograms (22 lb) or as high as 1,000 kilograms (2,200 lb).
The Late Pleistocene to the beginning of the Holocene saw the extinction of the majority of the world's megafauna (typically defined as animal species having body masses over 44 kilograms (97 lb)), [1] which resulted in a collapse in faunal density and diversity across the globe. [2] The extinctions during the Late Pleistocene are ...
In zoology, megafauna (from Greek μέγας megas "large" and Neo-Latin fauna "animal life") are large animals. The most common thresholds to be a megafauna are weighing over 46 kilograms (100 lb) [ 2 ] [ 3 ] [ 4 ] (i.e., having a mass comparable to or larger than a human ) or weighing over a tonne , 1,000 kilograms (2,205 lb) [ 2 ] [ 5 ] [ 6 ...
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 ...
The term Australian megafauna refers to the megafauna in Australia [1] during the Pleistocene Epoch. Most of these species became extinct during the latter half of the Pleistocene, and the roles of human and climatic factors in their extinction are contested. There are similarities between the prehistoric Australian megafauna and some mythical ...
Megaherbivore. Hippopotamus is an extant megaherbivore. Megaherbivores (Greek μέγας megas "large" and Latin herbivora "herbivore" [1]) are large herbivores that can exceed 1,000 kg (2,200 lb) in weight. The earliest herbivores to reach such sizes like the parieasaurs appeared in the Permian period. During most of the Mesozoic, the ...
Pleistocene rewilding is the advocacy of the reintroduction of extant Pleistocene megafauna, or the close ecological equivalents of extinct megafauna. [ 1 ] It is an extension of the conservation practice of rewilding, which aims to restore functioning, self-sustaining ecosystems through practices that may include species reintroductions.
The Virginia opossum, Didelphis virginiana, the only marsupial in temperate North America. Armadillos, opossums and porcupines are present in North America today because of the Great American Interchange. Opossums and porcupines were among the most successful northward migrants, reaching as far as Canada and Alaska, respectively.
