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 ...
Among living animals, the term megafauna is most commonly used for the largest extant terrestrial mammals, which includes (but is not limited to) elephants, giraffes, hippopotamuses, rhinoceroses, and larger bovines.
The extermination of megafauna left many niches vacant, which has been cited as an explanation for the vulnerability and fragility of many ecosystems to destruction in the later Holocene extinction. The comparative lack of megafauna in modern ecosystems has reduced high-order interactions among surviving species, reducing ecological complexity ...
Extant megaherbivores are large megafaunaul herbivores that can exceed 1,000 kg (2,200 lb) in weight. They include elephants, rhinos, hippos, and giraffes, and are the largest of the land animals.
There was a population living in Vietnam, but the last one died in 2011. The park has been monitoring the population since 1967 when there were only 25 rhinos. Park officials estimated the herd ...

The most common thresholds to be a megafauna are weighing over 46 kilograms (100 lb) (i.e., having a mass comparable to or larger than a human) or weighing over a tonne, 1,000 kilograms (2,205 lb) (i.e., having a mass comparable to or larger than an ox).
As part of the Late Pleistocene megafauna extinctions, 80% of megaherbivore species became extinct, with megaherbivores becoming entirely extinct in Europe, Australia and the Americas. Recent megaherbivores include elephants, rhinos, hippos, and giraffes. There are nine extant species of terrestrial megaherbivores living in Africa and Asia.

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.
