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 ...
Megafauna also play a role in regulating and stabilizing the abundance of smaller animals. During the Pleistocene, megafauna were diverse across the globe, with most continental ecosystems exhibiting similar or greater species richness in megafauna as compared to ecosystems in Africa today.
An African bush elephant (Loxodonta africana), is an example of charismatic megafauna. Charismatic megafauna are animal species that are large—in the category that they represent [1] —with symbolic value or widespread popular appeal, and are often used by environmental activists to gain public support for environmentalist goals.

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 ...

Today, you can only find Javan rhinos in one place on Earth, the Ujung Kulon National Park in Indonesia. Over Around 2,000 years ago, they were still common in many parts of China.
Marine biologists have captured a rare sight of a giant pod of over 1,500 dolphins leaping and swimming off the California coast.. The “super pod” of Risso’s dolphins was spotted in Carmel ...
Pleistocene America boasted a wide variety of carnivores (most of which are extinct today), such as the short-faced bear, saber-toothed cats (e.g. Homotherium and Smilodon), the American lion, dire wolf, and the American cheetah.
