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 ...
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 extraterrestrial impact, which has occasionally been proposed as a cause of the Younger Dryas, [219] has been suggested by some authors as a potential cause of the extinction of North America's megafauna due to the temporal proximity between a proposed date for such an impact and the following megafaunal extinctions.
Fossilized specimens were primarily found in South and North America, with one specimen being found as far north as Alaska. [28] Mammoths, like modern day elephants, had hypsodont molars. These features allowed mammoths to live an expansive life because of the availability of grasses and trees. [29] Today, nine of the 50 species persist.
The Javan rhino (Rhinoceros sondaicus) once roamed across many countries in Southeast Asia. Around 2,000 years ago, they were still common in many parts of China. Around 12,000 years ago, they ...
Map of North America. This is a list of North American animals extinct in the Holocene that covers extinctions from the Holocene epoch, a geologic epoch that began about 11,650 years before present (about 9700 BCE) [A] and continues to the present day. [1] Recently extinct animals in the West Indies and Hawaii are in their own respective lists.
