A mammoth is any species of the extinct elephantid genus Mammuthus. They lived from the late Miocene epoch (from around 6.2 million years ago) into the Holocene until about 4,000 years ago, with mammoth species at various times inhabiting Africa, Asia, Europe, and North America.

2025年3月9日 · Mammoth, any member of an extinct group of elephants found as fossils in Pleistocene and Holocene deposits on several continents. The woolly, Northern, or Siberian mammoth (Mammuthus primigenius) is by far the best-known of all mammoths and may have persisted as late as 4,300 years ago.

Mammatus (also called mamma[1] or mammatocumulus, meaning "mammary cloud") is a cellular pattern of pouches hanging underneath the base of a cloud, typically a cumulonimbus raincloud, although they may be attached to other classes of parent clouds. The name mammatus is derived from the Latin mamma (meaning "udder" or "breast").

Mammoth is the common name for any of the large, extinct elephants comprising the genus Mammuthus, with many species equipped with long, curved tusks, and in northern species, a covering of long hair. As members of Elephantidae (elephant family), they are close relatives of modern elephants and in particular the Asian elephant (Elephas maximus).

Two million years ago, during the Pleistocene epoch, an immense beast with long, shaggy hair and huge, curved tusks lumbered around what are now Africa, Eurasia, and North America. This animal, the mammoth, was the ancestor of the modern elephant. Mastodons, similar in appearance to mammoths, were early distant relatives of the mammoths.
