1、长毛象mammoth(猛犸)

2、A mammoth is any species of the extinct genus Mammuthus. These proboscideans are members of Elephantidae, the family of elephants and mammoths, and close relatives of modern elephants. They were often equipped with long curved tusks and, in northern species, a covering of long hair. They lived from the Pliocene epoch from around 4.8 million to 4,500 years ago.The word mammoth comes from the Russian мамонт mamont, probably in turn from the Vogul (Mansi) language.

3、Like their modern relative the elephant, mammoths were quite large; in English the noun "mammoth" has become an adjective meaning "huge" or "massive". The largest known species, Songhua River Mammoth (Mammuthus sungari) , reached heights of at least 5 meters (16 feet) at the shoulder. Mammoths would probably normally weigh in the region of 6 to 8 tonnes, but exceptionally large males may have exceeded 12 tonnes. An 11-foot (3.4 m) long mammoth tusk was discovered north of Lincoln, Illinois in 2005. However, most species of mammoth were only about as large as a modern Asian Elephant. Fossils of species of dwarf mammoth have been found on the Californian Channel Islands (Mammuthus exilis) and the Mediterranean island of Sardinia (Mammuthus lamarmorae). There was also a race of dwarf woolly mammoths on Wrangel Island, north of Siberia, within the Arctic Circle.

4、Based on studies of their close relatives the modern elephants, mammoths probably had a gestation period of 22 months, resulting in a single calf being born. Their social structure was probably the same as that of African and Asian elephants, with females living in herds headed by a matriarch, whilst bulls lived solitary lives or formed loose groups after sexual maturity.
