What is "stegodon"

Stegodon (meaning "roofed tooth" from the Greek words στέγειν stegein 'to cover' and ὀδούς odous 'tooth') is a genus of the extinct subfamily Stegodontinae of the order Proboscidea. It was assigned to the family Elephantidae (Abel, 1919), but has also been placed in Stegodontidae (R. L. Carroll, 1988). Stegodonts were present from 11.6 mya to late Pleistocene, with unconfirmed records of regional survival until 4,100 years ago. Fossils are found in Asian and African strata dating from the late Miocene . They lived in large parts of Asia, East and Central Africa and North America during the Pleistocene.
