African elephants are elephants of the genus Loxodonta. The genus consists of two extant species: the African bush elephant, L. africana, and the smaller African forest elephant, L. cyclotis. Loxodonta (from Greek λοξός, loxós: 'slanting, crosswise, oblique sided' + ὀδούς, odoús: stem odónt-, 'tooth') is one of two existing genera of the family Elephantidae. Fossil remains of Loxodonta have been found only in Africa, in strata as old as the middle Pliocene. However, sequence analysis of DNA extracted from fossils of the extinct straight-tusked elephant undermines the validity of the genus.
