Stegodontidae is an extinct family of Stegodon-like proboscideans that was endemic to Africa and Asia from the Miocene (15.97 mya)[1] to the Late Pleistocene, with some studies suggesting that some survived into the Holocene in China (until as recently as 4.1 thousand years ago),[2] although this is disputed.[3]
Taxonomy
Stegodontidae was named by Osborn (1918). It was assigned to Mammutoidea by Carroll (1988); to Elephantoidea by Lambert and Shoshani (1998); and to Elephantoidea by Shoshani et al. (2006).[4][5] It contains two of extinct elephant-like genera:

Like all Proboscideans, the clade's position is uncertain: Some authors place it as a daughter clade under the Elephantidae, while others make the Stegodontidae a sister-clade to the Elephantidae.
