Stegodontidae is an extinct family of proboscideans from Africa and Asia (with a single occurrence in Europe) from the Early Miocene (at least 17.3 million years ago[1]) to the Late Pleistocene.[2] It contains two genera, the earlier Stegolophodon, known from the Miocene of Asia and the later Stegodon, from the Late Miocene to Late Pleistocene of Africa and Asia (with a single occurrence in Greece) which is thought to have evolved from the former. The group is noted for their plate-like lophs on their teeth, which are similar to elephants and different from those of other extinct proboscideans like gomphotheres and mammutids, with both groups having a proal jaw movement utilizing forward strokes of the lower jaw. These similarities with modern elephants were probably convergently evolved.[1] Like elephantids, stegodontids are thought to have evolved from gomphothere ancestors.[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] While Stegodon was historically considered an elephant, this is now largely rejected, with the similarities considered to be convergent.[1]
