Giraffoidea

Giraffoidea is a superfamily that includes the families Climacoceratidae, Prolibytheriidae, and Giraffidae. The only extant members in the superfamily are the giraffes and okapi. The Climacoceratidae are also placed in the superfamily, but were originally placed within the family Palaeomerycidae.

Climacoceratidae is a family of superficially deer-like artiodactyl ungulates which lived in the Miocene epoch in Africa. They are close to the ancestry of giraffes, with some genera, such as Prolibytherium, originally classified as giraffes, but later found to have been of entirely different families.
