Elephant bird process of continental drift. Claims of findings of "aepyornithid" egg remains on the eastern Canary Islands, if valid, would represent a major biogeographical enigma. These islands are not thought to have been connected to mainland Africa when elephant birds were alive. There is no indication that elephant birds evolved outside Madagascar, and today, the Canary Island eggshells are considered to belong to extinct North African birds that may not have been ratites (possibly "Eremopezus"/"Psammornis", or even Pelagornithidae, prehistoric seabirds of immense size). Various "aepyornithid-like" eggs and bones occur in Paleogene and Miocene deposits in Africa and Europe. Two whole eggs

The African elephant was first named by German naturalist Johann Friedrich Blumenbach in 1797 as "Elephas africanus". The genus "Loxodonta" was named by Frédéric Cuvier in 1825. Cuvier spelled it "Loxodonte," but in 1827 an anonymous author romanised the spelling to "Loxodonta"; the International Code of Zoological Nomenclature recognises this as the proper authority. In 1942, 18 subspecies of African elephant were recognised by Henry Fairfield Osborn, but further morphological data has reduced the number of classified
