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
Elephant Island be found, and chinstrap penguins nest in season. A lack of safe anchorage has prevented any permanent human settlement, despite the island being well placed to support scientific, fishing and whaling activities. Elephant Island's name can be attributed to both its elephant head-like appearance and the sighting of elephant seals by Captain George Powell in 1821, one of the earliest sightings.
