These include "Eremopezus" from the Eocene of North Africa, unnamed Canary Island remains and several Neogene taxa in Eurasia. "Aepyornis maximus" is commonly known as the 'elephant bird', a term

Heard Island is isolated, uninhabited and rarely visited. When the island was visited in 2002 and 2003 by scientists from the Australian Antarctic Division, the spit was intact. However, a following visit in late 2008 found that a section of the eastern end of the spit had become inundated by the ocean, forming a 2-km-long island. Elephant Spit Elephant Spit is a 9 km
