Aepyornis
Aepyornis is a genus of aepyornithid, one of three genera of ratite birds endemic to Madagascar until their extinction sometime around AD 1000. The species A. maximus weighed up to 540 kilograms (1,200 lb), and until recently was regarded as the largest known bird of all time. However, in 2018 the largest aepyornithid specimens, weighing up to 730 kilograms (1,600 lb), were moved to the related genus Vorombe.read more
