物種编辑

在這個屬之下,有十個已知物種,其中八種已經絕種。There are five more possible species of which trace fossils have been found. They are:

Fossil records and egg shell fragments show that the ancestors of this genus originated about 40-58 million years ago (mya) in the Asiatic steppes as small flightless birds. The earliest fossils from this genus are from the early Miocene (20-25mya), and are from Africa, so it is proposed that they originated there. Then by the middle to late Miocene (5-13mya) they had spread to Eurasia.[5] By about 12 mya they had evolved into the larger size of which we are familiar. By this time they had spread to Mongolia and, later, South Africa.[6]
