Dinornis

 

a genus of extinct birds of the order Dinornithiformes. Remains of Dinornis are known from the Pleistocene and Quaternary deposits of New Zealand. There are five species. Members of the genus grew to a height of 3 m and, with the Madagascar Aepyornis, were the largest birds of prey. Their eggs weighed as much as 8 kg. Like the Aepyornis, Dinornis was exterminated by man in the 18th century.

Overall, Dinornis moas exhibit a difference between the sexes in average size and weight that outranks that of all other birds and probably that of any terrestrial animal, says Cooper.
