The giant moa (Dinornis) is an extinct genus of birds belonging to the moa family. As with other moa, it was a member of the order Dinornithiformes. It was endemic to New Zealand. Two species of Dinornis are considered valid, the North Island giant moa (Dinornis novaezealandiae) and the South Island giant moa (Dinornis robustus). In addition ...
The North Island giant moa (Dinornis novaezealandiae) is an extinct moa in the genus Dinornis, known in Māori as kuranui. [4] Even though it might have walked with a lowered posture, standing upright, it would have been the tallest bird ever to exist, with a height estimated up to 3.6 metres (12 ft).
The South Island giant moa (Dinornis robustus) is an extinct species of moa in the genus Dinornis, known in Māori by the name moa nunui. [2] It was one of the tallest-known bird species to walk the Earth, exceeded in weight only by the heavier but shorter elephant bird of Madagascar (also extinct).
The North Island giant moa (Dinornis novaezealandiae) is among dozens of bird species that became extinct after the human settlement of New Zealand. This is a list of New Zealand species extinct in the Holocene that covers extinctions from the Holocene epoch, a geologic epoch that began about 11,650 years Before Present (about 9700 BCE ) [ a ...

The relatively large size of most dinosaurs and the low diversity of small-bodied dinosaur species at the end of the Cretaceous may have contributed to their extinction; [277] the extinction of the bird lineages that did not survive may also have been caused by a dependence on forest habitats or a lack of adaptations to eating seeds for survival.
The upland moa was named as Dinornis didinus in 1883 by Richard Owen from mummified material found in 1878 by H. L. Squires in Queenstown, New Zealand and subsequently sent to the British Museum. The holotype specimen consists of a mummified head and partial neck, and two mummified legs and feet which preserve the feathers.
