The tops of elephant bird skulls display punctuated marks, which may have been attachment sites for fleshy structures or head feathers. [18] Mullerornis is the smallest of the elephant birds, with a body mass of around 80 kilograms (180 lb), [16] with its skeleton much less robustly built than Aepyornis. [19]
In his landmark publications, such as the Systema Naturae, Carl Linnaeus used a ranking scale limited to kingdom, class, order, genus, species, and one rank below species. Today, the nomenclature is regulated by the nomenclature codes. There are seven main taxonomic ranks: kingdom, phylum or division, class, order, family, genus, and species.

Dromornis stirtoni is amongst the largest known birds, [12] although Aepyornis maximus, a species of elephant bird from Madagascar, were likely just as heavy, if not heavier. [13] The height of D. stirtoni would probably have met or exceeded the females of the tallest species of the genus Dinornis, the giant moa of New Zealand.
Birds have wings whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species ...
The largest bird in the fossil record may be the extinct elephant birds (Vorombe/Aepyornis) of Madagascar, which were related to the ostrich. They exceeded 3 m (9.8 ft) in height and 500 kg (1,100 lb) in weight. [44] The last of the elephant birds became extinct approximately 1000 years ago.
Aepyornis maximus, the "elephant bird" of Madagascar, was the heaviest bird ever known. Although shorter than the tallest moa, a large A. maximus could weigh over 400 kilograms (880 lb) and stand up to 3 metres (9 ft 10 in) tall. [ 18 ]
