ratite

This ratite is the largest bird in the Americas.

It is the fifth heaviest living bird species, after only the larger varieties of ratite.

Heterorhea is an extinct genus of ratite in the rhea family.

Diogenornis is an extinct genus of ratite which lived during the Paleocene.

The African Ostrich is the largest living ratite.

The only ratite in the country and the largest bird in the world is the Common Ostrich.

Huxley believed that birds evolved from an ancestral ratite, and the large Massachusetts tracks seemed to support this.

Its toes, however, differed vastly in shape and posture from those of this ratite (and most other birds).

Other scientists are less convinced that Palaeotis is a struthioniform, placing it instead as a more basal ratite.

Some of the first remains of the massive Dasornis were mistaken for a ratite's and later a diatryma's.

Economic prosperity is good news for the endangered West African ratite, the Ghana Rhea.

A ratite is any of a diverse group of large, flightless birds of the superorder Palaeognathae.

Struthio linxiaensis is an extinct species of ratite from the Miocene of China.

- Incognitoolithus (Eocene of North America) - ratite?

Subsequent authors, noting that it was quite obviously not a paleognath ratite, placed Dasornis in the Gastornithidae (diatrymas).

Like the cassowary, ostrich, rhea, emu and kiwi, Aepyornis was a ratite; it could not fly, and its breast bone had no keel.

It was initially assumed to be a flightless paleognathe bird, possibly a ratite, and later as a more primitive ornithuromorph or non-avialan theropod (Benton et al., 1997).

- Namornis (Middle Miocene of Namibia - Late Miocene of Kenya) - ratite?

The Little Spotted Kiwi is a ratite and belongs to the Apterygiormes Order, and the Apterygidae Family.

If Remiornis is indeed correctly identified as a ratite (which is quite doubtful however), Gastornis remains as the only known animal that could have laid these eggs.

The tarsometatarsus is also more similar to that of an unspecific ratite, such as an emu, ostrich or rhea, rather than to the apomorphic one of the elephantbirds.

Ratite chicks tend to be more omnivorous or insectivorous; similarities in adults end with feeding, as they all vary in diet and length of digestive tract, which is indicative of diet.

The details (such as lack of the supratendinal bridge) may however be simply plesiomorphies, while the overall resemblance might be the result of convergent evolution-for the autapomorphies of its toes are starkly unlike those found in any ratite.

Technically, the latter is incorrect because it has recently been found not to be a megapode, but the sole known member of its own family, the Sylviornithidae; at the time of its description, it was believed to be a ratite.

If Palaeotis is, as Houde and Haubold suggested a basal or even ancestral ostrich, it would be the only ratite known from the Northern hemisphere at this early age, and this has important implications for the evolution of ratites.
