/ˌdɹɒmiːˈɒɡnəθəs/ · adjective
(ornithology) Possessing a palatal structure akin to the emu and the other (now extinct) species of the genus Dromaius..
Ægithognathous.—One of the four types of palatal structure distinguished by Huxley. The Dromæognathous type, with large vomer,¹ found in Ratites (Ostrich-like birds) is sharply defined from the others (in which the vomer is more or less reduced), but the latter are by no means so clearly separated from one another, and are connected to a great extent by intermediate conditions.
The fourth principal type, the dromæognathous, is not found in any Indian birds.
From the fact that the dromæognathous skull is more reptilian than any other type, it would seem that the Ratitæ diverged early from the carinate stock.
It is well known that the membrane bones of the ostrich palate have a dromæognathous arrangement which is closer to the lacertilian plan than to the characteristic bird type where palatines and pterygoids slide upon a central rostrum.
Use dromaeognathous when its meaning, tone and grammar fit the full sentence. A synonym is not always a direct replacement.
Dromaeognathous means (ornithology) Possessing a palatal structure akin to the emu and the other (now extinct) species of the genus Dromaius..
The closest synonym depends on the sentence and intended sense.
