Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| G. Mayr and A. C. Kitchener 2024 | Small stem group Galliformes with a
deeply excavated cotyla scapularis (coracoid) of circular shape. This feature distinguishes the new taxon from the Gallinuloididae as exemplified by the type genus Gallinuloides, in which the cotyla scapularis has an ellipsoid outline. The proximal humerus has a distinctive morphology and is distinguished from that of the Gallinuloididae (as exemplified by Paraortygoides messelensis; the feature is not observable in Gallinuloides), Quercymegapodiidae, Paraortygidae, and crown group Galliformes in a proximodistally narrower caput humeri and a shorter and wider tuberculum dorsale, which reaches only slightly farther distally than the tuberculum ventrale. |
