Diagnosis
Reference | Diagnosis | |
---|---|---|
Z. M. Bochenski et al. 2019 | A member of Charadrii, approximately the size of extant Haematopus ostralegus that differs from
all genera by the following combination of characters of the coracoid: robust processus acrocoracoideus with cranio-sternal length about the same as medial projection; the foramen nervi supracoracoidei is very close to the sternal margin of the cotyla scapularis (only in Haematopus is this foramen similarly close, yet is still more widely separated); the medial margin of the facies articularis humeralis is straight almost along its entire length; and sternally, the angulus lateralis is broad with sternal and lateral margins meeting almost at right angles; and on which the dorsal edge of the facies articularis sternalis connects to the angulus lateralis. |
