Adelalopus

All material included in the type specimen is considered to be from a single individual based on the proximity of the bones, their size and their similar surface texture.

[2] Unlike in Palaeolodus however the center of this element contains a deep and elongated cavity, which is regarded as one of the genus' diagnostic features.

The medial and lateral sides of the cotyla scapularis are not sharply differentiated and the foramen for the supracoracoid nerve is well-developed and elliptical like in basal-anseriforms and phoenicopteriforms.

The incomplete nature of the ulna makes comparison difficult, but it generally resembles what is expected from palaelodids and modern flamingos.

The distal vascular foramen is larger and longer than in either palaelodids or phoenicopterids and in this state more closely resembles the Eocene bird Juncitarsus, which has been recovered as either a basal member of Mirandornithes or a stem-Phoenicopteriform.

The function of the deep cavity located on the furcula is not known, it is however thought to be too large to be a simple pneumatic foramen and too small to enclose a tracheal loop.
