Diagnoza

Differential diagnosis - Small passerine, approximately the size of a Blue Tit Cyanistes (Parus) caeruleus.
The specimen differs from:
• All extant Passeriformes in the unique combination of the following characters: only five (six?) caudal vertebrae; sternum with trabecula mediana that does not widen in its caudal part, and with long processus craniolateralis that projects further anterior than the labrum dorsale; very stout humerus with a undulated dorsal margin of crista deltopectoralis and with proximal part broad dorso-ventrally; os carpi ulnare with crus breve and crus longum of approximately similar size.

• The early Oligocene Wieslochia weissi in: coracoid with hooked processus acrocoracoideus and reduced processus procoracoideus; carpometacarpus with broad square distal end of the os metacarpale minus that protrudes far distally.

• The early Oligocene Jamna szybiaki in: only five (six?) caudal vertebrae; sternum with bifurcated spina externa; coracoid with hooked processus acrocoracoideus; humerus with short crista deltopectoralis; carpometacarpus with less stout os metacarpale majus; pelvis with margo cranialis and margo lateralis of ala preacetabularis ilii meeting at a wide angle.

• The extinct passerine-like family Zygodactylidae in: coracoid with hooked processus acrocoracoideus and short and rounded processus lateralis; sternum with bifurcated spina externa and a single pair of incisions in its caudal part; ulna with a prominent olecranon that projects far proximally and tapers; carpometacarpus with a broad distal end of the os metacarpale minus that protrudes far distally; phalanx digiti alulae does not bear an ungual phalanx; phalanx distalis digiti majoris much shorter than the phalanx proximalis.

Porównanie

Resoviaornis jamrozi was a very small bird the size of a Blue Tit Cyanistes (Parus) caeruleus or a Chiffchaff P. collybita. It was smaller than Wieslochia which was the size of a House Sparrow (Mayr and Manegold 2006a) and Jamna which was the size of a Skylark (Bochenski et al. 2011).
