Shoulder girdle and forelimb elements.
Gurilynia nessovi collected in 1994 was a large enantiornithid characterized by the almost equal length of the ventral and dorsal portions of the humeral articular head, a very shallow cranial fossa in the middle of the proximal area of the cranial surface of the proximnal end of the humerus, the thick base of the deltopectoral crest, a very shallow caudal depression in the caudal surface of the proximal end of the humerus, the pointed ventral termination of the processus coracoideus, and a remarkably thin coracoidal neck between the shoulder end of the shaft. The width of the proximal end of the humerus is 26,2 mm distinctly larger than Enantiornis leali.
