Haven't seen this nomen nudum mentioned on the list.
"Explorornis" Panteleyev 1999
comments- The coracoid is close to those of Gurilynia nessovi and Nanantius valifanovi. The proximal humerus is close to Wyleyia and different from Enantiornis leali and G. nessovi. The femur has a shorter neck and a wider trochanteric crest than El Brete enantiornithines. The distal femur differs from Alexornis and El Brete enantiornithines by the absence of a ridge between lateral and medial condyles, among other features.
