The Lecho Formation preserves many enantiornithine bones, most
disarticulated. The proximal scapula, coracoid and humerus of Enantiornis
(PVL-4035) were found articulated. Chiappe (1996) refers five more
specimens to the species- (PVL-4020) several pectoral and forelimb elements;
(PVL-4023) ulna; (PVL-4039) scapula; (PVL-4055) scapula; (PVL-4181) ulna.
There are apparently at least five taxa represented- one small (unnamed),
three medium (Lectavis, Yungavolucris, Soroavisaurus), and one large
(Enantiornis). The only cranial element is the posterior portion of a
mandible, which is undescribed. Whether this has teeth, or is even complete
enough to indicate if it does, is unknown.
