Etymology: Sino (Latin), China; delphys (Greek), uterus, commonly used suffix for marsupial taxa; szalayi, in honor of F. S. Szalay for his studies of metatherian evolution. Systematics; Class Mammalia, Subclass Metatheria, Order and Family incertae sedis. Holotype: CAGS00-IG03 (Fig. 1; Chinese Academy of Geological Sciences, Institute of Geology), an incomplete, flattened skeleton with some preserved soft tissues, such as costal cartilages and fur, on a shale slab; parts of hindlimb, pes, and shoulder girdle preserved on fragments of a counterslab. Locality and age: lacustrine beds of the Yixian Formation at the Dawangzhangzi Locality, Lingyuan County, Liaoning, China. The locality is correlated with the main fossiliferous horizon of the Yixian at the Sihetun site that was dated as 124.6 Ma (12) in the lower Barremian stage of the Lower Cretaceous.

Diagnosis: Upper 14, C1, P4, M4; lower i4, c1, p4, m3 (Fig. 1). Sinodelphys szalayi differs from most mammaliaforms (2), eutriconodonts (8, 9), and multituberculates (2, 11) in having triangulated molar cusps; differs from zhangheotheriids and all pretribsophenic mammals in having a tricuspate talonid basin; differs from all known eutherians in having compressed, lanceolate posterior incisors, four (instead of three) upper molars, and apomorphies of the ankle and wrist; and differs from all known metatherians in dental formula. For full differential diagnosis, see (14).
