A Chinese research team has discovered a partial mandible of Xenocyon lycaonoides on the Qinghai-Xizang Plateau, dating to approximately 1.95–1.77 Ma. This represents the earliest known fossil record of the species worldwide. The discovery fills a gap in the early record of X. lycaonoides in East Asian and provides key evidence for the evolution of the African wild dog–Xenocyon lineage and the "Out of Xizang" hypothesis.
