Juchilestes

Juchilestes is an amphidontid^[1] mammal genus from the early Cretaceous (early Aptian stage, 123.2 ± 1.0 Ma). It lived in what is now the Beipiao of western Liaoning, eastern China. It is known from the holotype D2607, which consists of three-dimensionally preserved, partial skull with mandibles and some teeth. It was found in 2004 from the Lujiatun Site of the Yixian Formation (Jehol Biota). It was first named by Chun-Ling Gao, Gregory P. Wilson, Zhe-Xi Luo, A. Murat Maga, Qingjin Meng and Xuri Wang in 2010 and the type species is Juchilestes liaoningensis.^[2]
