About Yantanglestes
Yantanglestes is a genus of small, Chinese mesonychid with slender jaws that first appeared during the Early Paleocene. It was found throughout Asia. It is the oldest known mesonychid. Yantanglestes became extinct during the Nongshanian division of the Middle Paleocene, and lived sympatrically with its descendant genera, including Dissacus, Sinonyx and Jiangxia.
