Yanliaomyzon is an extinct genus of predatory lampreys that lived approximately 163 million years ago during the Middle Jurassic. It is found in the Yanliao Biota, including both the Daohugou Beds and the Tiaojishan Formation in Liaoning province, northern China. The genus has two species: Yanliaomyzon occisor and Yanliaomyzon ingensdentes. These species are significant for being the earliest lampreys to closely resemble modern species.
