About Caenolophus
Caenolophus is an extinct genus of primitive amynodont that lived in East Asia during the Middle to Late Eocene. Although Caenolophus is known only from jaw fragments, it is believed to have been anatomically intermediate between more derived amynodonts and primitive rhinocerotoids. Several species of Caenolophus have been named, with fossils found in both northern and southern China, and in North Korea.
