Orodus (from Greek: ωραίος oraíos, 'beautiful' and Greek: ὀδούς odoús 'tooth')[1] is an extinct genus of cartilaginous fish that lived from the late Pennsylvanian to the early Permian in what is now North America. O. greggi reached around 2–4 metres (6.6–13.1 ft) long, while O. micropterygius just reached 1 metre (3.3 ft).[2][3] It was a member of the holocephali subclass, meaning that it was more closely related to chimaeras and their relatives (eugeneodonts, petalodonts, etc), and not elasmobranchs like sharks and rays.
