Orienspterodon ("eastern Pterodon") is an extinct genus of hyainailourid hyaenodonts from paraphyletic subfamily Hyainailourinae that lived in China and Myanmar^[4] during the middle to late Eocene. Orienspterodon dahkoensis was originally assigned to genus Pterodon in 1975, but was eventually assigned to its own genus in 2007.^[1]
