Rajorhina is an extinct genus[2] of stingray-like skate from the Upper Cretaceous of what is now Lebanon.[3][1] It is the only known fossil-only genus of the family Rajidae[4] The genus is typified by a Rhombus form.[citation needed]

From its taxonomy a few things have been inferred about it. It likely lived in a marine environment and it was phosphatic based on its subphylum.[2] It was actively mobile and a carnivore.[2]
