Sinohelicoprion (meaning "Chinese spiral saw" or "Chinese Helicoprion") is an extinct genus of helicoprinid eugeneodontid fish that lived during the late Permian and possibly the Early Triassic, from 254 to 251 million years ago.[1][2]

It was first named and classified by H. T. Liu and M. N. Chang in 1963.[3][4]
