The holotype, Chagrinia enodis, was found eroded out of the Chagrin Shale in the Euclid Creek Reservation in Cleveland, Ohio, in 1960 by a local citizen.[1][2]

The fossil material is poorly preserved, but the species appears to exhibit a slender boy, narrow caudal peduncle, symmetrical tail, and fin rays that outnumber the endochondral supports. The scales appeared to be unornamented, but that may be a preservational artefact.[3]
