 Hay 1902, originally Holoptychius quebecensis Whiteaves 1889; Schultze and Arenault 1987; Late Devonian, up to 60cm in length, Figs 1, 2) was originally considered a porolepiform, but here the bullet-skull specimen nests with Cheiroleips. Like Cheirolepis, the fore fin is lobed, but the pelvic fin is not. Note the dorsal and anal fins are also not lobed, distinct from Holoptychius and other lobe-finned taxa in the Porolepiformes.
