Paleocadmus is a genus of radula known only from the Mazon Creek biota. It is only known from isolated fossils around a centimetre in length, and a few mm wide (in one instance associated with a possible beak), but its morphology aligns it with the nautiloids, or perhaps the bactritoids or belemnoids.[1]
