Von Mayer originally described this chimaera under the name Ischyodus avitus.
Elasmodectes avitus, a cartilaginous fish, is conspicuous for its sparsely ossified skeleton. There is a nuchal spine behind the head; the dorsal fin begins just behind the nuchal spine and extends to the tail. Elasmodectes seems to have possessed a skin or only very thin scales, which seems to be almost impossible to preserve.
The Skull is presenting its dosal view.
