Name: Ctenurella ‭(‬little comb tail‭)‬.
Phonetic: Ten-u-rel-lah.
Named By: T.‭ ‬Orvig‭ ‬-‭ ‬1960.
Classification: Chordata,‭ ‬Placodermi,‭ ‬Ptyctodontida.
Diet: Carnivore.
Size: 13‭ ‬centimetres long.
Known locations: Germany.
Time period: Late Devonian.
Fossil representation: Several specimens.

       A ptyctodontid placoderm,‭ ‬the only bony armour on Ctenurella were a few bony plates that were also relatively thin.‭ ‬Ctenurella had large eyes and whip like tails which may be bottom dwelling deep water adaptations.‭ ‬This ties in with‭ ‬the analogy that Ctenurella were comparable to chimaera-like fish such as Ischyodus in their ecological niche.‭ ‬Like with other ptyctodontid placoderms like Materpiscis and Austroptyctodus,‭ ‬Ctenurella is believed to have given birth to live young rather than lay eggs in the open ocean.
