Cryptoberyx Explained

Cryptoberyx is an extinct genus of prehistoric marine ray-finned fish that lived during the late Cenomanian stage of the Late Cretaceous.^{[1] [2]} Two species are known from southern Europe and the Middle East, both part of the former Tethys Sea.

The following species are known:^{[3] [4]}

• †C. minimus Gaudant, 1978 (type species) - Cenomanian of Lebanon (Sannine Formation)
• †C. brevis Gaudant, 1978 - Cenomanian of Portugal

The holotype of C. minimus was initially used by Arthur Smith Woodward as a paratype of Lissoberyx dayi, until later studies found it to represent a different genus entirely.

Cryptoberyx was previously considered a beryciform under a former paraphyletic view of the order (which also included the Trachichthyiformes and Holocentriformes), as a stem-group "trachichthyoid".^[5] With the splitting of these two orders, its taxonomic identity is unclear.^[6]
