Caproberyx

Caproberyx is an extinct genus of marine acanthomorph ray-finned fish, possibly a holocentrid, from the Late Cretaceous.

Other former species found in Lebanon (C. pharsus) and Morocco (C. polydesmus) have been assigned to their own genera (Pattersonoberyx and Stichoberyx respectively).

[1][2][3] Potential remains of an indeterminate species have also been found in the Smoky Hill Chalk of Kansas, USA.

[3] However, more recent studies have recovered it as an indeterminate acanthomorph, and possibly most closely related to the Trachichthyiformes.

[7] The species name superbus references the exceptional nature of some specimens, consisting of three-dimensionally preserved mass death assemblages with mouths open in tetany.
