Eocottus
Eocottus is an extinct genus of prehistoric marine ray-finned fish that lived during the early Eocene. It contains a single species, E. veronensis from the Monte Bolca site of Italy.
Eocottus was a small fish that superficially resembled a goby or sculpin. It was initially described in Gobius by Giovanni [Serafino Volta|Volta] , and moved to its own genus Eocottus by Arthur [Smith Woodward|Woodward], who considered it to be a relative of sculpins, hence its new name. However, Bannikov determined it to be not closely related to any modern percomorph group, and placed it in its own family Eocottidae alongside Bassanichthys. Eocottidae may potentially belong to the Perciformes, although this is uncertain.
