Description
Compagopiscis is one of the earliest known vertebrates to have teeth.[3] An analysis of its bite force suggests that it was a generalist predator, having a diverse diet.[4] Fossils have been found in numbers, suggesting possible schooling behavior.[4]

Perspective
Compagopiscis was originally classified as a member of the family Plourdosteidae.[5] However, phylogenetic analysis later found Plourdosteidae to be an invalid grouping, and the family was dismissed.[6] Torosteus is now considered to be a member of the superfamily Incisoscutoidea, which belongs to the clade Coccosteomorphi, one of the two major clades within Eubrachythoraci.
