Description

Gorgonichthys had sharp, pointed edges on the dental plates of the upper and lower jaws.[1] With a headshield length of up to 70 cm (28 in),[2] it is estimated to have been comparable to the size of Dunkleosteus.[3]

Phylogeny

Summarize
Perspective

Gorgonichthys is a member of the clade Aspinothoracidi, which belongs to the clade Pachyosteomorphi, one of the two major clades within Eubrachythoraci. It is closely related to the family Selenosteidae, and could possibly be included in that family. The cladogram below shows the phylogeny of Gorgonichthys:[4]

Eubrachythoraci

According to a 2022 Jobbins et al. study, Gorgonichthys was found to be more related to Heintzichthys than Gymnotrachelus, potentially making Gorgonichthys a member of Selenosteidae.[5]
