Golshanichthys is an extinct monospecific genus of dunkleosteid from the Late Devonian: Frasnian stage from Kerman, Iran.

Phylogeny

Golshanichthys belongs to the family Dunkleosteidae, closely related to the giant Dunkleosteus.[1][2] The phylogeny of Golshanichthys can be shown in the cladogram below:[2]

Dunkleosteoidea

Westralichthys uwagedensis

Protitanichthys rockportensis

Panxiosteidae

Panxiosteus ocullus

Janiosteus timanicus

Plourdosteus canadensis

Dunkleosteidae

Eastmanosteus calliaspis

Xiangshuiosteus wui

Eastmanosteus pustulosus

Kiangyousteus yohii

Golshanichthys asiatica

Dunkleosteus amblyodoratus

Dunkleosteus terrelli

Dunkleosteus raveri

Alternatively, the subsequent 2016 Zhu et al. study using a larger morphological dataset recovered Panxiosteidae well outside of Dunkleosteoidea, leaving the status of Dunkleosteidae as a clade grouping separate from Dunkleosteoidea in doubt, as shown in the cladogram below:[3]

Dunkleosteoidea

Eastmanosteus calliaspis

Eastmanosteus pustulosus

Kiangyousteus yohii

Golshanichthys asiatica

Westralichthys uwagedensis

Dunkleosteus raveri

Dunkleosteus terrelli

Dunkleosteus amblyodoratus

Heterostiidae

Heterosteus ingens

Yinosteus major
