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. The phylogeny of Golshanichthys can be shown in the cladogram below:

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:

Dunkleosteoidea	Eastmanosteus calliaspis         Eastmanosteus pustulosus     Kiangyousteus yohii         Golshanichthys asiatica       Westralichthys uwagedensis         Dunkleosteus raveri     Dunkleosteus terrelli         Dunkleosteus amblyodoratus   Heterostiidae   Heterosteus ingens     Yinosteus major
