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]
