Golshanichthys Explained

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]

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]
