Kiangyousteus is an extinct monotypic genus of dunkleosteid from the Middle Devonian: Givetian aged Guanwu Formation in the Sichuan province of south-western China. The type species, Kiangyousteus yohii, was the first known arthrodire from Asia. [1]
Kiangyousteus is named after Jiangyou (formerly ‘Kiangyou’) district of Sichuan Province, the location where the fossils were found in 1953 by Professor S. H. Yoh of Peking University. [1]
Kiangyousteus belongs to the family Dunkleosteidae. The phylogeny of Kiangyousteus can be shown in the cladogram below: [1]
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: [2]
