Brachythoraci is an extinct suborder of arthrodire placoderms, armored fish most diverse during the Devonian.
Phylogeny
Arthrodira is divided into three main groups: the paraphyletic Actinolepida and Phlyctaenii, and then the monophyletic Brachythoraci. Brachythoraci is then further divided into the large derived clade Eubrachythoraci and several basal groups: Buchanosteoidea, Homosteidae, and Holonematidae.[1] (Although Holonematidae's membership in Brachythoraci is disputed.)[2]
