Panxiosteidae is an extinct family of arthrodire placoderms that lived during the Devonian period.
Phylogeny
[edit ]The family Panxiosteidae was erected by Wang in 1979. Members of the family are noted for showing morphologically intermediate traits between coccosteids and dunkleosteids.[1] In the 2010 Carr & Hlavin phylogenetic study, Panxiosteidae was recognized as the sister taxon to the family Dunkleosteidae, which together comprised the superfamily Dunkleosteoidea (one of the three major clades of Eubrachythoraci).[2]
The phylogeny of Panxiosteidae from the 2013 Zhu & Zhu study is shown in the cladogram below:[3]
