Coccosteidae is a family of arthrodire placoderms from the Early to Late Devonian. Fossils appear in various strata in Europe, North America and China.
Phylogeny[edit]
Coccosteidae belongs to the larger clade Coccosteomorphi, which together with its sister clade Pachyosteomorphi forms the group Eubrachythoraci. The phylogeny of Coccosteidae can be shown in the cladogram below:[1]

The earliest known coccosteid from Late Emsian Yunnan province, China. It is distinguished from other coccosteids by having an elongated occipital.
Livosteus[edit]
A genus of very large coccosteids known from Middle to Late Devonian strata of Eastern Europe.
Millerosteus[edit]
A genus of very small coccosteids known from Middle to Late Devonian strata throughout Europe. Some species are found in the same strata with certain species of Coccosteus.
