Genera

Coccosteidae is a family of arthrodire placoderms from the Early to Late Devonian. Fossils appear in various strata in Europe, North America and China.

Genera[edit]

Belgiosteus[edit]

A genus of very large coccosteids. Species are found in Middle Devonian Belgium and China.

Clarkosteus[edit]

Coccosteus[edit]

The type genus of the family. Numerous species are found in Middle to Upper Devonian strata throughout Europe and parts of North America.

Dickosteus[edit]

Jiuchengia[edit]

The earliest known coccosteid from Late Emsian Yunnan, 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.

Protitanichthys[edit]

A genus of moderately large coccosteids from Eifelian Ohio and Early Givetian Michigan of Eastern United States. Protitanichthys is distinguished from other coccosteid genera by a pattern of large tubercles. The generic name refers to how it was originally described as a progenitor genus to the Late Devonian Titanichthys. Although now determined to be only distantly related to Titanichthys, Protitanichthys shares some features with the plourdeosteids.

Watsonosteus[edit]

Woodwardosteus[edit]
