Contents
Belgiosteus
A genus of very large coccosteids. Species are found in Middle Devonian Belgium and China.
Coccosteus
The type genus of the family. Numerous species are found in Middle to Upper Devonian strata throughout Europe and parts of North America.
Jiuchengia
The earliest known coccosteid from Late Emsian Yunnan, China. It is distinguished from other coccosteids by having an elongated occipital.
Livosteus
A genus of very large coccosteids known from Middle to Late Devonian strata of Eastern Europe.
Millerosteus
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
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.
