Microbrachiidae

Microbrachiidae is an extinct family of tiny, advanced antiarch placoderms closely related to the bothriolepidids.

Fossils of this genus are found in the Xindu Formation portion of the Late Emsian-aged Chuandong Assembly, in Pingle, Guangxi Province, China.

The armor plates are covered in rows of small tubercles, in a pattern similar to that of M. sinensis.

A genus of very small antiarchs, originally described from M. dicki, of Upper Givetian strata of Scotland and Estonia, including the John O'Groats sandstone of Caithness, and the Eday beds of the Orkney Islands.

As the generic name suggests, Wudinolepis is found in Wuding, Yunnan, China in a Late Emsian-aged stratum called the Jiucheng Formation.
