Brachydeiridae

Brachydeiridae is a family of small to moderately large-sized arthrodire placoderms from the Late Devonian of Europe, restricted primarily to the Kellwasserkalk Fauna of Bad Wildungen and Adorf.
Brachydeirids have, in cross section, a highly compressed body, a pointed, sometimes highly elongated snout, and tremendous orbits. The plates of the trunk shield are noticeably shortened: in ''Synauchenia'', the trunk shield and head shield are fused together as a single, immovable unit. The superficial anatomy of brachydeirids is extremely diverse, and each genus has been previously placed in their own monogeneric families.〔
The brachydeirids, together with ''Leptosteus'', make up the superfamily Brachydeiroidea.
