Synauchenia coalescens is unique among arthrodires in that the head shield and the trunk shield are fused or "firmly sutured" together in an immobile, helmet-like unit.[1] The neck gap is absent, and the articulations between the cranium and thorax are lost in the evolution of this peculiar feature.[1] The skull of the holotype is 10 cm long.
Synauchenia coalescens was originally placed in its own family, but, it was later determined to be closely related to Oxyosteus and Brachydeirus, and accordingly placed within Brachydeiridae.
