Aspidichthys

''Aspidichthys'' ("Shield fish") is a genus of large, distinctively tuberculated arthrodire placoderm of uncertain affinities from Upper Devonian marine strata in the Eastern United States and Europe.
==Anatomy==
The dermal surfaces of the thick bones are decorated with an irregular arrangement of large, rounded tubercles. Some specimens may display patterns of "imperfectly concentric rows."〔 The long median dorsal plate is subrectangular in shape, and is gently bent along the midline, which tends to have a corresponding low ridge, and a posteriorly placed carinal process on the dorsal surface.〔 In 1938, Schmidt made a restoration of ''A. ingens'' as a large-bodied, small-headed arthrodire with tremendous orbits after the now-lost holotype of that species.
