Brachyopterus is a genus of prehistoric eurypterid of the family Rhenopteridae. It is one of the earliest known eurypterids,[1] having been recovered from Middle Ordovician deposits in Montgomeryshire, Wales.[2] Though other species have been assigned to it in the past, Brachyopterus is today recognized as containing one valid species, B. stubblefieldi.[2]
