Taemasosteus is an extinct genus of arthrodire placoderm. Its fossils have been found in Emsian-aged marine strata in the Murrumbidgee Group in New South Wales, Australia. It contains two species, T. novaustrocambricus, and T. maclartiensis.
The genus (and a monotypic family, "Taemasosteidae") was originally erected on the basis of "an imperfect" left paranuchal plate, though more specimens were found, eventually leading "Taemasosteidae" to be subsumed into Buchanosteidae.
