Antiarch placoderm fishes were an abundant component of the Middle Paleozoic vertebrate assemblages. Despite a large number of known taxa and specimens, the morphology and function of the skeletal elements of their jaws is inadequately known. Because of this, questions regarding their feeding modes and their roles in the trophic webs remains open. We present a skeleto-muscular model of the antiarch jaw apparatus with an attempt to reconstruct its potential biomechanical function. The position of...
