Barbara J. Stahl Further study of iniopterygian fishes from the Pennsylvanian of North America has shown that autostylic jaw suspension is not, as was originally thought, a characteristic of the group. Two of the five genera possess palatoquadrate elements that articulate with the neurocranium, a fact that calls for modification of the history of the mandibular arch tentatively proposed for these fishes.
