I present information on the morphology of the braincase of Ptomacanthus, which is certainly more than 100 million years more than Acanthodes. It really is a different morphology from Acanthodes radically, which has several important implications for the human relationships of acanthodians. The braincase of Acanthodes seems to most carefully resemble that of early bony vertebrates, the lineage that eventually includes humans and other land-living vertebrates). For this reason, the acanthodians were thought to share a closer ancestor with bony vertebrates than with sharks. Nevertheless, the braincase of Ptomacanthus more carefully resembles that of early shark-like fishes, and shares hardly any features in keeping with Acanthodes and the bony vertebrates.
