The relationships of antiarchs (Devonian placoderm fishes) - evidence supporting placoderm monophyly.
A recent analysis of the vascularization of the pectoral fin in antiarchs indicated that they resembled jawless osteostracans rather than other jawed vertebrates, thereby challenging the monophyly of the class Placodermi. Examination of the evidence proposed to support this new hypothesis shows misinterpretation of well-established morphology in a range of antiarchs, with incorrect homologies being applied to conclude that the subclavian artery and vein originated in the back of the branchial...[Show more]
