The relationships of antiarchs (Devonian placoderm fishes)—evidence supporting placoderm monophyly

Journal of Vertebrate Paleontology, 2008
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 ...

A review of placoderm scales, and their significance in placoderm phylogeny

Journal of Vertebrate Paleontology, 1999
An historical review of the literature relating to placoderm scales preserved in association with articulated dermal plates, or as isolated units in microvertebrate assemblages, is followed by a discussion of their relevance in phylogenetic analyses of the Placodermi.

A Silurian maxillate placoderm illuminates jaw evolution

Science, 2016
Jaws from the jawless Until a fossil called Entelognathus was found to contain a tripartite jaw a few years ago, it was believed that the skeletons of early osteichthyans (bony fish), the ancestors of all vertebrates, were derived independently of those of the earlier placoderms (so-called jawless fish).
