Vascularization of the osteostracan and antiarch (Placodermi) pectoral fin: similarities, and implications for placoderm relationships

Lethaia, 2002
Phylogenetic analyses frequently resolve the extinct group Placodermi at the base of the clade of jawed fishes (traditionally known as the Gnathostomata), with the jawless fish group Osteostraci as sister taxon to this clade. Both gnathostomes and osteostracans possess pectoral fins supported by a radial(s) articulating on a cartilaginous ...

An asterolepidoid antiarch (placoderm fish) from the Early Devonian of the Georgina Basin, central Australia

A small collection of well-preserved antiarch remains from the basal calcareous unit of the Cravens Peak Beds is described and figured. This represents the earliest record of antiarchs from the Australian continent. An Emsian age, based on correlations with the Mulga Downs Group in the Darling Basin, makes this the earliest recorded antiarch occurrence
