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 ...

Devonian antiarchs (Pisces, Antiarchi) from central and Southern European Russia

Paleontological Journal, 2008
Antiarchi (Pisces, Placodermi) from the Devonian of central and southern European Russia (Central Devonian Field) are studied. Antiarchs belong to three families, the Asterolepididae, Remigolepididae (suborder Asterolepidoidei), and Bothriolepididae (suborder Bothriolepidoidei). The diagnoses of the order, two suborders, three families, and five genera

Ontogenetic development of antiarch dermal ossifications

Geobios, 1995
Abstract The histological structure of the dermal ossifications of juvenile and adult Asterolepis (Placodermi, Antiarchi) isdescribed. Six development stages of the dermal ossifications are described in living soft-shelled turtle (Trionyx). An attempt of reconstruction of the dermal plates and scales development in Asterolepis is made using a ...

Bothriolepiform antiarchs (Pisces, Placodermi) from the devonian of Central Kazakhstan

Paleontological Journal, 2011
Bothriolepiform antiarchs (Placodermi, Antiarchi) are represented by two genera in the Devonian of Central Kazakhstan: Bothriolepis Eichwald (Bothriolepididae) and Tenizolepis Malinovskaja (Dianolepididae). The first includes five species: B. babichevi Malinovskaja, 1992, B. kassini Malinovskaja, 1988, B. amankonyrica Malinovskaja, 1988, B.
