Further consideration of the phylogeny and classification of the order Arthrodira (Pisces: Placodermi)

Journal of Vertebrate Paleontology, 1984
ABSTRACT Evaluation of the characters used to determine the phylogeny and classification of arthrodires leads to the following conclusions: Actinolepidae are defined only by characters primitive for the order. Holonematidae are not brachythoracans but are related to Phlyctaeniidae.

First Perigondwanan record of actinolepids (Vertebrata: Placodermi: Arthrodira) from the Lochkovian (Early Devonian) of Spain and its palaeobiogeographic significance

Palaeogeography, Palaeoclimatology, Palaeoecology, 2011
Different palaeogeographic models have been proposed for the position of Laurussia ( including Baltica) and Gondwana-derived microcontinents ( including Ibero-Armorica) during Ordovician to Late Carboniferous times. Principal differences concern the presence and duration of a large ocean, the Rheic Ocean, acting as a faunal barrier between these areas.

A new Wuttagoonaspid (Placodermi, Arthrodira) from the Lower Devonian of Yunnan (South China): origin, dispersal, and paleobiogeographic significance

Journal of Vertebrate Paleontology, 2008
ABSTRACT Wuttagoonaspida is a very peculiar group of Arthrodira, hitherto known only in the Early-Middle Devonian deposits of Australia. The new genus and species Yiminaspis shenme described here is known from an incomplete skull roof from the Pragian of Zhaotong (Yunnan, South China). Despite sharing some features with the Petalichthyida (e.g.

A new antarctaspid (Placodermi, Arthrodira) from the Lower Devonian of Yunnan, China

Journal of Vertebrate Paleontology
Antarctaspids, a basal subgroup within the Arthrodira, display a mosaic of arthrodire and petalichthyid features. However, their morphology has remained poorly understood due to the paucity of well-preserved specimens. Here, we describe a new antarctaspid arthrodire, Panjiangosteus eurycephala gen. et sp.

A Redescription ofEldenosteus arizonensis(Placodermi: Arthrodira) from the Upper Devonian Martin Formation of Northern Arizona

Journal of Vertebrate Paleontology, 1995
ABSTRACT New material of Eldenosteus arizonensis from the Upper Devonian Martin Formation of Mt. Elden, northern Arizona allows a more complete description of the body armor and the hitherto unknown skull. The new reconstruction verifies the position of Eldenosteus as a coccosteomorph arthrodire, and shows its affinity with the Torosteidae ...
