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

ON A RECONSTRUCTION OF THE OLFACTORY SYSTEM AND BRAIN IN ANTIARCHS (PISCES: PLACODERMI)

The Life of the Earth
The position of the nasal sacs and nostrils, as well as some features of the brain structure in antiarchs (placoderm fishes) are analyzed, based mainly on the examples of Bothriolepis and Asterolepis. A new possible reconstruction of the olfactory system and brain in antiarchs is proposed.

New information on the morphology of yunnanolepid antiarchs (Placoderm fishes) from the Early Devonian of South China

Journal of Vertebrate Paleontology, 1996
ABSTRACT Skull morphology is described from acid-prepared articulated specimens of the antiarch Phymolepis cuifenshanensis from the Early Devonian of Yunnan Province, South China. The nasal and circum-orbital bones have a similar structure to the advanced antiarch Bothriolepis, but with the nasal openings bounded laterally by the sclerotic ring ...

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

Alcheringa, 1984
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

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 ...

Devonian Antiarch Biostratigraphy of China

Geological Magazine, 1981
SummaryDevonian Antiarchi in China are chiefly distributed in the S and W of the country. They are represented by 17 genera and more than 26 species, of which three genera are cosmopolitan, namely Asterolepis, Bothriolepis and Remigolepis. The early Devonian Antiarchi fauna, Yunnanolepis, Phymolepis, Zhanjilepis, is an East Asiatic fauna.
