ABSTRACT A new Early Devonian (Lochkovian) yunnanolepiform-like antiarch Minicrania lirouyii gen. et sp. nov. is described from Qujing, Yunnan, southeastern China. This tiny antiarch possesses both a preorbital depression and a preorbital recess. It is characterized by a long and narrow skull-roof, short obstantic margin, large orbital fenestra, fairly

A new antiarch (placoderm fish) from the Early Devonian of South China
Alcheringa: An Australasian Journal of Palaeontology, 1992A new bothriolepidoid antiarch of small size, Luquanolepis pileos gen. et sp. nov. is described from the Early Devonian of Luquan County, Yunnan Province. Only remains of the trunk armour are known. It is characterised by the long dorsal wall, with a strong posterior process formed by the posterior median dorsal and posterior dorsolateral plates, the ...

AbstractAntiarch placoderm fishes were an abundant component of the Middle Paleozoic vertebrate assemblages. Despite a large number of known taxa and specimens, the morphology and function of the skeletal elements of their jaws is inadequately known.

A basal antiarch (placoderm fish) from the Silurian of Qujing, Yunnan, China
Palaeoworld, 2010Abstract A new basal antiarch, Silurolepis platydorsalis n. gen. n. sp., represented by a large-sized trunk armor and a disassociated anterior median dorsal plate (AMD), is described from the Ludlow (Silurian) of Qujing, Yunnan, southwestern China.

A new antiarch placoderm from the Emsian (Early Devonian) of Wuding, Yunnan, China
Alcheringa: An Australasian Journal of Palaeontology, 2017Wufengshania magniforaminis, a new genus and species of the Euantiarcha (Placodermi: Antiarcha), is described from the late Emsian (Early Devonian) of Wuding, Yunnan, southwestern China. The referred specimens were three-dimensionally preserved in black shales, allowing a high-resolution computed tomography reconstruction of anatomical details. The new

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 ...
