A novel specimen-based mid-Paleozoic dataset of antiarch placoderms (the most basal jawed vertebrates)

Earth System Science Data, 2023
Abstract. Antiarcha data are essential to quantitative studies of basal jawed vertebrates. The absence of structured data on key groups of early vertebrates, such as Antiarcha, has lagged in understanding their diversity and distribution patterns. Previous works of early vertebrates usually focused on anatomy and phylogeny, given their significant ...

Late Devonian antiarch remains (placoderm fish) from the Gilberton Formation, north Queensland

Memoirs of the Queensland Museum - Nature, 2020
New Devonian fish remains are described from the lower part of the Gilberton Formation of north Queensland, the first identifiable specimens found since the original specimen was described in 1936. They include the first determinable dermal skull bones from this deposit.

The Sinolepidae, a family of antiarchs (placoderm fishes) from the Devonian of South China and eastern Australia

Records of the Australian Museum, 1992
Two new antiarchs are described, from the Late Devonian Hunter Siltstone near Grenfell in south-eastern Australia (Grenfellaspis branagani n.gen., n.sp.), and from the Early Middle Devonian Dayaoshan Group in Guangxi, south-eastern China (Dayaoshania youngi n.gen., n.sp.). New material is described of Xichonolepis qujingensis P'an & Wang, 1978 from the
