A Silurian placoderm with osteichthyan-like marginal jaw bones
TLDR
A three-dimensionally preserved 419-million-year-old placoderm fish from the Silurian of China is described that represents the first stem gnathostome with dermal marginal jaw bones (premaxilla, maxilla and dentary), features previously restricted to Osteichthyes. Expand
A Silurian maxillate placoderm illuminates jaw evolution
TLDR
A second Silurian maxillate placoderm is described that more securely bridges the jawless toothlike plates of placoderms to the development of the jawed condition that ultimately led to the three-boned jaw in ancestors of modern vertebrates. Expand
A Devonian predatory fish provides insights into the early evolution of modern sarcopterygians
TLDR
The new skull material of Qingmenodus, a Pragian onychodont from China, is described using high-resolution computed tomography to image internal structures of the braincase and bridges the morphological gap between stem sarcopterygians and coelacanths and helps to illuminate the early evolution and diversification of crown sarcoperygians. Expand
The largest Silurian vertebrate and its palaeoecological implications
TLDR
The largest pre-Devonian vertebrate described is a predatory marine osteichthyan from the Silurian Kuanti Formation of Yunnan, China, with an estimated length of about 1 meter, and this finding refutes the assumption that pre-Emsian vertebrates were restricted to small body sizes. Expand
Redescription of Yinostius major (Arthrodira: Heterostiidae) from the Lower Devonian of China, and the interrelationships of Brachythoraci
TLDR
The resulting phylogenetic scenario suggests that eubrachythoracids underwent a rapid diversification during the Emsian, representing the placoderm response to the Devonian Nekton Revolution. Expand
A new petalichthyid placoderm from the Early Devonian of Yunnan, China
Abstract Pauropetalichthys magnoculus , a new genus and species within the Petalichthyida (Gnathostomata: Placodermi), is described from the Late Emsian (Early Devonian) of Qujing, Yunnan,Expand
African lungfish genome sheds light on the vertebrate water-to-land transition
TLDR
A 40-Gb chromosome-level assembly of the African lungfish genome is reported, which is the largest genome assembly ever reported and has a contig and chromosome N50 of 1.60 Mb and 2.81 Gb, respectively. Expand
First fossil record of the genus Nageia (Podocarpaceae) in south China and its phytogeographic implications
TLDR
The first fossil record of the genus Nageia Gaertner from the Tertiary of southern China is reported, indicating that this genus could have originated in the northeastern part of Asia in the Early Cretaceous and spread to south China at least in the Eocene. Expand
A redescription of Kiangyousteus yohii (Arthrodira: Eubrachythoraci) from the Middle Devonian of China, with remarks on the systematics of the Eubrachythoraci
TLDR
A detailed redescription of this taxon reveals similarities to Dunkleosteus terrelli in the possession of transverse articular facets on the parasphenoid and the lack of adsymphyseal denticles on the anterior supragnathal. Expand
