Jaws from the jawless Until a fossil called Entelognathus was found to contain tripartite jaw few years ago, it believed that skeletons of early osteichthyans (bony fish), ancestors all vertebrates, were derived independently those earlier placoderms (so-called fish). Zhu et al. now describe second Silurian placoderm more securely bridges toothlike plates development jawed condition ultimately led three-boned in modern vertebrates (see Perspective by Long). This finding upends traditional...
Since Edwin Halls groundbreaking discovery of the Hall effect in 1879, magnetism, spin, and quantization have been expanding scope effects, continuously driving transformative progress science technology. Among them, latest nonlinear (NLHE), where longitudinal electric field tunes quantum geometry to generate voltage, attracts wide attention as a sensitive probe topological phases across range materials. Here, we report new member: magnetic (MNLHE), characterized by quadratic conductivity...
Exutaspis megista Y.-H. Liu and Wang Citation1981, discovered in the Lower Devonian Jiucheng Formation of Yunnan Province, south-western China, has been under phylogenetic contention since it was first described. Initially placed within Phlyctaeniidae, later suggested to be a member Brachythoraci. Here, we re-examine morphology detail, including visceral surface skull roof dorsal aspect neurocranium, using holotype an additional specimen. Our redescription shows that possesses characters...
Abstract An apparent absence of Silurian fishes more than half-a-metre in length has been viewed as evidence that gnathostomes were restricted size and diversity prior to the Devonian. Here we describe largest pre-Devonian vertebrate ( Megamastax amblyodus gen. et sp. nov.), a predatory marine osteichthyan from Kuanti Formation (late Ludlow, ~423 million years ago) Yunnan, China, with an estimated about 1 meter. The unusual dentition new form suggests durophagous diet which, combined its...
A 409-million-year-old predatory fish provides unique insights into the early evolution of modern lobe-finned fishes.

ISSN 0311-5518.Wufengshania magniforaminis, a genus and species Euantiarcha (Placodermi: Antiarcha), is described late southwestern The referred specimens were three-dimensionally preserved in black shales, allowing high-resolution computed tomography reconstruction anatomical details. euantiarch characterized by large orbital fenestra, an...
Yinosteus major is a heterostiid arthrodire (Placodermi) from the Lower Devonian Jiucheng Formation of Yunnan Province, south-western China. A detailed redescription this taxon reveals morphology neurocranium and visceral side skull roof. shows typical characters such as anterodorsally positioned small orbits rod-like anterior lateral plates. Its resembles those advanced eubrachythoracids rather than basal brachythoracids, provides new morphological aspects in heterostiids. Phylogenetic...
Kiangyousteus yohii Liu, 1955, is a eubrachythoracid arthrodire fish (Placodermi) from the Middle Devonian Guanwu Formation of south-western China. Although was first described in China, its phylogenetic position within Eubrachythoraci remained uncertain because lack diagnostic data previous studies. A detailed redescription this taxon reveals similarities to Dunkleosteus terrelli possession transverse articular facets on parasphenoid and adsymphyseal denticles anterior supragnathal. Our...
Silurolepis platydorsalis , a Silurian jawed vertebrate originally identified as an antiarch, is here redescribed maxillate placoderm close to Qilinyu and anteroposteriorly reversed opposed the original description. The cuboid trunk shield possesses three longitudinal cristae, obstanic grooves on median dorsal plates, all uniquely shared with . Further preparation reveals morphology of dermal neck joint, slot-shaped articular fossae similar antiarchs. However, new tomographic data reveal...
Major groups of jawed vertebrates exhibit contrasting conditions dermal plates and scales. But the transition between these remains unclear due to rare information on taxa occupying key phylogenetic positions. The 425-million-year-old fish Entelognathus combines an unusual mosaic characters typically associated with stem gnathostomes or crown gnathostomes. However, only anterior part exoskeleton was previously known for this very crownward member gnathostome stem. Here, we report a...
Southern Guangxi Province is one of the important areas for study Silurian/Devonian boundary (SDB) in South China.Despite attempts to define exact level SDB Yulin (Guangxi Province) area using biostratigraphy, no consensus has been reached as indicator fossils (e.g.graptolite Monograptus uniformis uniformis, conodont Icriodus woschmidti and trilobite Warburgella rugulosa rugosa) are not coexistent China.Since Mann et al. (2001: Dynamics sequence: sedimentary cycles vs. organic matter...
