SUMMARY Morphological phylogenetic analyses suggest that scalidophorans (priapulids, loriciferans, and kinorhynchs) nematoids (nematodes nematomorphs) form the ecdysozoan clade Cycloneuralia, which is a sister group to panarthropods. It has been proposed extant priapulids Cambrian priapulid‐like scalidophorans, because of their conserved evolution, have potential illuminate ancestral morphology, ecology, developmental biology highly derived ecdysozoans such as nematods arthropods. As such,...
Morphology-based phylogenetic analyses support the monophyly of Scalidophora (Kinorhyncha, Loricifera, Priapulida) and Nematoida (Nematoda, Nematomorpha), together constituting monophyletic Cycloneuralia that is sister group Panarthropoda. Kinorhynchs are unique among living cycloneuralians in having a segmented body with repeated cuticular plates, longitudinal muscles, dorsoventral ganglia. Molecular clock estimates suggest kinorhynchs may have diverged Ediacaran Period. Remarkably, no...
Abstract Animals with radial symmetry are abundant in the Cambrian Fortunian Stage of South China, but relatively low diversity: representatives include Olivooides , Quadrapyrgites carinachitiids, hexangulaconulariids and Pseudooides . Here, we report a new animal, Qinscyphus necopinus gen. et sp. nov., from small shelly fauna southern Shaanxi Province, China. has cup‐shaped profile, slightly raised annuli five groups triangular thickenings pentaradial symmetry. This organism comparable...
Abstract Although molecular studies estimated that cycloneuralians might have originated in the Ediacaran Period and diversified early Cambrian, it was not until 2014 they were first reported from Cambrian Fortunian Stage. To date only two species five indeterminate forms been described. Here, we report new three‐dimensionally phosphatized microfossils of Zhangjiagou Lagerstätte, South China. Two genera species, Qinscolex spinosus gen. et sp. nov. Shanscolex decorus nov., Indeterminate Forms...
Archaeocyaths are biocalcified sponges largely restricted to the early Cambrian Period. Their perforated cup-shaped body facilitated filter feeding. Many of them were clonal modular animals that formed earliest metazoan skeletal reefs. In Siberia, archaeocyaths extend from late Age 2 4 Cambrian, representing an ∼15 m.y. range (ca. 525−510 Ma). Elsewhere, emerged later than in Siberia and, places, survived middle-late Cambrian. The existing fossil record thus indicates out-of-Siberia scenario...
Abstract The latest discovery of microfossils from the lower Cambrian (Fortunian Stage) Zhangjiagou Lagerstätte in South China are presented. This lagerstätte is rich exceptionally preserved microfossils, including embryos Olivooides multisulcatus , mirabilis and Pseudooides prima ; hatched stages O . Hexaconularia sichuanensis Quadrapyrgites quadratacris cycloneuralians represented by Eopriapulites sphinx largest known fragment implies that its adult length can be more than 9.0 mm with at...
Abstract Some rare microscopic cycloneuralians are present in the Cambrian of South China, represented by Eopriapulites and Eokinorhynchus (both early Cambrian), fossil embryos Markuelia (middle to late palaeoscolecids (early Cambrian). Among them, relatively diverse abundant. Here, we describe new material three-dimensionally phosphatized from Paibian Stage Wangcun Lagerstätte, western Hunan, China. New includes assignable sp., two other types embryos, three species palaeoscolecids,...
Abstract The Jehol fauna was initially represented by a bony fish, concostracan and an insect, as Lycoptera davidi–Eosestheria–Ephemeropsis trisetalis association, but since the researches of recent decades, Biota is now completely different from past low‐diversity, encompasses native terrestrial biota that includes many well‐preserved vertebrates, invertebrates plants. There are more than 20 important biological categories, thousands taphonomically unusual fossils, especially noted for wide...
Fine pyroclastic materials form bentonites through subsidence, hydrolysis, and argillation in alkaline marine environments, which can further transform to K‐bentonite. Bentonites or K‐bentonites are quite popular with geologists because their formation often reflects geologic events. However, studies mainly focus on K‐bentonite, research ordinary China is almost nonexistent. Recent shows that the Wangpo shale consists of bentonites. Through thorough field investigations, indoor...
Abstract Maikhanellids are a distinct group of Cambrian Fortunian small shelly fossils by the cap‐shaped profiles and scaly shell ornamentation. According to individual shape ornamentation feature types SO maikhanellids which were collected from Xixiang botia, we confirmed family Maikhanellidae content six genera, Maikhanella, Ramenta, Purella, Ramentoides, Yunnannopleura Mediata. Unlike halkieriid animals whose shells spicules articulated on different body parts, presumably yielded...
The Kekebieketi mining area is located on the southern margin of Altai Mountains in Northern Xinjiang and at junction Siberia Kazakhstan‐Junggar plates.

The Llandovery (lower Silurian) Liangshan Danangou section of Nanzheng, southern Shaanxi Province, China, contains a complete Aeronian succession and abundant graptolites. One hundred twenty‐five species graptolite have been found in this section. Using high‐resolution methods, the Rhuddanian, Aeronian, Telychian strata divided into 3, 4, 1 zones, respectively. In particular, there are 47 newly established Spirograptus andrewsi Zone (Aeronian) which has 2 subzones; lower Monograptus...
Microscopic medusozoans from the Cambrian Fortunian stage of South China are well known for their exceptionally preserved embryos and elongated tubes. However, additional details morphology remain unclear. This paper describes new medusozoan fossils showing whole apical complement covering morphological integrity Qinscyphus . The part is considered to be soft during early ontogeny, inverted pentagonal pyramid may gradually form with growth development. discovery novel essential external...
Abstract A wide variety of scalidophoran worms have been found in the Cambrian Fortunian recent years, suggesting that scalidophorans diversified during this age. Here, we report new material obtained from 2nd member Kuanchuanpu Formation (Fortunian Stage) Zhangjiagou Lagerstätte, Xixiang County, Shaanxi Province, South China. Three indeterminate forms are described detail. The morphology these differs any coeval and may represent taxa. However, because fossils fragmented lack detailed...
