A treasure trove of Cambrian secrets Animal life exploded in diversity and form during the period about 500 million years ago. Fu et al. describe an early fossil site China that contains a variety specimens, more than half which are previously undescribed (see Perspective by Daley). The rivals described sites, such as Burgess Shale, should help to elucidate biological innovation diversification this period. Science , issue p. 1338 ; see also 1284
The diversification of animals during the Cambrian Period is one most significant evolutionary events in Earth's history. However, sequence leading to origin 'modern' ecosystems and exact temporal relationship between Ediacaran faunas are uncertain, as identification Ediacaran–Cambrian boundary global correlation through this interval remains problematic. Here we review controversies surrounding base present new high-resolution biostratigraphic, lithostratigraphic δ13C chemostratigraphic...
Abstract Shell microstructure and mineralogy of Pelagiella madianensis Zhou & Xiao, 1984, a globally distributed Cambrian micromollusk, are investigated based on abundant extraordinarily well-preserved specimens from Xinji Formation, Longxian, Shaanxi, North China. Five types aragonitic microstructures have been recognized. The lamello-fibrillar microstructure, previously known , constructs the outermost shell layer, while remaining four reported here for first time in this genus. They...
Breast cancer patients with high expression of aldehyde dehydrogenases (ALDHs) cell population have higher tolerability to chemotherapy since the cells posses a characteristic breast stem (BCSCs) that are resistant conventional chemotherapy. In this study, we found ALDH-positive were in CD44+ CD24- and ESA+ BCSCs than both BT549 MDA-MB-231 lines but microRNA-7 (miR-7) level was lower cells. Moreover, miR-7 overexpression decreased ALDH1A3 activity by directly binding 3'-untranslated region...
Abstract Hyoliths were among the earliest biomineralizing metazoans in Palaeozoic marine environments. They have been known for two centuries and widely assigned to lophotrochozoans. However, their origin relationships with modern lophotrochozoan clades a longstanding palaeontological controversy. Here, we provide broad microstructural data from hyolith conchs opercula lower Cambrian Xinji Formation of North China, including hyolithid genera four orthothecid as well unidentified opercula....
Antimony sulfide (Sb2S3) with a high theoretical capacity is considered as promising candidate for Na-ion batteries (NIBs) and K-ion (KIBs). However, its poor electrochemical activity structural stability are the main issues to be solved. Herein, amorphous Sb2S3 nanospheres/carbon nanotube (Sb2S3/CNT) nanocomposites successfully synthesized via one step self-assembly method. In-situ growth of nanospheres on CNTs confirmed by X-ray diffraction, field-emission scanning electron microscopy,...
Abstract As extinct animals that flourished during the Cambrian explosion, chancelloriids have a unique body plan lacking guts but with flexible integument and suite of star-shaped, hollow sclerites. Due to this plan, along paucity knowledge on sclerite biomineralization, phylogenetic position within Metazoa is still controversial. Integration analyses diverse fossils from stage 2 Wuliuan Stage China Australia indicates chancelloriid sclerites possess an encasement-like organic layer fibrous...

Abstract A diverse group of molluscs from the Cambrian Series 2, Stages 3–4 Xinji Formation North China Block ( NCB ) is described, based on more than 4500 specimens three well‐studied sections in Shaanxi and Henan provinces, along southern southwestern margin . Twenty molluscan species are identified, including one bivalve, stem gastropods, 16 additional helcionelloids. Among these, six helcionelloid reported for first time, new species, Parailsanella luonanensis sp. nov. proposed. This...
Sponge fossils from the Cambrian black shales have attracted attention both palaeontologists and geochemists for many years in terms of their high diversity, beautiful preservation perplexing adaptation to inhospitable living environments. However, body shape these sponges, which contributes deciphering adaptive evolution, has not been scrutinized. New complete specimens hexactinellid sponge Sanshapentella tentoriformis sp. nov. Qingjiang biota (black shale Stage 3 Shuijingtuo Formation, ca...
Abstract Aragonitic crossed‐lamellar (CL) is one of the most commonly formed and extensively studied molluscan shell microstructures, yet its origin early evolution within Mollusca remains poorly understood. Here, a primitive CL microstructure from oldest gastropods, Pelagiella madianensis , problematic hyolith Cupitheca sp. Cambrian Series 2 Xinji Formation on North China Platform, was investigated. In P. detailed characterization has revealed typical four‐ordered hierarchical organization...
The chancelloriid Allonnia erjiensis sp. nov. is described based on articulated specimens from the Chengjiang fossil Lagerstätte (Cambrian Stage 3 of Series 2), South China. A total 16 specimens, including three complete individuals, have been recognized, all which are preserved in mudstones and highlighted by reddish iron oxides. has a conical body equipped with densely arranged 3+0-type sclerites. wall integument sclerite microstructures visible some cases. integument, ornamented...
Background and Aim: Acute myeloid leukemia (AML), initiated maintained by stem cells (LSCs), is often relapsed or refractory to therapy. The present study aimed at assessing the effects of nanozyme-like Fe 3 O 4 nanoparticles (IONPs) combined with cytosine arabinoside (Ara-C) on LSCs in vitro vivo. Methods: CD34 + CD38 – LSCs, isolated from human AML cell line KG1a a magnetic activated sorting method, were treated Ara-C, IONPs, Ara-C+ IONPs respectively vitro. cellular proliferation,...
Chancelloria australilonga sp. nov. is described from the Emu Bay Shale (Cambrian Series 2, Stage 4) of Kangaroo Island, South Australia. The new species has a typical sac-like body, equipped with meshwork dozens distinctive rosette-like sclerites. Each sclerite comprises one central ray and six or seven lateral rays, characterized by pair remarkably long subparallel adapical rays. few chancelloriid preserved an apical orifice obvious peripheral tuft. tuft consists series single-rayed...
Helens, the curved lateral spines inserted between conch and operculum of some hyoliths, are a unique morphological adaptation characterizing order Hyolithida. These structures paired, movable had mechanical function, probably related to orienting hyolith lifting its aperture above sea floor. We show that helens intimately associated with opercula structurally comparable rod like units constitute clavicles, internal wall-like hyolithid evolved secure from displacement in aperture. In early...
Hyoliths (hyolithids and orthothecids) were one of the most successful early biomineralizing lophotrochozoans a key component Cambrian evolutionary fauna. However, morphology, skeletogenesis anatomy earliest members this enigmatic clade, as well its relationship with other lophotrochozoan phyla remain contentious. Here, we present new orthothecid, Longxiantheca mira gen. et sp. nov. preserved part secondarily phosphatized small shelly fossil assemblage from lower Xinji Formation North China....
The evolutionary mechanism behind the early Cambrian animal skeletonization was a complex and multifaceted process involving environmental, ecological, biological factors. Predation pressure, oxygenation, seawater chemistry change have frequently been proposed as main drivers of this innovation, yet selection pressures from microorganisms largely overlooked. Here we present evidence that calcareous shells earliest mollusks basal (Fortunian Age, ca. 539–529 million years ago) Mongolia...

Abstract The initial acquisition of calcium carbonate polymorphs (aragonite and calcite) at the onset skeletal biomineralization by disparate metazoans across Ediacaran-Cambrian transition is thought to be directly influenced Earth's seawater chemistry. It has been presumed that animal clades first acquired mineralized skeletons during so-called “aragonite sea” latest Ediacaran earliest Cambrian (Terreneuvian) possessed aragonite or high-Mg calcite skeletons, while arose in subsequent...
