Cambrian lobopodians are important for understanding the evolution of arthropods, but despite their soft-bodied preservation, organization cephalic region remains obscure. Here we describe new material early lobopodian Onychodictyon ferox from southern China, which reveals hitherto unknown head structures. These include a proboscis with terminal mouth, an anterior arcuate sclerite, pair ocellus-like eyes and branched, antenniform appendages associated this ocular segment. findings, combined...
Significance New material from the Chengjiang fossil Lagerstätte clarifies identity of three early Cambrian problematica. The presumed earliest hemichordate Galeaplumosus abilus and putative ancient sea pen Chengjiangopenna wangii are in fact fragments Xianguangia sinica . Here we demonstrate that X. possessed a polypoid body, blind gastric cavity partitioned by septum-like structures, holdfast contained an additional functioning as hydroskeleton, basal pit used for anchorage, radial whorl...
Although fossil evidence suggests that various animal groups were able to move actively through their environment in the early stages of evolution, virtually no direct information is available on nature muscle systems. The origin jellyfish swimming, for example, great interest biologists. Exceptionally preserved muscles are described here benthic peridermal olivooid medusozoans from basal Cambrian China (Kuanchuanpu Formation, ca. 535 Ma) have equivalent modern medusozoans. They consist...
Abstract Background Vetulicolians are a group of Cambrian metazoans whose distinctive bodyplan continues to present major phylogenetic challenge. Thus, we see vetulicolians assigned groups as disparate deuterostomes and ecdysozoans. This divergence opinions revolves around strikingly arthropod-like body, but one that also bears complex lateral structures on its anterior section interpreted pharyngeal openings. Establishing the homology these is central resolving where sit in metazoan...
Ctenophores are traditionally regarded as "lower" metazoans, sharing with cnidarians a diploblastic grade of organization. Unlike cnidarians, where skeletonization (biomineralization and sclerotization) evolved repeatedly among ecologically important taxa (for example, scleractinians octocorals), living ctenophores characteristically soft-bodied animals. We report six sclerotized armored from the early Cambrian period. They have diagnostic ctenophore features an octamerous symmetry,...
We herein report a fossilized polychaete annelid, Guanshanchaeta felicia gen. et sp. nov., from the Lower Cambrian Guanshan Biota (Cambrian Series 2, stage 4). The new taxon has generalized morphology, with biramous parapodia (most of which preserve evidence chaetae), an inferred prostomium bearing pair appendages, and bifid pygidium. G. is first unequivocal annelid reported China. It represents one oldest annelids among those other early Paleozoic Lagerstätten including Sirius Passet...
Abstract We describe here Sinaster petalon gen. et sp. nov., a new embryonic form from the c . 535 million‐year‐old Kuanchuanpu Formation of South China (Ningqiang, Shaanxi Province). The excellent three‐dimensional, phosphatic preservation these microfossils allowed us to use x‐ray microtomographic techniques make accurate reconstructions their internal structures and compare anatomy point‐by‐point with that extant cnidarians other animal groups. has anatomical features typical Medusozoa...
Trade-offs play a crucial role in the evolution of life-history strategies extant organisms by shaping traits such as growth pattern, reproductive investment, and lifespan. One important trade-off is between offspring number energy (nutrition, parental care, etc.) allocated to individual offspring. Exceptional Cambrian fossils allowed us trace earliest evidence trade-offs arthropod reproduction. †Chuandianella ovata, from early Chengjiang biota China, brooded numerous (≤100 per clutch),...
Abstract: Apart from previously reported Small Shelly Fossils (SSFs), a macroscopic fossil assemblage, comprising abundant algae, cone‐shaped tubular forms, and probable impressions of megascopic metazoan, comes the Lower Cambrian Yanjiahe Formation in Yangtze Gorges area western Hubei Province, south China. The visible fossils are preserved thinlaminated siltstone or muddy intercalated between 8–15 mm‐thick carbonate deposits, probably representing sedimentary settings constrained local...
Lobopodians, which diversified and flourished in the Cambrian seas, have long drawn much attention that not only their extant close relatives, onychophorans tardigrades, but euarthropods (Chelicerata, Myriapoda, Crustacea, Hexapoda) may been deeply rooted stem-group lobopodians. Antennacanthopodia gracilis new genus species is described interpreted here as an “unarmoured” lobopodian from Chengjiang fossil Lagerstätte (Early Cambrian, —520 Ma), Yunnan, southwestern China. This animal shares...
Background Non-alcoholic fatty liver disease (NAFLD) caused by lipid dysregulation is linked to obesity. Somatostatin (SST) and its analogs have been used treat pediatric hypothalamic However, the application of such drugs for treatment NAFLD has not evaluated. Objective This study aimed investigate expression levels important regulators hepatic metabolism possible effect SST analog octreotide on these regulators. Methods SD rats were assigned a control group high-fat diet group. Obese from...
Abstract The tetraradial or pentaradial fossil embryos and related hatched individuals from the early Cambrian Kuanchuanpu Formation are of great interest for understanding evolution medusozoans. phylogenetic evolutionary significance their external internal characters (e.g. manubrium, tentacles, septa claustra) is still controversial. Here we describe a new pentamerous medusozoan, Hanagyroia orientalis gen. et sp. nov., characterized by five well‐developed perradial oral lips around...
Abstract The early Cambrian pentamerous microfossil Olivooides/Punctatus in South China, which is characterized by a diagnostic stellate tubular apex, has been well‐known for its almost complete development sequence that can be confidently traced from embryos and hatched juveniles, to conical adults. However, zoological affinity remains highly controversial. Here we describe the internal microanatomic structures of soft‐body inside peridermal theca Olivooides multisulcatus Qian, 1977,...
Reduced hepatic glycogenesis is one of the most important causes metabolic abnormalities in non‑alcoholic fatty liver disease. Octreotide, a somatostatin analogue, has been demonstrated to promote weight loss and improve disorders mice with high fat diet (HFD)‑induced obesity. However, whether octreotide affects unknown. The aim present study was verify effects on rats HFD‑induced Male Sprague‑Dawley were fed standard or HFD for 24 weeks. Obese from group further divided into HFD‑control an...
