Large Language Models (LLMs) as chatbots have drawn remarkable attention thanks to their versatile capability in natural language processing well a wide range of tasks. While there has been great enthusiasm towards adopting such foundational model-based artificial intelligence tools all sectors possible, the capabilities and limitations LLMs improving operation electric energy sector need be explored, this article identifies fruitful directions regard. Key future research include data...
Ediacara fossils [575 to 542 million years ago (Ma)] represent Earth's oldest known complex macroscopic life forms, but their morphological history is poorly understood. A comprehensive quantitative analysis of these indicates that the assemblage-the Avalon assemblage (575 565 Ma)-already encompassed full range morphospace. comparable morphospace was occupied by subsequent White Sea (560 550 Ma) and Nama (550 assemblages, although it populated differently. In contrast, taxonomic richness...
Upper Neoproterozoic successions in the North China and nearby Chaidam blocks are poorly documented. typically consist of a diamictite unit overlain by siltstone, sandstone, or slate. Similar occur Chaidam, although cap carbonate lies atop unit. The diamictites both have been variously interpreted as Cryogenian, Ediacaran, Cambrian glacial deposits. In this paper, we describe problematic macrofossils collected from slate upper Zhengmuguan Formation sandstone Zhoujieshan Chaidam;...
The basal Cambrian marks the beginning of an important chapter in history life. However, most paleontological work on has been focused skeletal animal fossils, and our knowledge about primary producers—cyanobacteria eukaryotic phytoplankton (e.g., acritarchs)—is limited. In this research, we have investigated acritarchs, coccoidal microfossils, cyanobacteria preserved phosphorites cherts Yanjiahe Formation Yangtze Gorges area (South China) Yurtus Aksu (Tarim Block, northwestern China). Our...
Sedimentary strata of the terminal Ediacaran (635–542 Ma) to early Cambrian (542–488 Laobao-Liuchapo bedded cherts in South China Block include Oxidation Event and explosion. Understanding origin depositional environment may provide insight into how Earth's surface changed between Proterozoic Phanerozoic. We measured major trace element compositions Ge/Si ratios Laobao from northern Guangxi province. The were deposited deep basinal Block. show that composition is determined by a mixture four...
Horodyskia is one of the earliest known macroscopic life forms, with a fossil record dating from c . 1.4 Ga. Palaeopascichnus represents key Ediacaran element world-wide distribution. However, their body constructions and affinities are poorly understood, partly because previously described species mostly preserved as casts moulds in siliciclastic rocks. Silicified specimens upper Liuchapo Formation eastern Guizhou, South China, minor sp. nov. jiumenensis Their taxonomic assignments based on...
The earliest unambiguous evidence for animals is represented by various trace fossils in the latest Ediacaran Period (550-541 Ma), suggesting that lived on or even penetrated into seafloor. Yet, O2 fugacity at sediment-water interface (SWI) animal proliferation poorly defined. preferential colonization of seafloor as a first step evolution also unusual. In order to understand environmental background, we employed new proxy, carbonate associated ferrous iron (Fecarb), quantify oxygenation....
Abstract Euxinia, a crucial geological condition, usually signifies more severe extinction events attributed to deoxygenation in Earth's history. Despite extensive exploration of various proxies paleoredox studies, most are primarily utilized reconstruct atmospheric p O 2 , the proportion anoxic water relative entire basin, and broader trends redox states. Few, however, hold capacity precisely delineate local euxinia within confined areas. To address this gap gain insights into temporal...
Beijing CBD area project involves the evaluation of roadway network. Due to importance this and its special geographical location, it is necessary analyze traffic influence in future years. VISSIM a microscopic simulation software which has been widely used assessing conditions. It especially useful evaluate different management scenarios choose best alternative optimization measures before implementation. This paper builds road network model VISSIM. Four organization plans are compared....
Abstract Molar tooth structures are ptygmatically folded and microspar-filled common in early- mid-Proterozoic (∼2,500–750 million years ago, Ma) subtidal successions, but extremely rare rocks <750 Ma. Here, on the basis of Mg S isotopes, we show that molar may have formed within sediments where microbial sulphate reduction methanogenesis converged. The convergence was driven by abundant production methyl sulphides (dimethyl sulphide methanethiol) euxinic or H 2 S-rich seawaters were...

Abstract Non-biomineralizing Ediacaran macrofossils are rare in carbonate facies, but they offer valuable information about their three-dimensional internal anatomy and can broaden our view taphonomy palaeoecology. In this study, we report a new fossil, Curviacus ediacaranus genus species, from bituminous limestone of the Shibantan Member Dengying Formation Yangtze Gorges area South China. is reconstructed as benthic modular organism consisting serially arranged crescent-shaped chambers.
