Nicola Conci et al.
The formation of skeletal structures composed of different calcium carbonate polymorphs (e.g. aragonite and calcite) appears to be both biologically and environmentally regulated. Among environmental factors influencing aragonite and calcit...
Dissolved silica affects the bulk iron redox state and recrystallization of minerals generated by photoferrotrophy in a simulated Archean ocean [0.03%]
溶解硅影响模拟太古代海洋中光致铁营养菌产生的矿物的总体铁氧化还原态和重结晶过程

Chemical sedimentary deposits called Banded Iron Formations (BIFs) are one of the best surviving records of ancient marine (bio)geochemistry. Many BIF precursor sediments precipitated from ferruginous, silica-rich waters prior to the Great ...
New keratose sponges after the end-Permian extinction provide insights into biotic recoveries [0.03%]
二叠纪末大灭绝后的新的角海绵提供了对生物恢复的见解
Siqi Wu,Joachim Reitner,David A T Harper et al.
Siqi Wu et al.
We challenge the prevailing view that the end-Permian extinction impeded the Triassic evolution of sponges. Here, we report a deep-water community dominated by abundant keratose sponges in the lowest Triassic strata from Southwest China. Th...
Deep subsurface microbial life in impact-altered Late Paleozoic granitoid rocks from the Chicxulub impact crater [0.03%]
奇克苏鲁布撞击坑内晚古生代花岗质岩石中撞击改变的深部地下微生物生命

Sohaib Naseer Quraish et al.
In 2016, IODP-ICDP Expedition 364 recovered an 829-meter-long core within the peak ring of the Chicxulub impact crater (Yucatán, Mexico), allowing us to investigate the post-impact recovery of the heat-sterilized deep continental microbial...
Fossilized giant sulfide-oxidizing bacteria from the Devonian Hollard Mound seep deposit, Morocco [0.03%]
摩洛哥泥盆纪霍勒德喷口沉积物中巨大型硫化物氧化细菌化石
Daniel Smrzka,Jennifer Zwicker,Heide Schulz-Vogt et al.
Daniel Smrzka et al.
The giant sulfide-oxidizing bacteria are particularly prone to preservation in the rock record, and their fossils have been identified in ancient phosphorites, cherts, and carbonates. This study reports putative spherical fossils preserved ...
Microbial mats and their palaeoenvironmental analysis in offshore - shelf facies of the Los Molles Formation (Toarcian - Lower Callovian) in the Chacay Melehue area, Neuquén Basin, Argentina [0.03%]
阿根廷内乌肯盆地查卡伊梅莱胡埃地区洛斯莫尔斯组（下通贾尼安-卡尔洛夫阶）海台相地层中的微生物席及其古环境分析
Maximiliano Nicolás Rodriguez,Débora Mical Campetella,Noelia Beatriz Carmona et al.
Maximiliano Nicolás Rodriguez et al.
This contribution presents the first study focused on the analysis of microbial mats in the Los Molles Formation (Toarcian - Early Callovian), Neuquén Basin, Argentina. This unit mainly represents offshore-to-shelf environments affected by...
Contrasting morphology and growth habits of Frutexites in Late Devonian reef complexes of the Canning Basin, northwestern Australia [0.03%]
澳大利亚西北部康宁盆地晚泥盆世造礁复合体中Fructices形态和生长习性的差异性研究
France Champenois,Annette D George,Kenneth J McNamara et al.
France Champenois et al.
Frutexites-like microstructures are described from the exhumed Late Devonian reef complexes of the northern Canning Basin, Western Australia. Several high-resolution imaging techniques, including X-ray microcomputerised tomography, scanning...
Distinctive microfossil supports early Paleoproterozoic rise in complex cellular organisation [0.03%]
独特的微化石表明太古宙晚期复杂细胞结构的兴起
Erica V Barlow,Christopher H House,Ming-Chang Liu et al.
Erica V Barlow et al.
The great oxidation event (GOE), ~2.4 billion years ago, caused fundamental changes to the chemistry of Earth's surface environments. However, the effect of these changes on the biosphere is unknown, due to a worldwide lack of well-preserve...
Divergence time estimates for the hypoxia-inducible factor-1 alpha (HIF1α) reveal an ancient emergence of animals in low-oxygen environments [0.03%]
低氧环境中动物起源的古老性的估算：基于缺氧诱导因子1α（HIF1α）的分化时间分析
Flavia A Belato,Beatriz Mello,Christopher J Coates et al.
Flavia A Belato et al.
Unveiling the tempo and mode of animal evolution is necessary to understand the links between environmental changes and biological innovation. Although the earliest unambiguous metazoan fossils date to the late Ediacaran period, molecular c...
The role of clay minerals in the preservation of Precambrian organic-walled microfossils [0.03%]
黏土矿物在前寒武纪有机壁微体化石保存中的作用
C R Woltz,R P Anderson,N J Tosca et al.
C R Woltz et al.
Precambrian organic-walled microfossils (OWMs) are primarily preserved in mudstones and shales that are low in total organic carbon (TOC). Recent work suggests that high TOC may hinder OWM preservation, perhaps because it interferes with ch...
