The first 2 b.y. of Earth’s history was an important time for life when microbes evolved and diversified into essentially all of the metabolic forms that now exist. Because of feedbacks between biology and the surface environment, understanding Earth’s biological history can help us understand the evolution of Earth itself. The morphological and geochemical evidence for this ancient biological history is sparse but is increasing. Here we report evidence for 2.52 Ga exceptionally large, organic…

Cryptic terrestrial fungus-like fossils of the early Ediacaran Period

The colonization of land by fungi had a significant impact on the terrestrial ecosystem and biogeochemical cycles on Earth surface systems. Although fungi may have diverged ~1500–900 million years

Structural and chemical heterogeneity of Proterozoic organic microfossils of the ca. 1 Ga old Angmaat Formation, Baffin Island, Canada

A detailed Raman spectroscopy-based study of a complex organic microfossil assemblage in the ca.

The Taphonomy of Proterozoic Microbial Mats and Implications for Early Diagenetic Silicification

The complex nature of growth and decomposition in microbial mats results in a broad range of microbial preservation. Such taphonomic variability complicates both the description of microbial elements

Stromatolites below the photic zone in the northern Arabian Sea formed by calcifying chemotrophic microbial mats

Chemosynthesis increases alkalinity and facilitates stromatolite growth at methane seeps in 731 m water depth within the oxygen minimum zone (OMZ) in the northern Arabian Sea. Microbial fabrics,

Preservation of carbon isotopes in kerogen from thermally altered Mesoproterozoic lacustrine microbialites

Stable carbon isotope geochemistry is a well-established and reliable tool for studying metabolisms of microbial communities in the Precambrian record; however, the isotopic effects of

Snapshot of an early Paleoproterozoic ecosystem: Two diverse microfossil communities from the Turee Creek Group, Western Australia

The Turee Creek Group microfossil assemblage creates a substantial reference point in the sparse fossil record of the earliest Paleoproterozoic and demonstrates that microbial life diversified quite rapidly after the end of the Archean.

A southern African perspective on the co-evolution of early life and environments

The Kaapvaal and Zimbabwe cratons host some of the earliest evidence for life. When compared to the contemporaneous East Pilbara craton, cherts and other metasedimentary horizons in southern Africa



Sulfur-cycling fossil bacteria from the 1.8-Ga Duck Creek Formation provide promising evidence of evolution's null hypothesis

Permineralized in cherts formed during and soon after the 2.4- to 2.2-Ga “Great Oxidation Event,” two biotas may evidence an opportunistic response to the mid-Precambrian increase of environmental oxygen that resulted in increased production of metabolically useable sulfate and nitrate.

Organic-walled microfossils in 3.2-billion-year-old shallow-marine siliciclastic deposits

These are the oldest and largest Archaean organic-walled spheroidal microfossils reported so far and suggest that relatively large microorganisms cohabited with earlier reported benthic microbial mats in the photic zone of marginal marine siliciclastic environments 3.2 billion years ago.

Filamentous sulfur bacteria preserved in modern and ancient phosphatic sediments: implications for the role of oxygen and bacteria in phosphogenesis

It is suggested that sulfur bacteria, which are known to mediate the precipitation of apatite in modern sediments, were also present in certain phosphogenic settings for at least the last 600 million years.

Novel vacuolate sulfur bacteria from the Gulf of Mexico reproduce by reductive division in three dimensions.

In sediment cores maintained at 4 degrees C, which undoubtedly experienced a diminishing flux of hydrogen sulfide over time, the Thiomargarita-like bacterium remained viable for up to 2 years, and each cell appeared to undergo one to three reductive divisions, perhaps as a dispersal strategy in the face of diminished availability of its putative electron donor.

Biogeochemical signatures through time as inferred from whole microbial genomes

Geochemi- cal signatures and phylogenetic relationships of prokaryotes from whole genome sequences are deduced and this link is used to infer geochemical aspects of the biosphere through time.

The cycling and redox state of nitrogen in the Archaean ocean

Organisms that produce oxygen through photosynthesis existed during the late Archaean eon, about 2,500 million years ago, but controversial evidence suggests that they may have evolved several

Dense populations of a giant sulfur bacterium in Namibian shelf sediments.

A previously unknown giant sulfur bacterium is abundant in sediments underlying the oxygen minimum zone of the Benguela Current upwelling system, and is closely related to the marine filamentous sulfur bacteria Thioploca, abundant in the up welling area off Chile and Peru.

Phylogenetic and morphologic complexity of giant sulphur bacteria

A summary of the efforts made and achievements accomplished in the past years of the large sulphur bacteria is presented, and perspectives for investigating the heterogeneity and possible evolutionary developments in this extraordinary group of bacteria are given.

Microfossil recognition in Archean rocks : an appraisal of spheroids and filaments from a 3500 M.Y. old chert-barite unit at North Pole, Western Australia

Except in exceptional circumstances, real Archean microfossils should occur in thin sections of low-grade rocks of sedimentary origin, consist of kerogen, exceed the minimum size for independently
