Although it is not known when or where life on Earth began, some of the earliest habitable environments may have been submarine-hydrothermal vents. Here we describe putative fossilized microorganisms that are at least 3,770 million and possibly 4,280 million years old in ferruginous sedimentary rocks, interpreted as seafloor-hydrothermal vent-related precipitates, from the Nuvvuagittuq belt in Quebec, Canada. These structures occur as micrometre-scale haematite tubes and filaments with… Expand
The history of life at hydrothermal vents
Abstract Hydrothermal vents are among the most fascinating environments that exist within the modern oceans, being home to highly productive communities of specially-adapted fauna, supported byExpand
Did Life Begin Soon After the Earth Formed?
There are no confirmed microfossils older than 3,500 million years (Myr) on Earth. Recently Mathew Dodd, Dominic Papineau, Tor Grenne, John Slack, Martin Rittner, Franco Pirajno, Jonathan O’Neil, andExpand
Widespread occurrences of variably crystalline 13C-depleted graphitic carbon in banded iron formations
Abstract Almost all evidence for the oldest traces of life on Earth rely on particles of graphitic carbon preserved in rocks of sedimentary protolith. Yet, the source of carbon in such ancientExpand
Biogenic and Abiogenic Graphite in Minerals and Rocks of the Early Earth
Minerals and rocks older than 3.7 billion years in age have attracted investigators looking to find evidence for traces of life. However, ancient rocks are heavily metamorphosed, leaving onlyExpand
Dubiofossils from a Mars-analogue subsurface palaeoenvironment: The limits of biogenicity criteria.
TLDR
It is argued that abiotic processes driven by serpentinization could account for the same set of lifelike features, and a chemical garden experiment is reported that supports this view. Expand
Signatures of early microbial life from the Archean (4 to 2.5 Ga) eon
Abstract The Archean era (4 to 2.5 billion years ago, Ga) yielded rocks that include the oldest conclusive traces of life as well as many controversial occurrences. Carbonaceous matter is found inExpand
Earth's earliest and deepest purported fossils may be iron-mineralized chemical gardens

TLDR
Here, it is shown experimentally that abiotic chemical gardening can mimic such purported fossils in both morphology and composition, while also producing the precursors to the iron minerals most commonly constitutive of filaments in the rock record. Expand
Microbial-tubeworm associations in a 440 million year old hydrothermal vent community
TLDR
The Yaman Kasy fossil filaments represent the oldest animal–microbial associations preserved within an ancient hydrothermal vent environment, and demonstrate that remarkable fine-scale microbial preservation can also be observed in ancient vent deposits, suggesting the possible existence of similar exceptionally preserved microfossils in even older vent environments.

On the biogenicity of Fe-oxyhydroxide filaments in silicified low-temperature hydrothermal deposits: Implications for the identification of Fe-oxidizing bacteria in the rock record.
Microaerophilic Fe(II)-oxidizing bacteria produce biomineralized twisted and branched stalks, which are promising biosignatures of microbial Fe oxidation in ancient jaspers and iron formations.Expand
Textural and geochemical characteristics of hematitic chert deposits in SW Norway: Implications for formation settings and processes
Jasper, a specific type of hematitic chert, is often interpreted as an ancient analogue to modern seafloor hydrothermal deposits. Modern lowtemperature seafloor hydrothermal Fe-deposits are mainlyExpand

Reassessing the evidence for the earliest traces of life
TLDR
It is shown that graphite occurs abundantly in secondary carbonate veins in the ISB that are formed at depth in the crust by injection of hot fluids reacting with older crustal rocks (metasomatism); these metasomatic rocks, which clearly lack biological relevance, were earlier thought to be of sedimentary origin.

It is suggested that the biogenic FeMO Deep hydrothermal deposit represents a modern analog for one class of geological iron deposits known as ‘umbers’ because of striking similarities in size, setting and internal structures. Expand

TLDR
Results indicate that microbial communities vary at the micron scale and that early and rapid silicification is paramount to long-term preservation, especially where minimal postdepositional disturbance follows fossilization. Expand
