Microbial Fossils Found in 3.4-Billion-Year-Old Subseafloor Rock

The material, now part of an African mountain range, bolsters the idea that hydrothermal veins supported early forms of life.

3.42-Billion-Year-Old Filamentous Microfossils Found in South Africa

Paleontologists have discovered the exceptionally well-preserved, 3.42-billion-year-old filamentous microfossils in a paleo-subseafloor hydrothermal vein system in what is now South Africa; the filaments colonized the walls of conduits created by low-temperature hydrothermal fluid; combined with their ...

Buried traces hint at underground origins of life

Scientists think they have found the fossils of microorganisms that lived under the seafloor 3.5 billion years ago

Scoperti i più antichi fossili di batteri metanogeni

Analizzando le rocce presenti nel sito Unesco conosciuto con il nome di Cintura di rocce verdi di Barberton, in Sudafrica, una delle più antiche strutture geologiche al mondo, un team di ricercatori guidati da Barbara Cavalazzi dell’Università di Bologna ha scoperto i più antichi resti fossili di archeobatteri ...

3.42-Billion-Year-Old Filamentous Microfossils Found in South Africa

“We found exceptionally well-preserved evidence of fossilized microbes that appear to have flourished along the walls of cavities created by warm water from hydrothermal systems a few meters below the seafloor,” said Professor Barbara Cavalazzi, a researcher in the Dipartimento di Scienze Biologiche, ...

Oldest fossils of methane-cycling microbes expand frontiers of habitability on early Earth

A team of international researchers, led by the University of Bologna, has discovered the fossilised remains of methane-cycling microbes that lived in a hydrothermal system beneath the seafloor 3.42 billion years ago.

Ethiopia’s inhospitable Danakil Depression gives us clues about life on Mars

The Danakil Depression, including the Dallol volcanic area is one of the most remote, inhospitable and poorly studied areas in the world.

Quell'angolo di Africa che sembra Marte: lo studio dell'Ateneo di Bologna

Un gruppo di ricercatori sta studiando il cratere vulcanico del Monte Dallol, in Etiopia: "Qui potrebbero nascondersi organismi in grado di sopravvivere in ambienti simili a quelli marziani"

In Ethiopia Thinking of Mars, Searching for Life

It is in the volcanic crater of Mount Dallol, Ethiopia, that researchers from the University of Bologna go “hunting” for organisms able to survive in hostile environments similar to those of the “Red Planet”. We are 125 metres below sea level and the temperature can reach over 60 degrees, with chlorine ...
