Fossilized lipids preserved in sedimentary rocks offer singular insights into the Earth's
palaeobiology. These 'biomarkers' encode information pertaining to the oxygenation of the …

Studies of alkaline lakes have critical biological–environmental–economic properties, but
deep-time alkaline lakes are challenging to investigate. Lipid biomarkers can provide …

Eukaryotic life appears to have flourished surprisingly late in the history of our planet. This
view is based on the low diversity of diagnostic eukaryotic fossils in marine sediments of mid …

From August 2019 to June 2021, viscous oil residues appeared along the Brazilian coast
spanning 11 states and more than 3,000 km of tropical shoreline. Forensic results published …

The co-evolution of paleo-environment and bio-precursors in alkaline lakes is of significance
to understand the extreme environment system and associated enigmatic hydrocarbon …

The negative organic carbon isotope excursion (CIE) associated with the end-Triassic mass
extinction (ETE) is conventionally interpreted as the result of a massive flux of isotopically …

Fossilized carotenoid hydrocarbons provide a window into the physiology and biochemistry
of ancient microbial phototrophic communities for which only a sparse and incomplete fossil …

The reverse tricarboxylic acid (rTCA) cycle is touted as a primordial mode of carbon fixation
due to its autocatalytic propensity and oxygen intolerance. Despite this inferred antiquity …

It is established that green algae and land plants progressively colonized freshwater and
terrestrial habitats throughout the Paleozoic Era, but little is known about the ecology of …

The breakup of Gondwana resulted in sedimentary deposits recording lacustrine to marine
environmental transitions in the South Atlantic rift basins during the Early Cretaceous …
