How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

The Jurassic stratigraphic succession of the Lombardy Basin (Southern Alps) is part of the southern Tethys passive continental margin. A Late Triassic-Early Jurassic rifting phase resulted in regional bathymetric differentiation vis-à-vis deep basins and structural highs. Outcrops of Jurassic sections at Colle di Sogno remain undisturbed, and inclu...
In this study, we focus on a newly discovered Early Pleistocene archaeological site – AGS (Alberto Gómez Site) – at Olduvai Gorge in Northeast Africa to identify coeval landscape resources via a multi-proxy perspective. We explore the distribution of four major compound classes (n-alkanes, n-alcohols, n-alkanoic acids, and sterols) and leaf-wax δ13...
Outstanding questions about human evolution include systematic connections between critical landscape resources—such as water and food—and how these shaped the competitive and biodiverse environment(s) that our ancestors inhabited. Here, we report fossil n-alkyl lipid biomarkers and their associated δ13C values across a newly discovered Olduvai Gor...
Humic substances play empirically several essential functions in biogeochemical cycles such as storage of carbon, pollutants, nutrients, and water, yet the underlying mechanisms remain poorly known because their precise molecular structure is largely unknown so far. Here, we extracted humic substances from biomass waste of bell pepper, fennel, arti...
Among the outstanding questions about the emergence of human-controlled fire is the systematic recurrence between the geochemical remains of fire and its preservation in the archaeological record, as the use of fire is considered a technological landmark, especially for its importance in food cooking, defensive strategies, and heating. Here we repo...
