Synchrotron radiation (SR) is an electromagnetic radiation produced when electrons are
forced to assume a curved trajectory resulting in an emission of a bright beam of high energy …

The biogenicity problem of geological materials is one of the most challenging ones in the
field of paleo and astrobiology. As one goes deeper in time, the traces of life become feeble …

The Crato Formation (Lower Cretaceous, Brazil) is a Konservat-Lagerstätte preserving a
great number of exceptionally well-preserved insects. Here, we sought to explore the …

Studying exceptionally well-preserved biotas can bring significant answers to the
relationship between micro-organisms, biosignatures, and preservational processes. Among …

Abstract The Aptian–Albian Amargosa Bed, Tucano Basin, which was recently considered
as a Konservat-Lagerstätten, is a relatively thin, siliciclastic-dominated succession of …

The fossil-diagenetic characteristics, such as mineralogical aspects present in the ribs of
Catonyx cuvieri (Lund, 1839)(Mammalia, Xenarthra), were analyzed in this work. These …

Minerals are the fundamental record of abiotic processes over time, while biominerals are
one of the most common records of life due to their easy preservation and abundance …

Microbial activity can be expressed in a wide range of products and forms including boring
structures, biofilm-like subproducts, and framboidal pyrite precipitates. Microendolithic …

The microbial endoliths study from the Western Carpathians region was a semi-quantitative
survey that included six sampling localities. Samples, ranging from Upper Oligocene to …

Neste trabalho, combinamos um conjunto de técnicas, como espectroscopia Raman,
difração de raios-X (DRX), espectroscopia infravermelho por transformada de Fourier …
