A new anablepid (Cyprinodontiformes) from the Late Miocene of Puchuzum locality, San Juan Province, Argentina is described here. The collected specimens include male and female individuals showing marked sexual dimorphism and represented different on

Chromium (Cr) stable isotopes are a useful tracer of changes in redox conditions because changes in its oxidation state are accompanied by an isotopic fractionation. Recent co-precipitation experiments have shown that Cr(VI) is incorporated into the

One key to address the issue of the location of the K/Pg boundary at the Um Sohryngkew sections to look at Ccarb, Corg, Hg/TOC, Mo/Al chemostratigraphies, alongside Hg isotopes, in previous studied K/Pg sections in the Meghalaya area, and compare the

We report the occurrence of important carbon isotope excursions in early Paleozoic formations of the Eastern and Central Argentine Precordillera. The Steptoean positive isotope carbon excursion (SPICE) is known from North America, Kazakhstan, South C

We investigate the use of Hg as a proxy for volcanism by studying four distal and two proximal sections in relation to the Deccan volcanic center, straddling the Cretaceous-Paleogene (KPg) boundary at (a) Højerup (Denmark), Bottaccione and Padrician

Graptolite-bearing Middle and Upper Ordovician siliciclastic facies of the Argentine Precordillera fold-thrust belt record the disintegration of a longlived Cambro-Mid Ordovician carbonate platform into a series of tectonically partitioned basins. A

Silurian strata, as part of an Upper Ordovician to Lower Devonian siliciclastic succession, are widely distributed in the Central Precordillera of Western Argentina, but they are scarce in the Eastern Precordillera, and are not known with certainty i

There is a renewed interest in volcanism as the major trigger for dramatic climatic changes at the Cretaceous–Paleogene transition (KTB), which were accompanied by a decrease in biodiversity and mass extinction. We have used Hg contents as proxy fo
