Paleomagnetic study of Jurassic and Cretaceous rocks north of San Marcos fault, central Coahuila, México. [PDF]

Geofísica Internacional, 2008
Upper Jurassic and Lower Cretaceous continental strata at Potrero Colorado, in the core of Sierra La Fragua anticline in central Coahuila, carry dual-polarity characteristic magnetizations that we interpret as near primary chemical remanent ...

Microbial mats in dinosaur ichnocoenoses

Sedimentology, EarlyView.
ABSTRACT Until now, the significance of microbial mats in preservation of dinosaur tracks and in reconstructing the palaeoenvironment in which dinosaurs roamed was rarely studied. Dinosaur tracks are commonly found close to ancient aquatic bodies where moist sediment had once allowed footstep registration.

Climate conditions on the South‐Iberian Palaeomargin during the latest Pliensbachian to early Toarcian: A mineralogical and geochemical study from hemipelagic deposits

Sedimentology, EarlyView.
ABSTRACT The integrated analysis of lithofacies, mineralogy and geochemistry of the hemipelagic marine succession exposed in La Cerradura section (South‐Iberian Palaeomargin) provides new information to characterise the palaeoenvironmental conditions during the latest Pliensbachian to early Toarcian, including the Jenkyns Event.

Jurassic Paleomagnetic Data From the Eastern Tethyan Himalaya Support a Smaller Greater India

Geophysical Research Letters
Knowledge of the original dimension of Greater India in the Jurassic Period is critical for reconstructing the paleogeographic framework of Gondwana. However, two end‐member reconstructions for Greater India (≤1,000 or ≥2,000 km) exist in the Jurassic ...
