TL;DR: In this paper, the elemental and isotopic composition of belemnite calcite were studied in Pliensbachian and Toarcian sections from the Yorkshire coast, UK, and Southern Germany, to investigate oceanographic change during an interval prior to and including the Toarcians Oceanic Anoxic Event (OAE).

TL;DR: In this paper, a crossplot of Mo/total organic carbon (TOC) profiles through the Lower Toarcian black shales of the Cleveland Basin, Yorkshire, United Kingdom, and the Posidonia shale of Germany and Switzerland reveal water mass restriction during the interval from late tenuicostatum Zone times to early bifrons Zone times, times which include that of the putative Early Toarcians oceanic anoxic event.

TL;DR: In this paper, the authors present pollen, spore and geochemical analyses across the Triassic/Jurassic boundary from three drill cores from Germany and Sweden and conclude that the terrestrial vegetation shift is so severe and wide ranging that it is unlikely to have been triggered by greenhouse warming alone.

TL;DR: In this paper, the authors used belemnites from SE France and SE Spain to study the early Cretaceous time of delta C-13, delta O-18, Mg/Ca, and Sr-87/Sr-86 in calcite, and delta O18 in seawater.

TL;DR: In this article, the authors present C isotope records from belemnites (delta(13)C(bel)) sampled from two localities, calibrated with high-resolution ammonite biostratigraphy and Sr isotope stratigraphy, in Yorkshire (England) and Dotternhausen (Germany), that can be used to assess which model best explains the observed changes in carbon isotopes.
