Jurassic climate mode governed by ocean gateway
The Jurassic (∼201–145 Myr ago) was long considered a warm ‘greenhouse' period; more recently cool, even ‘icehouse' episodes have been postulated. However, the mechanisms governing transition betweenExpand

Onset of main Phanerozoic marine radiation sparked by emerging Mid Ordovician icehouse
The Great Ordovician Biodiversification Event (GOBE) was the most rapid and sustained increase in marine Phanerozoic biodiversity. What generated this biotic response across Palaeozoic seascapes is aExpand

Diagenetic alteration in low-Mg calcite from macrofossils: a review
The quality of palaeoenvironmental reconstructions based on macrofossil carbonate critically depends on preservation of the shell material because post-depositional processes can modify itsExpand

Permian strontium isotope stratigraphy
Abstract The secular evolution of the Permian seawater 87Sr/86Sr ratios carries information about global tectonic processes, palaeoclimate and palaeoenvironments, such as occurred during the EarlyExpand

Evolution of the Toarcian (Early Jurassic) carbon-cycle and global climatic controls on local sedimentary processes (Cardigan Bay Basin, UK)
The late Early Jurassic Toarcian Stage represents the warmest interval of the Jurassic Period, with an abrupt rise in global temperatures of up to ∼7 °C in mid-latitudes at the onset of the earlyExpand

Stable isotope records across the Cretaceous-Paleogene transition, Stevns Klint, Denmark: New insights from the chromium isotope system
Abstract Late Cretaceous to Early Paleogene time represents a critical transitional period in Earth history. Global events include short-term instability in climate and ocean circulation, largeExpand

Tectonic forcing of Early to Middle Jurassic seawater Sr/Ca
The Jurassic Period (ca. 201–145 Ma) is marked by fundamental reorganizations of paleogeography, paleoceanography, ecosystems, and the progressive shift from aragonite to calcite as the favoredExpand

Discrepancy between Sr isotope and biostratigraphic datings of the upper middle and upper Miocene successions (Eastern North Sea Basin, Denmark)
Abstract One hundred and fifty-six 87Sr/86Sr analyses have been performed on 129 samples from 18 outcrops and boreholes in Oligocene–Miocene deposits from Jylland, Denmark. These analyses were mainlyExpand

The lower Maastrichtian Hvidskud succession, Møns Klint, Denmark: calcareous nannofossil biostratigraphy, carbon isotope stratigraphy, and bulk and brachiopod oxygen isotopes
The lower Maastrichtian Hvidskud succession, Møns Klint, Denmark abundant Thalassinoides burrows (Figs 2, 3). Previous stratigraphic studies of the succession are based on foraminifera, coccoliths,Expand

Discerning primary versus diagenetic signals in carbonate carbon and oxygen isotope records: An example from the Permian–Triassic boundary of Iran
Abstract Sedimentary successions across the Permian–Triassic boundary (PTB) are marked by a prominent negative carbon isotope excursion. This excursion, found in both fossil (e.g., brachiopod) andExpand
