Abstract The global Hangenberg Crisis near the Devonian–Carboniferous boundary (DCB)
represents a mass extinction that is of the same scale as the so-called 'Big Five'first-order …

Euxinic ocean conditions accompanied significant events in Earth history, including several
Phanerozoic biotic crises. By critically examining modern and ancient euxinic environments …

Icehouses are the less common climate state on Earth, and thus it is notable that the longest-
lived (c. 370 to 260 Ma) and possibly most extensive and intense of icehouse periods …

Conodonts, microfossils composed of carbonate-fluor apatite, are abundant in Palaeozoic–
Triassic sediments and have a high potential to preserve primary oxygen isotope signals. In …

Variations in the 18 O/16 O ratio of marine fossils and microfossils record changes in
seawater 18 O/16 O and temperature and provide the basis for global correlation. Based on …

Fishes include more than half of all living animals with backbones, but large‐scale
palaeobiological patterns in this assemblage have not received the same attention as those …

Chrono-, litho-and biostratigraphy across the Devonian–Carboniferous transition are
reviewed to provide a precise time framework for the global Hangenberg Crisis and for the …

Three glacial episodes are identified in Upper Devonian and Mississippian strata in South
America using sedimentologic, stratigraphic, paleontological, bore hole, and outcrop data …

Carbon isotopes of whole rock carbonates and oxygen isotopes of conodont apatite from
Late Devonian to Early Pennsylvanian sections in Europe and Laurentia were measured in …

The oceans of the early Cambrian (~ 541 to 509 million years ago) were the setting for a
marked diversification of animal life. However, sea temperatures—a key component of the …
