Lethally Hot Temperatures During the Early Triassic Greenhouse
Too-Hot Times Climate warming has been invoked as a factor contributing to widespread extinction events, acting as a trigger or amplifier for more proximal causes, such as marine anoxia. Sun et al.Expand

Oxygen isotope fractionation in marine aragonite of coralline sponges
Oxygen isotope values of the extant Caribbean coralline sponge Ceratoporella nicholsoni are compared with published temperatures and δ18O of water calculated from salinities. The measured values fromExpand

Anoxic events in the late Frasnian—Causes of the Frasnian-Famennian faunal crisis?
Carbon isotope data collected from five Frasnian-Famennian boundary sections in central Europe show two positive δ 13 C excursions in the late Frasnian (∼367 Ma). Both anomalies coincided with theExpand

Climate warming in the latest Permian and the Permian-Triassic mass extinction
High-resolution oxygen isotope records document the timing and magnitude of global warming across the Permian-Triassic (P-Tr) boundary. Oxygen isotope ratios measured on phosphate-bound oxygen inExpand

Carbon isotope stratigraphy of the Devonian of Central and Southern Europe
Abstract Carbonate rocks of the Rhenohercynian and Saxothuringian zones of the Variscan Mountains, Prague Syncline, Carnic Alps, Montagne Noire, Pyrenees, and Cantabrian Mountains were investigatedExpand

Carbon isotope geochemistry of the Frasnian–Famennian transition
Abstract Carbon isotope records for inorganic and total organic carbon (TOC) as well as for individual organic biomarkers show two positive excursions in the Late Frasnian with comparable shape andExpand

Carbon isotope records from extant Caribbean and South Pacific sponges: Evolution of δ13C in surface water DIC
Stable isotope records of demosponges from the Caribbean and Coral Sea are described for the purpose of studying the influence of fossil fuel CO2 on the carbon isotopic composition of dissolvedExpand

Devonian climate and reef evolution: Insights from oxygen isotopes in apatite
article i nfo 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 orderExpand

Climatic ups and downs in a disturbed Jurassic world
The tropical, warm, and equable climate of the Jurassic world is regularly challenged by geoscientists, especially since oxygen isotopes (δ 18 O) of fossil hardparts have been used to reconstruct theExpand

Deciphering kinetic, metabolic and environmental controls on stable isotope fractionations between seawater and the shell of Terebratalia transversa (Brachiopoda)
This study presents carbon and oxygen stable isotope data obtained from high-resolution sampling (<500 μm) of the brachiopod Terebratalia transversa from the San Juan Islands (Washington State, USA).Expand
