A revised seawater sulfate S-isotope curve for the Eocene
The sulfur isotope ratio (δ 34 S) recorded in marine barite is commonly used to estimate
secular changes in the sulfur isotopic composition of seawater sulfate (δ 34 S SO4) …

A 104-Ma record of deep-sea Atelostomata (Holasterioda, Spatangoida, irregular echinoids)–a story of persistence, food availability and a big bang
Deep-sea macrobenthic body fossils are scarce due to the lack of deep-sea sedimentary
archives in onshore settings. Therefore, hypothesized migrations of shallow shelf taxa into …
