Abstract The Late Cretaceous was a greenhouse world, characterized by elevated
temperatures and high atmospheric pCO2. Even in the context of an extreme greenhouse …

The nature of the warm climates of the Cretaceous has been enigmatic since the first
numerical climate models were run in the late 1970s. Quantitative simulations of the …

Water isotopes are an important tool for reconstructing the amount of atmospheric lifting
related to high topography in the geologic past. However, our capacity for meaningful …

An epicontinental sea bisected West Africa periodically from the Late Cretaceous to the early
Eocene, in dramatic contrast to the current Sahara Desert that dominates the same region …

A wealth of Earth-sized exoplanets will be discovered in the coming years, providing a large

An average of concentrations of Na+, Mg 2+, Ca 2+, K+, and Cl–in fluid inclusions, from the
Khorat Plateau evaporite primary halite, was employed. The evaporation–crystallization …

We identified and described Potomac Formation paleosols from three coreholes in New
Jersey and Delaware to interpret depositional history and reconstruct regional landscapes …

Non-ophidian ophidiomorphs, colloquially referred to as 'dolichosaurs,'are small-bodied
aquatic lizards that lived in shallow seaways, rivers, and reef environments during the Late …
