Burgener et al. (2019) Revisiting the equable climate problem during the Late Cretaceous greenhouse using paleosol carbonate clumped isotope temperatures from the Campanian of the Western Interior ...

The Cretaceous period happened from 145.5 to 65.5 million years ago. This was when more coastlines appeared. Seasons also became more evident as the planet’s climate became cooler.

The skies were empty for most of Earth’s history, but then light‑boned reptiles mastered powered flight roughly ...

For years, scientists have thought that a continental ice sheet formed during the Late Cretaceous Period more than 90 million years ago when the climate was much warmer than it is today. Now ...

After a temperature spike in the mid-Cretaceous, the climate began to cool, and the tenor changed. New Dinosaurs Though dinosaurs ruled throughout the Cretaceous, the dominant groups shifted and ...

Scientists have reconstructed the climatic development of the Arctic Ocean during the Cretaceous period, 145 to 66 million years ago. At that time the poles were devoid of ice and average ...

This swimming, dolphin-like reptile ruled the waters for more than 150 million years, spanning the early Triassic period to the late Cretaceous.

High levels of carbon dioxide and mild climate just 500 miles from South Pole allowed ... the general assumption was that the global carbon dioxide concentration in the Cretaceous was ...

Based on reconstructions of Arctic climate variability in the greenhouse world of the Late Cretaceous, Southampton scientists have concluded that man-made global warming probably would not greatly ...
