It is well established that greenhouse conditions prevailed during the Cretaceous Period (~
145–66 Ma). Determining the exact nature of the greenhouse-gas forcing, climatic warming …

The Cambrian diversification of animals was long thought to have begun with an explosive
phase at the start of the Tommotian Age. Recent stratigraphic discoveries, however, suggest …

Foundering of mafic lower continental crust into underlying convecting mantle has been
proposed as one means to explain the unusually evolved chemical composition of Earth's …

Very similar high‐resolution δ13Ccarb and δ13Corg curves are reported for the early Aptian
“Livello Selli”(LS, oceanic anoxic subevent 1a) at two pelagic successions of the Alpine …

The Early Cretaceous carbonate carbon isotope record is marked by three positive high-
amplitude (> 1.5‰) excursions each covering time spans of more than 106 years. They are …

The best–documented example of rapid climate change that characterized the so–called
'greenhouse world'took place at the time of the Palaeocene–Eocene boundary: introduction …

The geological and paleoenvironmental setting and the vertebrate taxonomy of the
fossiliferous, Cenomanian-age deltaic sediments in eastern Morocco, generally referred to …

The tectonics, geography and climate of the Cretaceous world were very different from the
modern world. At the start of the Cretaceous, the supercontinent of Pangaea had just begun …

General circulation models (GCMs) use the laws of physics and an understanding of past
geography to simulate climatic responses. They are objective in character. However, they …

The Cretaceous is a special episode in the history of the Earth named for a unique rock type,
chalk. Chalk is similar to modern deep-sea calcareous ooze and its deposition in …
