Geologic Time Scale: Cretaceous Campanian Stage

(83.6 to 72.1 million years ago)

The Cretaceous Period is the third and final period of the Mesozoic and the longest period of the Phanerozoic Eon. The period as first defined by Belgian geologist Jean d’Omalius d’Halloy in 1822 as the Terrain Cretace, using starta (layers) in the Paris Basin and names for the extensive beds of chalk(calcium carbonate deposited by the shells of marine invertebrates, principally coccoliths), found in the upper Cretaceous of Western Europe. The name is derived from the Latin creta meaning “chalk”, which is abundant in the later half of the period.

During the Cretaceous, the late-Paleozoic-to-early-Mesozoic supercontinent of Pangaea completed its tectonic breakup into the present-day continents, although their positions were substantially different at the time. The Earth’s Climate was warmer than today, and sea level was much higher. The end of the Cretaceous period (along with the Mesozoic) ended with the Cretaceous-Paleogene extinction event (formerly known as the KT boundary). 

Campanian Age/Stage

Late Cretaceous: 83.6 to 72.1 million years ago

The Campanian Epoch is the second to last age in the Late Cretaceous Period. The time is known for high dinosaur diversity and rising sea levels all around the world. The most well know of these seas was the North American western interior seaway. In 1857 Henri Coquand named the Campainian after the western French village of Champagne.
