The Cretaceous (IPA: / k r ɪ ˈ t eɪ ʃ ə s / krih-TAY-shəss) [2] is a geological period that lasted from about 143.1 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest.
The Jurassic North Atlantic Ocean was relatively narrow, while the South Atlantic did not open until the following Cretaceous Period, when Gondwana itself rifted apart. [46] The Tethys Sea closed, and the Neotethys basin appeared. Climates were warm, with no evidence of glaciation. As in the Triassic, there was apparently no land near either ...

Here are some fun map facts for you: one of the oldest surviving maps is the Babylonian Map of The World. Archaeologists date it back to around 700 to 500 B.C. The map was a clay tablet nearly the ...
A map showing the location of the large igneous provinces of the world. The Deccan Traps are represented by the purple region in India. 1972. Peter Vogt reported evidence of intense volcanic activity occurring in India around the end of the Cretaceous. He hypothesized that this volcanic activity released poisonous trace elements which brought ...
In the geological timescale, the Berriasian is an age/stage of the Early/Lower Cretaceous. It is the oldest subdivision in the entire Cretaceous. It has been taken to span the time between 143.1 ±0.6 Ma and 137.05 ± 0.2 (million years ago). [2] The Berriasian succeeds the Tithonian (part of the Jurassic) and precedes the Valanginian.
