The Cretaceous (along with the Mesozoic) ended with the Cretaceous–Paleogene extinction event, a large mass extinction in which many groups, including non-avian dinosaurs, pterosaurs, and large marine reptiles, died out, widely thought to have been caused by the impact of a large asteroid that formed the Chicxulub crater in the Gulf of Mexico.

Byblos (whc.unesco.org) The ruins of many successive civilizations are found at Byblos, one of the oldest Phoenician cities. Inhabited since Neolithic times, it has been closely linked to the legends and history of the Mediterranean region for thousands of years. Byblos is also directly associated with the history and diffusion of the Phoenician alphabet.

Cretaceous (Wikipedia) The Cretaceous (IPA: /krɪˈteɪʃəs/ krih-TAY-shəs) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 79 million years, it is the longest geological period of the entire Phanerozoic. The name is derived from the Latin creta, “chalk”, which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation Kreide.
