How did the mesozoic era end.

Mesozoic Era, second of Earth’s three major geologic eras of Phanerozoic time. Its name is derived from the Greek term for “middle life.” The Mesozoic Era began 252.2 million years ago, following the conclusion of the Paleozoic Era , and ended 66 million years ago, at the dawn of the Cenozoic Era . Visit—Mesozoic Parks. Every park contains some slice of geologic time. Here we highlight a few parks associated with Mesozoic Era. This is not to say that a particular park has only rocks from the specified period. Rather, rocks in selected parks exemplify a certain event or preserve fossils or rocks from a certain geologic age. This era was between about 250 to 66 million years ago. During this period, life evolved and diversified. It gets its name from the Greek language, which means ‘Middle life.’. This period is also famous as the age of dinosaurs or the age of reptiles. The Mesozoic era existed between the Paleozoic and the Cenozoic era.This era is popularly known as the “Age of Reptiles” and for good reason: reptiles, and particularly dinosaurs, were the dominant land-dwelling vertebrate animals at the time. During the Triassic, the first dinosaurs walked on the land, the first pterosaurs sailed through the skies, and the first ichthyosaurs and plesiosaurs swam in the oceans.

The Mesozoic is the middle of the three eras that make up the Phanerozoic eon. Before the Mesozoic was the Palaeozoic era. The K/T extinction in 65 mya also marks the beginning of the Cenozoic era, the one we live in. The three Mesozoic periods were: Triassic (252–201 mya) Lower Triassic (252–247 mya) Middle Triassic (247–237 mya)

The Paleogene is composed of the first three of these Epochs, (Paleocene, Eocene, and Oligocene Epochs).

Mesozoic. The Mesozoic Era was the geological era in which dinosaurs lived, as well as the first mammals. It lasted about 186 million years, starting 252.2 mya (million years ago) with the P/Tr extinction and ending 65 mya with the K/T extinction (the one that killed all dinosaurs except birds).
