Nov 30, 2018 · As we’ve found, the Cretaceous Period is the third of three periods that make up the Mesozoic Era. The first period of the Mesozoic Era was the Triassic Period. It began 251.9 million years ago (Mya) and ended 201.3 Mya. The second period was the Jurassic Period, which spanned from 201.3 Mya to 145 Mya. The Quaternary ( / kwəˈtɜːrnəri, ˈkwɒtərnɛri / kwə-TUR-nə-ree, KWOT-ər-nerr-ee) is the current and most recent of the three periods of the Cenozoic Era in the geologic time scale of the International Commission on Stratigraphy (ICS). [4] It follows the Neogene Period and spans from 2.58 million years ago to the present. [5]The K/Pg extinction marked the end of the Mesozoic Era and the beginning of the Cenozoic Era, the Era that we live in today. At the beginning of the Cenozoic, the world’s continents and ocean basins were very similar to those that exist today, though the continents have continued to shift. Shifting Plates

Climate change is well documented [1] and mammals have a good fossil record during this interval. Thus, potentially, the two can be used to compare environments and evolution.The Mesozoic era and the long reign of the dinosaurs ended around 66 mya with another dramatic mass extinction in which most of the dinosaurs were wiped out.

The Phanerozoic eon is divided into three eras: the Palaeozoic, an era of arthropods, amphibians, fishes, and the first life on land; the Mesozoic, which spanned the rise, reign of reptiles, climactic extinction of the non-avian dinosaurs, the evolution of mammals and birds; and; the Cenozoic, which saw the rise of mammals.Cenozoic (66 million years ago until today) means ‘recent life.’ During this era, plants and animals look most like those on Earth today. Periods of the Cenozoic Era are split into even smaller parts known as Epochs, so you will see even more signposts in this Era. The two most prominent warm phases in Earth history occurred during the Mesozoic and early Cenozoic eras (approximately 252 million to 35 million years ago) and the early and mid-Paleozoic (approximately 500 million to about 359 million years ago).
