The Permian was a period of great blossoming for tetrapods. Lutgens & Tarbuck further subdivide this time period into the Paleocene Epoch (65-54.8Myr), the Eocene Epoch (54.8-33.7Myr), and the Oligocene Epoch (33 . Mammals thrived during this period after the extinction of the dinosaurs in the Cretaceous Period. It is the traditional name for the first of two periods in the Cenozoic Era ( 66 million years ago to the present); the second is the Quaternary Period (2.6 million years ago to the present). The Paleogene Period is the first of three periods in the Cenozoic Era. The Tertiary. - Eocene 55-34 mill. As the longest geological Period, the Cretaceous constitutes nearly half of the Mesozoic. The Tertiary period begins with the catastrophe that killed off the dinosaurs at the end of the Cretaceous Period, about 65 million years ago.And the Tertiary lasts down to 1.8 million years ago. Therefore, it is called the KT extinction. In brief, this incredibly long period of time, measured in "mya" or "millions of years ago," saw the development of dinosaurs, marine reptiles, fish, mammals, flying animals including pterosaurs and birds, and a huge range of plant life. By the end of this period, primates rose to prominence, as did Great Apes and Homo sapiens as well.

The Cenozoic, sometimes known as the "Age of Mammals", as the Mesozoic was the "Age of Reptiles", is known by its Epochs. Soft-bodied animals are well represented in these faunas. The period itself lasted over 63 million years and contained five separate epochs: the Paleocene, the Eocene, the Oligocene, the Miocene and the Pliocene.

The Paleogene Period (or the early part of the Tertiary Period) represents the time period after the major extinction that wiped out the dinosaurs and about half of the known species worldwide. The surviving group of dinosaurs were avians, ground and water fowl who radiated into all modern species of bird. The earliest epoch, the Paleocene Epoch , ranges from approximately 65 mya to 55 mya. The Tertiary Period began abruptly when a meteorite slammed into the earth, leading to a mass extinction that wiped out about 75 percent of all species on Earth, ending the reptile-dominant Cretaceous Period and Mesozoic Era. from about 145 to 133 million years ago to the beginning of the Paleocene of the Tertiary Period (about 66 to 56 Ma)). The Cretaceous-Tertiary Extinction. This scheme is reflected in the International Commission on Stratigraphy's stratigraphic chart this page follows.

Cambrian Period (Paleozoic Era) 544-505. It is the traditional name for the first of two periods in the Cenozoic Era (66 million years ago to the present); the second is the Quaternary Period (2.6 million years ago to the present). Four additional Epochs comprise the Neogene and Quaternary Periods that The Cretaceous-Tertiary extinction event was a mass extinction which occurred an estimated 65.5 million years ago, wiping out a substantial number of the species on Earth. Amphibians, anapsids, diapsids, and synapsids grew to great sizes. This event formed the Cretaceous-Tertiary, or K-T, boundary.
