Le Paléogène, sur l'échelle des temps géologiques, est la plus ancienne période géologique du Cénozoïque. Succédant au Crétacé et précédant le Néogène, il s'étend de 66,0 à 23,03 millions d'années avant le présent .

The Palaeogene (meaning “old generation” in Greek) is the first geological period of the Cainozoic and the tenth period in the Phanerozoic eon.It began 65 million years ago, and ended 23 million years ago. Before it was the Cretaceous.The Palaeogene was followed by the Neogene.. The Palaeogene had three stages: Palaeocene, Eocene and Oligocene. The Palaeogene and the …

The Cretaceous–Paleogene (K–Pg) extinction event (also known as the Cretaceous–Tertiary (K–T) extinction) was a sudden mass extinction of three-quarters of the plant and animal species on Earth, approximately 66 million years ago. With the exception of some ectothermic species such as sea turtles and crocodilians, no tetrapods weighing more than 25 kilograms (55 …

The Paleocene Epoch is the 10 million year time interval directly after the K–Pg extinction event, which ended the Cretaceous Period and the Mesozoic Era, and initiated the Cenozoic Era and the Paleogene Period. It is divided into three ages: the Danian spanning 66 to 61.6 million years ago (mya), the Selandian spanning 61.6 to 59.2 mya, and the Thanetian spanning 59.2 to 56 mya.

- https://en.wikipedia.org/wiki/Climate_across_Cretaceous–Paleogene_boundary
The climate across the Cretaceous–Paleogene boundary (K–Pg or formerly the K–T boundary) is very important to geologic time as it marks a catastrophic global extinction event. Numerous theories have been proposed as to why this extinction event happened including an asteroid known as the Chicxulub asteroid, volcanism, or sea level changes.
- https://en.wikipedia.org/wiki/Neogene
The Neogene (/ ˈ n iː. ə ˌ dʒ iː n / NEE-ə-jeen), informally Upper Tertiary or Late Tertiary, is a geologic period and system that spans 20.45 million years from the end of the Paleogene Period 23.03 million years ago to the beginning of the present Quaternary Period 2.58 Mya. The Neogene is sub-divided into two epochs, the earlier Miocene and the later Pliocene.
