During this era, Eutherian ...Quaternary, in the geologic history of Earth, a unit of time within the Cenozoic Era, beginning 2,588,000 years ago and continuing to the present day. The Quaternary has been characterized by several periods of glaciation (the “ice ages” of common lore), when ice sheets many kilometres thick have The Eocene is the second of five epochs in the Tertiary Period the second of three epochs in the Paleogene and lasted from about 55.8 to 33.9 million years ago.*. The oldest known fossils of most of the modern orders of mammals appear in a brief period during the early Eocene and all were small, under 10 kg.
The initial epoch of the Paleogene Period and the Cenozoic Era is the Paleocene Epoch, which marks the first subdivision of geologic time after the extinction of the dinosaurs and the end of the Cretaceous Period. In western North America, the uplift of the Rocky Mountains, which started in the Cretaceous, continued throughout the Paleocene.Most of the sharks on the planet have developed in the Cenozoic era, except for the truly ancient sharks from the Cretaceous period. The newest shark species to enter the water is the Hammerhead Shark. Hammerhead Shark evolution only dates back about 20 million years. ….

The start of the Quaternary period, the last and current period of the Cenozoic, is marked by the start of our current ice age 2.58 million years ago. During this time period, ice sheets advanced and retreated, most likely due to Milankovitch cycles (see Chapter 15 ).The Cenozoic era is the time period beginning 66 million years ago and continuing to the present day. During this time period, plate tectonic activity has played a major role in the Earth's geological evolution, shaping and forming many of the features of the planet's surface we see today. Plate tectonics cause the movement of Earth's crust ...The stepwise cooling marks the long-time global climate change during the Cenozoic, particularly since the Oligocene/Eocene boundary. This climatic evolution has been punctuated by several warming such as the peak Cenozoic warmth at 52. Asian deserts. The transition from a warm “greenhouse” to a colder “icehouse” world at ∼34 …
