Major events in Earth's history include the formation of the planet around 4.5 billion years ago, the development of life around 3.5 billion years ago, the formation of the first continents around 2.5 billion years ago, the rise and fall of dinosaurs during the Mesozoic era, and the evolution of humans in the last few million years. Additionally, significant climate changes, mass extinctions, and the movement of continents have shaped the history of Earth.

That's when a species or group of species no longer exists. The Dodo bird, for example, has gone extinct in recent history because all of them died out.
If an animal is endangered, it means that threats to its survival are considerable, and that action must be taken to ensure its continued existence. The koala is not currently endangered, but there are campaigns being mounted to have the koala listed as endangered, as threats to its survival are increasing, and there is concern that, if current trends continue, the koalas will be in imminent danger of exinction. If the koala were to be listed as endangered, it would mean higher levels of protection for the animal, particularly in reagrd to its habitat. Fewer housing and residential development would impact upon koala territory.
Prairie dog populations are greatly diminished below their numbers prior to the arrival of Europeans. The size of their habitat has also been greatly diminished. There are five species of prairie dog, three of which are least concern, but the Mexican and the Utah prairie dog are both listed as endangered.
The Paleogene was a geologic time period, the first of two periods of the Cenozoic era. It began 65.5 million years ago following the end of the Cretaceous Period, the last period of the Mesozoic Era. It ended 23 million years ago and was followed by the Neogene, the current period. During this time, Earth recovered from the mass exinction event that wiped out the dinosaurs and mammals became the dominant land animals. India collided with mainland Asia, forming the Himalayas, and ice sheets began to form in Antarctica.
