The present ice age began about 2.6 million years ago and it has not ended yet. We are in a warm period within an ice age. The last glaciation started about 110,000 years ago and ended about 10,000 years ago.
Paleozoic, Mesozoic, and Cenozoic refer to periods in Earth's history. The Paleozoic era began 542 million years ago and ended 251 million years ago. The Mesozoic era is the age of dinosaurs and was from 245 to 66 million years ago. The Cenozoic period began 65 million years ago and continues today.
We are in an Ice Age now, although in an inter-glacial period when most ide has retreated for a time. The current Ice Age began more than a million years ago. The most recent glacial period ended about 10000 years ago, so about 8000 BC.
The Carboniferous is considered to have started 354 million years ago and ended 290 million years ago.
The Mesozoic period began about 250 million years ago when the Permian-Triassic extinction occurred, probably by a combination of gradual atmosphere change and some external event like an Earth impact. The period ended about 66 million years ago with another great extinction, this one probably a combination of an impact and volcanic activity.
The Precambrian Era began in the time period 4600 and ended in 570.
The Mesolithic period ended around 5,000 to 4,000 years ago, transitioning into the Neolithic period as societies began to shift towards farming and agriculture. This period marked a significant change in human societies as they began to settle in one place and domesticate plants and animals.
The seven years war began in 1756 and ended in 1763.
The Gothic period of literature lasted about 100 years. It began in the latter part of the 18th century and ended about 1900.
The present ice age began about 2.6 million years ago and it has not ended yet. We are in a warm period within an ice age. The last glaciation started about 110,000 years ago and ended about 10,000 years ago.
The Quaternary Period began 2.6 million years ago.
We are in the Quaternary period now (Holocene Epoch). So it hasn't ended yet.
The cretaceous period!!! First it was the Triassic period about 200-250 million yrs ago then it was the Jurassic Period and then about 135 million yrs ago the cretaceous period started and then it ended about 65 million yrs ago. This was the period when the t-rex was alive along with ankylosaurus, velociraptor, triceratops and iguanodon. Hope this helpsss!!! from Megggannn
The Cretaceous period ended with the extinction of the dinosaurs. The period that followed the mass extinction was called the Paleocene. This was a time of the mammals.
The Jurassic period extended from 200 million BCE to 146 million years BCE. It lasted 54 million years.
The Devonian Period is a part of the Paleozoic Era, which covers the time from 541 to 252.17 million years ago. It began with the Cambrian explosion, in which most phyla of life began, and ended with the mass extinction called the Permian-Triassic extinction event.
The Edo Period, also known as the Tokugawa Period, was the period in time in which the Tokugawa Shogunate controlled Japan. This period lasted roughly from 1603-1868. It began with the coming to power of Tokugawa Ieyasu and ended with the Meiji Restoration.
