What era was 2 million years ago?
Geological Eras
The Cenozoic is divided into the Tertiary (from 65 million years ago until 2 million years ago) and Quaternary (2 million years ago to the present) periods.
What era was million years ago?
Mesozoic Era, second of Earth's three major geologic eras of Phanerozoic time. Its name is derived from the Greek term for “middle life.” The Mesozoic Era began 252.2 million years ago, following the conclusion of the Paleozoic Era, and ended 66 million years ago, at the dawn of the Cenozoic Era.Nov 13, 2022
What epoch was million years ago?
Eocene Epoch, second of three major worldwide divisions of the Paleogene Period (66 million to 23 million years ago) that began 56 million years ago and ended 33.9 million years ago. It follows the Paleocene Epoch and precedes the Oligocene Epoch.
What is the oldest era called?
The oldest subdivision of the time scale is the Precambrian (symbolized by PC, X, Y, or Z in the GRI GIS data). The Precambrian is split into three eons: Hadean (4600-4000 MYA), Archean (4000-2500 MYA), and Proterozoic (2500-541 MYA).Oct 5, 2021
What was the era 100 million years ago?
The Early Cretaceous spans from 145 to 100 million years ago.
What epoch was 2 million years ago?
calculated that roughly 2 million years ago, around the end of the Pliocene Epoch, a group of bright O and B stars called the Scorpius–Centaurus OB association passed within 130 light-years of Earth and that one or more supernova explosions gave rise to a feature known as the Local Bubble.
What time period was 2 million years ago?
Geological Eras
The Cenozoic is divided into the Tertiary (from 65 million years ago until 2 million years ago) and Quaternary (2 million years ago to the present) periods.
