How long is a era?
An era in geology is a time of several hundred million years. It describes a long series of rock strata which geologists decide should be given a name. An example is the Mesozoic era, when dinosaurs lived on the Earth. An era is made up of periods, and several eras make up an eon.
What was the first era?

How many eras are there in history?
One of the ways history is commonly divided is into three separate eras or periods: the Ancient Period (3600 BC – 500 AD), the Middle Ages (500 -1500), and the Modern Era (1500-present).
What are the 4 eras in order?

What is the shortest era?
Phanerozoic EonThe Quaternary spans from 2.58 million years ago to present day, and is the shortest geological period in the Phanerozoic Eon. It features modern animals, and dramatic changes in the climate. It is divided into two epochs: the Pleistocene and the Holocene.
How is time divided in history?
