They triggered disappearances of numerous species, genera, families, and even high-order groups of marine organisms, and they were often associated with outstanding environmental catastrophes such as global events of anoxia and euxinia, unusual warming and planetary-scale glaciations, massive ...
The Mesozoic (from the Greek prefix meso meaning “between” and zoon, animal or "living being") era is an interval of about 186 million years defined on the geologic timescale as spanning roughly from 251 to 65 million years ago (mya), and as being the second of three eras of the Phanerozoic eon.

Humans subdivide time into useable units such as our calendar year, months, weeks, and days; geologists also subdivide time. They have created a tool for measuring geologic time, breaking it into useable, understandable segments. For the purposes of geology, the “calendar” is the geologic time scale.

The third major mass extinction was during the last period of the Paleozoic Era, called the Permian Period. This is the largest of all known mass extinctions with a massive 96% of all species on Earth completely lost. It is no wonder, therefore, that this major mass extinction has been dubbed “The Great Dying.”The Quaternary Period (2.6 million years ago to the present) is composed of the Pleistocene and Holocene epochs. The Holocene Epoch began 11,700 years ago and continues into modern time. The vast interval of time that spans Earth’s geologic history is known as geologic time.
