During the Cenozoic, mammals proliferated from a few small, simple, generalised forms into a diverse collection of terrestrial, marine, and flying animals, giving this period its other name, the Age of Mammals. The Cenozoic is just as much the age of savannas, the age of co-dependent flowering plants and insects, and the age of birds. [40]
The categorisation of the past into discrete, quantified named blocks of time is called periodization. [1] This is a list of such named time periods as defined in various fields of study.
The Meghalayan age is the name given in 2018, by the International Commission on Stratigraphy, to the current age or latest geologic age – or uppermost stage of the Quaternary. [3] It is also the upper, or latest, of three subdivisions of the Holocene epoch or series .

Quaternary science is the systematic study of the Quaternary Period. It is a rapidly changing field with new research techniques being developed e.g. new dating techniques. Quaternary science is a field of study which involves geography, biology, chemistry, and physics. [4]
The Quaternary Period, the Cenozoic Era geologic time unit from the end of the Pliocene Epoch, roughly 1.8−1.6 million years ago, to the present day. The Quaternary has 2 geologic/geochronologic subdivisions, the Pleistocene and the Holocene Epochs .

Vertical axis scale: Millions of years ago The European Land Mammal Mega Zones (abbreviation: ELMMZ , more commonly known as European land mammal ages or ELMA ) are zones in rock layers that have a specific assemblage of fossils ( biozones ) based on occurrences of fossil assemblages of European ...
