Welcome to Megalayense. This is the name of the current geological period of the Earth
The designation was made by the International Stratigraphy Commission of the International Union of Geological Sciences and comes with controversy because of others experts have proposed the name Anthropocene.
Geologists divide the 4,600 million years of the Earth into different ages, ages, periods, and stages. by the emergence of certain species of plants or animals.
The Megalayense refers to the period of history that begins 4,200 years ago to the present day.
A great drought of two centuries marks the beginning of this age, which is known as the Holocene series, which is in turn in the Quaternary period (Cenozoic era, Eon Fanerozoic).
For example, dinosaurs lived in the same eon as us (Fanerozoic) but in the previous era, Mesozoic (251 million and 66 million years ago). While life emerged 3,460 million years ago, which corresponds to the Paleo-archaic Era of Precambrian Eon
Three Steps
Geologists have decided to divide the Holocene in three stages, including everything that happened 11,700 years ago. The last ice age has ended.
In addition to Megalayense, the most recent are Greenland (11,700-8,300 years) and Norgripian (8,300-4,200 years).
The drought that marks the beginning of this last stage serious consequences in the populations that inhabited Egypt, Greece, Mesopotamia and regions of China and India.
The best record of this drought can be seen from mineral deposits in the Megalaya Caves (India). From where his name
Controversy
However, some experts believe that it is the human activity that has had the greatest impact on the planet in recent years . "After studying seven years ago and considering several committees, they make a sudden announcement and change the scheme," BBC professor Mark Maslin, a professor of geography at University College London, told BBC. and one of the leading scientists in the debate on the Anthropocene
He added: "Now, it is official, we are in a new era, who would say it? We now have some definitions that (…) may go against most scientists see it as the most significant change on Earth over the last 10,000 years. "
