It Once Rained for 2 Million Years on Earth and then Dinosaurs Reigned Superior

 

The Earth is still a whole sum of many riddles. The more we try to know it in depth about its origin and composition, the things became more complicated and shocking. 

One of them in the history of Earth is of the Carnian pluvial period, in which, it is founded that once it rained continuously for million years on Earth.

The continuous rain of many years always made scientists curious. This time period supported sprout life on Earth, and now the researcher believe they know why and how. 

At the period of Pangea, which was near about 200-300 million years before, the Earth was a huge supercontinent created by the whole world’s land mass. At that time our planet was totally at another location. 

Researchers thinks, at that period, there was a time where it rained for about one to two million years. In the 1970s and 80s, geologists detected abnormal layers in some of the old rocks that dated some 232-4 million years back.

One team of scientists in the eastern Alps observed a layer of siliclastic sedimentation added within carbonate creations, where as another team in the UK inspected a layer of grey rock planted within the renowned red stone feature of the place.

These two discoveries, in addition with several studies from separate areas of the world, came to a similar result - at one moment, the Earth had a long dry period and then rain begin.

Geologists were able to figure out that at the starting of the age of the dinosaurs, there was an abnormal wet period. 

This era has become to be called as the Carnian pluvial event, or Carnian pluvial episode. 

This charming event in the geological history of the Earth to make a significant need of why it began to rain for so long.

Researchers now thinks that the rise in humidity is responsible to a important surge in moisture levels, likely occurred by a massive volcanic explosion in the Wrangellia Large Igneous Province. Because of this, it rained for millions of years on earth. 

This incident probably cause increase in global temperatures, later warming the oceans and rising atmospheric moisture content.

A study issued in the Journal of the Geological Society recommended that the moist era was beneficiary for dinosaurs. 

This era of totally moister let them to diversify, following a tumultuous period decided by frequent volcanic explosions.

The scientists wrote - “In the alert vanishing of plants and main vegetarians on land, the dinosaurs were apparently the main advantageous at the period of reviving.”

"It probably have been one of the most significant [fast events] in the history of life in terms of its contribution in letting not only the ‘age of dinosaurs’ but also the beginnings of most key clades that made the modern fauna of terrestrial tetrapods, namely the turtles, crocodiles, lizards and mammals."
