Dinosaur was the ruler of Planet Earth, before an asteroid impact wiped them out about 66 million years ago. What caused the dinosaur to be the dominant animal and its variety?
A group of scientists in research published in the Proceedings of the National Academy of Sciences said that massive volcanic eruptions helped create the era of the dinosaurs.
In the Triassic period which began about 250 million years ago, there was a massive ecological change where there was a mass extinction. Dinosaur began to appear in this era and was still in the form of an ordinary reptile, until it later turned into Triceratops or Tyrannosaurus Rex.
As quoted detikINET from SciTech Daily, during the Triassic period there was a Late Triassic Carnian Pluvial Episode (CPE), where there was an increase in Earth’s temperature and humidity. This incident coincided with intense volcanic activity.
“Our research shows that this period can be divided into four distinct events, each event triggered by powerful volcanic activity associated with the release of large amounts of carbon dioxide into the atmosphere. This led to an increase in global temperature and humidity,” said Jason Hilton, professor at the University of Birmingham.
There are also periods when it rains very intensely. At that time, plant species that can not adapt to extinction, as well as animal species that are in the water and land.
“The changes freed up ecological space for other groups of organisms, such as the dinosaurs, to thrive,” Hilton added.
“At the time, dinosaur “The species are just starting to develop and it’s likely that without that event, they would never have achieved the ecological dominance we see running for the next 150 million years,” said Dr Emma Dunne, an expert from the University of Birmingham.
