Tutwuri.id – Before the appearance of the asteroid that hit the earth 66 million years ago, the Earth was ruled by various types of dinosaurs of various sizes.
There is still a lot of debate regarding the theory that is believed to be the cause of the emergence of ancient animals with sizes up to tens of meters.
Quoted from the publication of research results in the Proceedings of the National Academy of Sciences, a series of volcanic eruptions 250 million years ago helped strengthen the theory of dinosaur evolution.
Experts say that during the Triassic period, ecological changes occurred, causing mass extinctions and encouraging the evolution of dinosaurs.
Furthermore, in this era the dinosaurs were still in the form of reptiles until then Triceratops to Tyrannosaurus Rex appeared.
As reported by SciTech Daily, during the Triassic period there was a pause in the Late Triassic Carnian Pluvial Episode (CPE) where the temperature and humidity of the earth experienced a significant increase due to volcanic eruptions.
“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 is driving an increase in global temperature and humidity,” said Jason Hilton, professor at the University of Birmingham.
This ecological change is believed to be the driving force of the dinosaur era so that it experienced massive development.
The researchers also believe that this ecology is the optimal phase in which the dinosaurs were able to develop their species until they reached the dominance we saw 150 years ago.
Through the evidence of fossils found, researchers and archaeologists believe that the earth in 66 million years ago was still dominated by dinosaurs until an asteroid that hit the earth triggered its destruction.
