There is a lot of discussion about how they disappeared from the earth, but in a new study it has been told how they evolved. According to this, about 230 million years ago, dinosaurs evolved on Earth with the help of huge volcanic eruptions and great monsoons. Researchers at the University of Birmingham analyzed sediments and plant fossils they found in a lake in China’s Jiyuan Basin.
Greenhouse gases started increasing
Based on chemical evidence, it is believed that the events of volcanic eruption were related to changes in the environment. This was the Carnian Pluvial Episode which took place between about 234 to 232 million years ago. After this the continents were separated from each other. During this mega-monsoon brought heavy rains and increased global temperature and humidity as greenhouse gas emissions began to rise.
environment was changing
In the report, researchers have said that huge volcanic eruptions, climate change, extinction of plants and animals were all going on simultaneously but dinosaurs were flourishing. During this the cone plants were growing. The lakes were deepening. According to the researchers, during this time, the drying environment helped special plants and animals living in such temperatures.
increase in mercury
In new research, changes during CPE have been linked to large-scale volcanic eruptions. These would have lasted for about 20 million years. With each explosion, the carbon cycle will be affected and climate change will occur. During this, the amount of mercury (mercury) used to increase very much, which used to get into the water through the land.
