Dinosaurs, the deadliest creatures in the world, may have had humble beginnings and had to wait for time. It happens when Earth’s volcanoes change the climate and create new Earth ecosystems. Called the ‘Carnian Pluvial Event’ (CPE), research published in the journal Science Advances suggests this is what caused a third of all marine life to go extinct. Including many land plants and animals about 234 million years ago.
Jacopo Dal Corso, a geologist at the University of Leeds in the UK, said: Volcanoes release huge amounts of carbon dioxide into the atmosphere. This increased the temperature and caused a ‘hydrological cycle’ lasting 2 million years. But it’s a geologic blink.
Evidence is that the amount of mercury, a volcanic eruption, has entered the lake and infiltrated the soil, accumulating in layers. The team also found that the proportion of carbon dioxide in the fossils had changed. It was as if those animals had grown up in dry air before. and become organisms that thrive in warm and humid climates
“For the first time, mercury and carbon isotope data are well correlated in CPE,” said Andrea Marzoli, a igneous petrobiologist at the University of Padua in Italy.
According to the report, CPE is a circulation that paves the way for a new colony of power. When it rains, it creates a wet environment. Moisture-loving plants and animals evolved, including frogs, lizards, crocodiles, turtles, and dinosaurs. Many pines appeared for the first time during this period as well, thus the CPE formed the foundation of modern ecosystems.
Previous studies estimated that The volcano has erupted and released at least 5,000 gigatons of carbon dioxide into the atmosphere. This is hundreds of times more than the current annual global emissions. Heavy rain has become a norm. and living beings died in great numbers.
“After the widespread extinction of important terrestrial plants and herbivores, Dinosaurs appeared to be the main beneficiaries during the regeneration period. It is rapidly expanding in diversity. spread across different regions and continents,” the report said.
from fossil data Pre-CPE dinosaurs account for only 5% of all fossils found. But when it starts to rain The numbers skyrocketed. by more than 80 percent of the fossils found after this event
after the rain stops The air on the Pangea Continent was dry again. But life on Earth has changed forever. The vegetation is completely restored by the conifers, which are scattered throughout. more importantly Fierce and diverse creatures have begun a new period on Earth. and will live hundreds of millions of years later
“It was probably one of the most rapid and significant events in the history of life. It was also the origin of the main group of life that would form modern terrestrial animals such as turtles, crocodiles, lizards and mammals,” said Jacobo Dal Corso.
