Earth’s history has seen a mass extinction of ancient species caused by volcanoes. But new findings, recently published in the journal Science Advances, suggest that there may have been a volcanic eruption that created the conditions that allowed dinosaurs to colonize the world.
Event Carnian Pluvial Episode
The Carnian Pluvial Episode (CPE) was an extinction event that occurred approximately 233 million years ago. Large volcanic eruptions in western Canada are responsible for this event. By emitting large amounts of greenhouse gases, it causes rapid global warming and a continuous increase in rainfall for about a million years. The warm climatic conditions that followed and the growth of plants during this time created a wonderful and ideal environment for the dinosaurs to breed.
The CPE was not a major extinction, but its impact on the ecosystem immediately following it was significant. This event caused the extinction of 33% of marine species, but it set the stage for species diversification. This led to the formation of modern ecosystems and the evolution of mammals as well as corals, plankton and reptiles.
What do researchers say about the event?
This extinction event wiped out the species that had proliferated in the previous environment, leaving space for other groups to flourish in the post-disaster world. That’s how dinosaurs dominated the world back then.
Dr. Michael Rampino, a geologist at New York University, said: “The boat is a way of resetting evolution and the rulers of the times. You can think of it as a tree and you prune it away and it starts growing again. The branches that didn’t grow well before start to grow better but some of them are gone.” Volcanic eruptions and sudden climate change have caused disaster for many species – but in the end, it has allowed many others to thrive.”
