Is the evolution of dinosaurs fueled by ice and not fire? Here’s the truth
A new study in the Proceedings of the National Academy of Sciences reveals that massive volcanic eruptions 201.6 million years ago initially caused cooling rather than warming. This rapid cooling, due to sulfur-rich particles blocking sunlight, led to a mass extinction and was followed by a prolonged warming period, paving the way for dinosaurs to thrive in the Jurassic period.
