Triassic volcanic eruptions helped dinosaurs take over Earth

the Carnian stage (which spanned 237 to 227 million years) of the Triassic period marks one of the most significant intervals of the past 250 million years. Within two million years, the global biota underwent major changes, with dinosaurs becoming the dominant group on the planet. These events coincide with a remarkable interval of intense […]

Climate change caused by volcanic eruptions laid the groundwork for the rise of dinosaurs | Scientific and technological news

A new study has revealed how the rise of dinosaurs over 230 million years ago coincided with environmental changes brought on by massive volcanic eruptions. Known as the Carnian Rainfall of the Late Triassic (CEP), this interval of enormous climate change has seen temperatures and humidity rise across the globe. Prior to CPE, the climate […]

Volcanic eruptions may have caused the first “puffs” of oxygen in Earth’s atmosphere – ScienceDaily

A new analysis of 2.5 billion-year-old Australian rocks reveals that volcanic eruptions may have stimulated population surges of marine microorganisms, creating the first breaths of oxygen in the atmosphere. This would change the existing stories of Earth’s early atmosphere, which assumed that most changes in the early atmosphere were controlled by geological or chemical processes. […]

Have volcanoes stabilized the temperatures on the Earth’s surface?

London: A new study has found that volcanoes were responsible for stabilizing Earth’s surface temperatures and acted as a safety valve for Earth’s long-term climate. The results of the study were published in the journal “Nature Geoscience”. Scientists at the University of Southampton have discovered that vast chains of volcanoes were both responsible for the […]
