The researchers studied the impact of plate tectonic forces on ocean chemistry during the Jurassic and Cretaceous Periods.

The course of evolution on Earth was altered by a series of severe environmental crises caused between 185 and 85 million years ago in the oceans, according to scientists.

The oxygen depletion led to major biological changes – including mass extinction of marine species – according to the researchers from the University of Southampton. The researchers combined statistical analysis and used computer models to understand how the chemical cycles in oceans would have responded positively to the breakup of theAccording to the researchers, this volcanic activity played a key role in shaping the course of the planet.

However, this increased biological activity also caused huge organic matter sinking into the ocean floor, and consumption of large amounts of oxygen, according to co-author Benjamin Mills, a Professor of Earth System Evolution at the University of Leeds.
