The research team, which includes Assistant Professor Sarah Carmichael, is examining the relationship between climate change and changes in the ecosystems in the Devonian period, from 419 to 359 million years ago. This is the third most significant mass extinction and it was caused by plants, Waters said. Unlike the dinosaur mass extinction, which was related to an asteroid impact, this one was environmentally related.. In the Devonian period, Waters explained, the world was experiencing super greenhouse climate conditions.
