There’s a lot in this paper. But our main finding is that while marine ecosystems returned to ecological stability by the Sinemurian, terrestrial ecosystems were in a prolonged state of ecological flux and turnover well into the Aalenian. Why is this?

We are by no means the first to suggest that the ETE was more severe on land in the oceans, but these new findings suggest that it was likely because low taxonomic redundancy in functional groups leads to severe ecological instabilities.
