Reorganization of the Biosphere After the Triassic-Jurassic Mass Extinction

The Triassic-Jurassic extinction event affected the modern fauna more severely than any other. Massive CO2 injection into the exosphere via the Central Atlantic Magmatic Province is considered the most likely trigger for extinction. Reefs and carbonate faunas were devastated, making the event a candidate for ocean acidification in the rock record. Furthermore, benthic marine ecosystems were completely reorganized after the extinction in ways that offer insight into future ecosystem changes.
