Restructuring in benthic level-bottom shallow marine communities due to prolonged environmental stress following the end-Permian mass extinction

Because the end-Permian mass extinction was the largest mass extinction since the Cambrian, numerous studies have focused on taxonomic changes and patterns immediately before and after the Permian/Triassic boundary. This synthesis of paleoecological data demonstrates that the end-Permian mass extinction and the Early Triassic aftermath were ecologically, as well as taxonomically, significant events in the history of life. A variety of short-term and long-term structural changes in ecosystems and paleocommunities were facilitated by deleterious environmental conditions that persisted through the Early Triassic.
