Following the Permian-Triassic mass extinction (PTME) ∼252 million years ago (Ma), recovery of marine diversity was protracted over the ∼5 Myr of the Early Triassic, with complete rebuilding of marine ecosystems continuing for up to 50 Myr after the extinction event (Chen and Benton, 2012; Song et al., 2018).
