The Triassic was a time of major biological changes in the ocean and on land, with the appearance of many groups of animals and plants that formed new, modern-style ecosystems. Three major events appear to have prompted the formation of new ecosystems, whereby mass extinctions emptied ecological niches, i.e., the Permo–Triassic mass extinction (PTME), the Carnian Pluvial Episode (CPE) and the end-Triassic mass extinction (ETME). These events have been all attributed to the emplacement of Large Igneous Provinces (LIPs), i.e., the Siberian Traps (STLIP; ca. 252 Ma), the Wrangellia (ca. 230 Ma) and the Central Atlantic Magmatic Province (CAMP; ca. 201 Ma), respectively. Such link highlights the role of enormous volcanic events in changing global climate and environments, and causing profound biodiversity loss, but also in driving the rise to the ascendancy of new groups of animals and plants, the appearance of evolutionary innovations and biological traits, and the construction of new marine and terrestrial ecosystems.

This Research Topic of Frontiers in Earth Science aims at gathering an open access article collection of original, cutting-edge research studies and reviews on the biological turnovers and LIP eruptions that marked the latest Permian – earliest Jurassic interval, with particular emphasis on the emergence of new marine and terrestrial ecosystems in the Triassic, and the role of LIPs in determine the direction of Mesozoic evolution.

We welcome articles on all areas studying the biotic and environmental evolution during the Triassic, i.e., paleontology and paleobotany, sedimentology, stratigraphy, geochemistry, petrology, volcanology, as well as biogeochemical and climate modelling, and in particular interdisciplinary studies aiming at unveiling the links between volcanism and biological changes. We encourage papers focusing on the single mass extinction and LIP events (e.g., patterns of extinction and recovery, selectivity and survival strategies during the PTME, CPE and ETME; timing and style of STLIP, Wrangellia and CAMP emplacement; high-resolution geochemical records; post-extinction diversifications), but also on long-term paleoclimatic, paleoenvironmental and paleontological changes (e.g., biodiversity and geochemical studies through the entire Triassic, or parts of it; modelling of long-term environmental, climatic and ecological changes). We particularly encourage authors to submit new, provocative and sound theories and models that shed new lights on our understanding of Triassic biological changes and LIP volcanism.
