The past 500 million years of Earth's history were marked by episodes of mass extinction and other extreme environmental changes that coincided with periods of major volcanic eruptions, bolide impacts, and other uncertain events. Records based on proxy data and other approaches have demonstrated a causal relationship between environmental and geologic or extraterrestrial events. However, our understanding of the wider context and nature of environmental changes before, during, and after these events remains incomplete. This session invites contributions presenting the latest research advances on the end-Ordovician, Late and end-Devonian, end-Permian, end-Triassic, end-Cretaceous, and other periods of biotic crisis and/or global climate, such as Oceanic Anoxic Events or the Paleocene-Eocene Thermal Maximum. The session aims to bring together researchers from geological, geochemical, geophysical, and biological disciplines to improve our understanding of the cause-effect scenario of the five major mass extinction events as well as other lesser-known events of environmental and climatic crisis
