The Mesozoic Era begins with the approximately 50-million-year-longTriassic Period, a major juncture in Earth history when thevast Pangaean supercontinent completed its assembly and beganits fragmentation, and the global biota diversified and modernizedafter the end-Permian mass extinction, the most extensive bioticdecimation of the Phanerozoic. The temporal ordering of geologicaland biotic events during Triassic time thus is critical to theinterpretation of some unique and pivotal events in Earth history.This temporal ordering is mostly based on the Triassic timescale,which has been developed and refined for nearly two centuries.This book reviews the state of the art of the Triassic timescaleand includes comprehensive analyses of Triassic radio-isotopicages, magnetostratigraphy, isotope-based and cyclostratigraphiccorrelations and timescale -relevant marine and non-marine biostratigraphy.
