Bioevent

In this article, we will fully explore the fascinating world of Bioevent and its impact on modern society. From its origin to its current evolution, we will analyze how Bioevent has influenced and transformed different aspects of our daily lives. Additionally, we will examine the various perspectives and opinions that exist around Bioevent, as well as its possible implications for the future. Throughout this writing, we will embark on a journey of discovery and reflection about Bioevent, with the aim of better understanding its relevance in today's world.

A bioevent or bio-event (a shortening of 'biotic event' or 'biological event') is an event recognised in a sequence of sedimentary rocks, where there is a significant change in the biota as recorded by assemblages of fossils over a relatively short period of time. It has been defined as "short-term (hours or days to kyrs) locally, regionally, or interregionally pervasive changes in the ecological, biogeographical, and/or evolutionary character of biotas that are isochronous or nearly so throughout their range". Bioevents either relate to diversification of a particular fossil group or a reduction, these may equate to speciation events or extinction events, or may only represent migration. Records of the appearance and disappearance of particular taxa at a single locality are insufficient to define a bioevent.
