Most paleontologists recognize five major ones, End-Ordovician, Late Devonian, Late Permian, Late Triassic, and Cretaceous-Tertiary (KT- the "dinosaur killer"). Extinction rates and habitat destruction appear to be increasing over the last 10,000 years leading some scholars to propose the present day as a "sixth extinction".
