In the fossil record such tracer events are usually keyed to disappearance (extinction) of a widely distributed and rapidly changing species or the appearance of such a species in the geological record. Chronozones [and] chrons are used especially in the various disciplines related to Geology, notably in stratigraphy where relative dating is employed. 2, record 1, English, - chron
