Calabrian stage

Common card · No. 385318

Calabrian is a subdivision of the Pleistocene Epoch of the Quaternary period and the geologic time scale, defined as 1.8 Ma—774,000 years ago ± 5,000 years, a period of ~1.026 million years. The end of the stage is defined by the last magnetic pole reversal (781 ± 5 Ka) and plunge into an ice age and global drying possibly colder and drier than the late Miocene (Messinian) through early Pliocene (Zanclean) cold period. Originally the Calabrian was defined as a European faunal stage primarily based on mollusk fossils. It has become the second geologic age in the Early Pleistocene.
