Mammal Paleogene zones
The Mammal Paleogene zones or MP zones are a system of biostratigraphic biozones in the stratigraphic record used to correlate mammal-bearing fossil localities of the Paleogene period of Europe. It consists of thirty consecutive zones (numbered MP 1 through MP 30; MN 8 and 9 have been joined into MN 8 + 9 zone; and MP 17 zone is split into two zones – MP 17A and MP 17B zone) defined through reference faunas, well-known sites that other localities can be correlated with.
