MN zonation
The MN zonation is a system used to correlate mammal-bearing fossil localities in the Miocene and Pliocene epochs of Europe. It consists of sixteen consecutive zones (numbered MN 1 through MN 17; MN 7 and 8 have been joined into MN 7/8) defined through reference faunas, well-known sites that other localities can be correlated with.

The zones are as follows:[1]
| Interval | Start | End | Age |
|---|---|---|---|
| MN 1 | 23.8 Ma | 22.4 Ma | Aquitanian, Agenian |
| MN 2 | 22.4 Ma | 20.0 Ma | |
| MN 3 | 20.0 | 16.9 Ma (between 16.6 and 17.2 Ma) | |
| MN 4 | 16.9 Ma (between 16.6 and 17.2 Ma) | 16.0 Ma | |
| MN 5 | 16.0 Ma | 13.7 Ma | |
| MN 6 | 13.7 Ma | 12.75 Ma (between 13 and 12.5 Ma) | |
| MN 7/8 | 12.75 Ma (between 13 and 12.5 Ma) | 11.1 Ma | |
| MN 9 | 11.1 Ma | 9.7 Ma | |
| MN 10 | 9.7 Ma | 8.7 Ma | |
| MN 11 | 8.7 Ma | 7.75 Ma (between 8.0 and 7.5 Ma) | |
| MN 12 | 7.75 Ma (between 8.0 and 7.5 Ma) | 7.0 (between 6.8 and 7.2 Ma) | |
| MN 13 | 7.0 (between 6.8 and 7.2 Ma) | 4.9 Ma | |
