Bullet-Points Abstract
- Democricetodon and Megacricetodon species are present during the early Miocene in the Vallès-Penedès Basin.
- The first occurrence of both genera Democricetodon and Megacricetodon in the Basin mark the beginning of the MN4.
- These species are key for stablish a high-resolution local biozonation and correlated to other European Basins.
Keywords: early Miocene; Democricetodon; Megacricetodon; Biostratigraphy; Iberian Peninsula.
