Abstract
The number of late Neogene Spanish micromammal-containing continental sections with a correlation to the Geomagnetic Time Scale is steadily growing. Nonetheless, well-calibrated sections with dense micromammal records are still rare, biostratigraphic correlations between basins are not straightforward, and ages of uncalibrated sites are poorly constrained. Here, we aim at improving

the chronology of Iberian micromammal sections and sites for the interval 8.5–2 Ma by: (i) analyzing qualitative and quantitative similarities between rodent assemblages and turnover in the different basins, (ii) formulating a system of fifteen Iberian assemblage biozones, and (iii) constraining the ages of zone boundaries, assuming isochroneity across basins. Age uncertainty ranges for most known Iberian micromammal sites are obtained by combining regional biozone boundary ages with local magnetostratigraphic records, sedimentation rates and/or evolutionary rates. In addition, our results include new, integrated stratigraphic records from the Jumilla-La Celia and Teruel Basins, which are used to constrain the thus far poorly dated interval covering the latest Tortonian and earliest Messinian (8–7 Ma).

Note: Funding Information: We dedicate this paper to Hans de Bruijn, who sadly passed away in 2021. Hans was one of the founding fathers of micromammal paleontology and a principal initiator of systems of rodent-based biostratigraphy in Spain and many other areas. We thank Raef Minwer Barakat for allowing us to use his quantitative data for Guadix-Baza Basin rodents, Everett Lindsay for his information on the lithostratigraphy of sections in the Teruel Basin, and Plinio Montoya for his help in clarifying the stratigraphy of La Bullana. We thank Alexey Tesakov for sharing his insights on Dolomys and other arvicoline lineages. We acknowledge Karel Steensma for his invaluable help during the various field campaigns, and Lorenzo Vilas and Cayetano Herrero for discussions during field work in the La Celia area. Eduardo Espílez and Luis Mampel are thanked for taking rock samples for sedimentology, and João Trabucho, Jose Pedro Calvo and Ana Alonso for their help in characterizing the sedimentary paleoenvironment of the Las Pedrizas section, Anita van Leeuwen for carrying out XRD analyses at Utrecht University, Dolors Barsó for preparing the thin sections at the Faculty of Earth Sciences at University of Barcelona, and Jasper Huijsmans for his assistance with microscopy.
