Resumen:
|
The micromammal sequence of the Calatayud-Montalbán Basin in Northeast Central Spain is exceptional in terms of its faunal richness and dating accuracy. However, until now, several classical localities with ages close to the Middle to Late Miocene transition have never been directly tied to the Geomagnetic Polarity Time Scale. Here, we present an updated stratigraphic framework for the Daroca area, resulting in new and better-constrained ages for the micro- and macromammal-bearing sites of Toril, Carrilanga, and Pedregueras, and the macromammal site Los Andurriales. Toril is correlated to chron C5Ar.1r with an age of 12.7 Ma. Carrilanga and Los Andurriales are dated at 11.3 Ma, slightly older than the nearby sites Nombrevilla 9–10 (11.2 Ma). The fauna of these latter sites just pre-dates the entry of Hipparion, which is supposed to have its first appearance in Europe also at 11.2 Ma. The age of Pedregueras 2A is estimated at 10.6 Ma, constraining the local Zone H–I boundary and the first Iberian occurrence of Cricetulodon to 10.7 or 10.6 Ma. With an age of 10.4 Ma, the site of Pedregueras 2C is documenting the presence of very rare Murinae in Europe long (ca. half a million years) before their attainment of general dominance.
