On the new age estimate for the Venta del Moro locality
During the final stages of writing this manuscript, a new paleomagnetic calibration for
the locality of Venta del Moro was published by Gibert et al. (June 2013). These authors
indicated that Venta del Moro locality lies in chron C3An.1n and suggested an age of
6.23 Ma, based on the sediment accumulation rates. For our study, we used the
previously estimated age of 5.9 Ma in chron C3r (Opdyke et al. 1997). After ordination
by the ML AEO method, the locality had an estimate age of 5.75 Ma. Examination of
the species present in Venta del Moro and, therefore, subject to possible changes in their
temporal ranges suggests that no major changes in the results of our analyses are
expected with the new calibration. Most species from Venta del Moro were present in
older and younger fossil sites (e.g., Anancus arvernensis, Lartetotherium
schleiermacheri, or the African immigrant Hexaprotodon crusafonti), so neither their
OFAs/IFAs and OLAs/ILAs would have undergone major changes. Some other Venta
del Moro species are singletons (e.g., Thalassictis hyaenoides, Paramachaerodus
maximiliani, Eucyon debonisi, Tragoportax ventiensis, Parabos soriae, Paracamelus
aguirrei), which were omitted from the calculations of the diversity metrics and the
ecological structure metrics. The study of Gibert et al. (2013) corroborate that the
dispersal of mammals from Africa to southwestern Europe and vice versa was
underway before the complete isolation of the Mediterranean Basin in the lastest
Miocene. However, we acknowledge that this new age estimate must be incorporated
into future research.
