摘要

Vallesian (early Late Miocene) strata from the recently introduced Ca˜nada section (provinceudof Zaragoza, east Central Spain) have yielded fairly large insectivore assemblages. Theseudshow that, after the generally dry Aragonian, the Vallesian gave rise to more humid conditionsudthat were favourable to insectivores, both in number of taxa, and in overall number ofudspecimens. The assemblage of Ca˜nada 8 (Biozone H) is dominated by shrews, whereas theudassemblage of Ca˜nada 10 (uppermost Biozone H) contains the oldest record of Desmanella inudthe area. This seems to signify a bioevent in which after millions of years of absence, talpidsudreturn to the area. In addition to the Vallesian assemblages, a small Turolian insectivoreudfauna has been recovered. On the basis of the rodents, Ca˜nada 12 was assigned to BiozoneudL, and the insectivore assemblage is very similar to the assemblages from the Teruel basinudof that zone. This implies that the discovery of Postpalerinaceus in Ca˜nada 12 is the youngestudpublished record of this large spiny hedgehog.
