Jaramillo-aged carnivorans from Collecurti (Colfiorito Basin, Italy)

Late Early Pleistocene vertebrate assemblages in the Mediterranean area have sparked the interest of the scientific community in the last two decades mainly thanks to the discovery of fossils and/or stone tools testifying to the presence of early Homo. However, our knowledge of most of these assemblages is biased by the lack of well-constrained chronological data, especially for those close to or related to the Jaramillo magnetostratigraphic subchron (ca. 1.0 Ma). As a matter of fact, the available European palaeontological assemblages chronologically close to the Jaramillo interval are overall scarce, especially for the period prior to the so-called '0.9 Ma event'. This long and cold glacial period was characterised by profound changes in ecosystems and important faunal turnover in Europe, including the replacement of most Villafranchian species by typical Galerian ones. Here, we report on the carnivoran remains from Collecurti (central Italy), that is, one of the few available Jaramillo-dated assemblages in Europe. The Collecurti sample includes the species Canis (Xenocyon) lycaonoides, Canis mosbachensis, and Ursus deningeri and is here described in detail for the first time and compared with those from similar-aged European sites.
