New material of Carnivora (Mammalia) from the Late Miocene of Axios Valley, Macedonia, Greece

Abstract

A new collection of carnivores from the Late Miocene deposits of Axios Valley, Macedonia, Greece was collected in 2004–2009 at the localities named Xirochori 1 (XIR) and Ravin de la Pluie (RPl), dated to the Late Vallesian (MN 10), as well as at Ravin des Zouaves 5 (RZO), dated to the Early Turolian (MN 11). The studied material is described and compared morphologically and biometrically with other materials from Greece and its neighboring area. The following species are determined: XIR: Dinocrocuta sp.; RPl: Eomellivora wimani, Adcrocuta eximia leptoryncha, ?Hyaenictis sp., Metailurus parvulus; RZO: Plioviverrops orbignyi, Machairodus giganteus. This collection is interesting because it includes the upper deciduous dentition of A. eximia and Dinocrocuta, which are only known from limited material until now, especially the latter taxon. E. wimani is recognized for the first time in Greece and the Balkans, while M. parvulus is identified for the first time in the Vallesian of Greece. The possible presence of Hyaenictis in RPl is the first indication of its presence in the Vallesian. The guild structure diagrams of the carnivore fauna from the three studied localities provide some indications of their palaeoenvironment, which fits quite well with the results of previous studies on the palaeoenvironments of these localities and of the wider Eastern Mediterranean region.
