25 de jun. de 2015 · Un grupo multidisciplinar de investigadores ha descrito los primeros fósiles craneales de una especie de depredador carnívoro, Eomellivora piveteaui, de hace nueve millones de años. La especie tenía el tamaño de un pastor alemán y era capaz de enfrentarse a los grandes tigres dientes de sable.
Eomellivora piveteaui, una especie que se describió por primera vez en 1965 a partir de restos muy fragmentados, era un animal carnívoro y voraz. Su capacidad de romper huesos lo convertía en un depredador muy versátil y activo de la fauna del Mioceno Superior.
Eomellivora is an extinct genus of prehistoric mustelids, closely related to the honey badger, known from Eurasia and North America, and tentatively Africa. It was one of the biggest mustelids ever known, bigger and more hypercarnivorous than the modern wolverine.
The Eomellivora dentition of Batallones-3 is similar in size to that of E. wimani and E. piveteaui. It is comparable to E. piveteaui in the absence of posterior accessory cusp p2, and anterior accessory cusp in p3; both species present the same robustness in p4, m1, P4 and M1, as well as a similar morphology in P4 and M1.
27 de may. de 2015 · Eomellivora piveteaui was specialized for a more hypercarnivorous diet than the largest extant terrestrial mustelids, although it also had some derived bone-crushing adaptations.
27 de may. de 2015 · We describe cranial, mandibular, and dental remains of five individuals of the giant mustelid Eomellivora piveteaui Ozansoy, 1965, from the late Miocene (MN10) site of Cerro de los Batallones (Madrid, Spain)—the first complete cranial remains recorded for this species and the most complete remains of the genus.
Eomellivora piveteaui was a large mustelid adapted to a more hypercarnivorous diet than the largest extant terrestrial mustelids (e.g., G. gulo and M. capensis), and the other species of Eomellivora and also shows some bone-crushing or carcass-processing adaptations.
