Cerro de los Batallones

Nearly the entire proportion of fossils of Batallones-1 were of Carnivorans. The species of sabre-tooth cat known as Promegantereon ogygia and Machairodus aphanistus (the first complete skull) were found at B-1, as was Simocyon a type of red panda. In regards to the saber-tooth cats, Batallones-1 represents an ideal site for recording the percentage of specimens for which breakage of the upper canines occurred. Promegantereon, Machairodus and Paramachaerodus are perfect examples of this at Batallones; fossils indicate a high number of canine breaks from where the teeth hit the bones of a struggling victim, indicating these early machairodonts would use their elongated teeth to subdue prey as modern big cats do. A new species of Hispanomys (Rodentia) was found at various sites. ==Fauna==
