[1][2][3] Nine sites have been discovered with predominantly vertebrate fossils, invertebrates and plants being less represented.
[4] The species of sabre-tooth cat known as Promegantereon ogygia and Machairodus aphanistus (the first complete skull)[5] were found at B-1,[6] as was Simocyon a type of red panda.
[7] 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.
