In Fariña et al. (2014), we claimed that a rich fossiliferous locality, Arroyo del Vizcaíno (hereafter, AdV), with marked bones that are much older than widely accepted for human presence in the Americas, deserved ‘to be included in the agenda of early American peopling, either as a not foreseeable discovery … or as an example of natural processes mimicking human presence’. The comments by Suárez et al. (2014) fail to offer a hypothesis of such a process. Instead, they mention we incur in ‘serious methodological problems and important interpretative errors’ that remain mostly unexplained.
