• Díaz-Sibaja et al. 2020: The Valsequillo Quaternary deposits overlay Cretaceous rocks of the Balsas group. The Pleistocene sediments comprises 70–100 m in four major units: the Amomoloc lake beds (also termed Lower Lake beds), the Xalnene tuff, the Atoyatenco lake beds (also named Upper Lake beds, which contained the Batan Lahar, sometimes referred as a distinctive unit), and the Valsequillo gravels at the top (Stevens et al., 2012; Metcalfe et al., 2016).

•A radiocarbon age of 7151 +/- 70 years BP for CRINAHP-1648 calvarium was obtained. This age places this specimen at the Middle Holocene, within the Northgrippian Stage, and within the Santarosean North American Land Mammal Age (NALMA) (Barnosky et al., 2014).
