Geography comments: "at Renjiagou, Lingtai, Gansu Province" (Lingtai is a county: coordinate estimated from the location of Renjiagou)
said to be Late Pliocene and lower MN16: MN16 spans the Pliocene-Pleistocene boundary but is mostly Pliocene
Fig. 2 indicates that the fossils are from just above the 200 m level in the section, which is in a short normal polarity zone correlated with the base of the Gauss and said to be "3.4 ~ 3.5Ma"
this is chron C2An.3n, dated at 3.596 to 3.330 Ma by Ogg (2020)
