"? Paradjidaumo sp.", NISP 4, is possibly reworked from underlying Chadronian deposits that yield P. hansonorum
"Heliscomys cf. tenuiceps" (NISP 5): compared to the florentiamyids Ecclesimus tenuiceps and Kirkomys schlaikjeri, but Korth et al. 1990 specifically state that no florentiamyids are present
