Time
| Period: | Cretaceous | Epoch: | Early Cretaceous |
| Stage: | Valanginian | 10 m.y. bin: | Cretaceous 1 |

Stratigraphy
| Geological group: | Dakota | Formation: | Cedar Mountain | Member: | Yellow Cat |
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: The age of the base of the YCM is unknown and estimates range from Berrisian to early Aptian. Britt et al. 2007 suggested a maximum depositional age for the YCM of ~124Ma, but Sames et al. 2010 suggested on the basis of ostracod biostratigraphy the YCM may be as old as Late Berrisian. Hendrix et al. 2015 and Joeckel et al. 2019 supported this with U-Pb dates from detrital zircons, the latter study suggested that the upper YCM is Valanginian. At any rate, the age of the overlying Poison strip member was dated at its base to 119.4Ma, so the YCM is older than this. | |||||
