Eberth and Kamo, 2019: Combined with age data for the K-Pg boundary and a calibrated age-range for magnetochron 30n, our age for the Battle bentonite allows us to assess a maximum age of ~66.88 Ma for the base of the overlying Scollard Formation, and an age range of ~66.88–66.04 Ma for the K-ScF (the Cretaceous portion of the Scollard Formation).
