Stratigraphic model of Belly River Group proposed by Eberth and Hamblin (1993). (A) In this model, the Oldman–Dinosaur Park discontinuity is diachronous across its expanse, expressing up to 1.5 m.y. of diachroneity between Dinosaur Provincial Park (DPP) and the Onefour (Of) region in southern Alberta (legacy 40Ar/39Ar ages are from Eberth and Hamblin [1993], updated with 2σ errors). (B) Two distinct clastic lobes of alluvial nature fill the basin, with the Dinosaur Park lobe (DP lobe) sourced to the north, and the Oldman lobe (O lobe) sourced to the south. The diachronous discontinuity is interpreted to have developed at the intersection of the two alluvial lobes and is argued to maintain distinction across the region. The Omineca belt is identified as a source terrane for clastics in the basin and likely yielded the extraformational clasts in the Dinosaur Park Formation. (C) Over time, the Dinosaur Park lobe overtopped the Oldman lobe as it built southward and eastward into the basin. Both units are interpreted to have accumulated during R8 (Claggett regression) and T9 (Bearpaw transgression). Arrows in B and C indicate general paleocurrent directions. Figure is modified from Eberth and Hamblin (1993).

Belly River Group exposures in Dinosaur Provincial Park, Alberta. (A) View of contact between Oldman (OF) and Dinosaur Park (DPF) Formations. Here, the contact (dashed line) is placed at the erosive base of a fluvial paleochannel. (B) Another view of contact between Oldman (OF) and Dinosaur Park (DPF) Formations at the field station. Here, the contact is approximated based on lithological changes as reflected in color and weathering in outcrop. Note change in slope that coincides with approximate formation boundary (dashed line).

Belly River Group stratigraphy at Dinosaur Provincial Park based on outcrop and subsurface data as described by Eberth (2005). Magnetostratigraphy from Lerbekmo (2005). Gamma log is from the Princess Well (Alberta Research Council Core Hole 83-1). Composite outcrop section (right) was measured in the Iddesleigh area by DAE (23–24 July 1996; see Fig. 1). With the exception of BB and LCZB, which were observed in the measured section, bentonite placements are inferred using a variety of marker beds and surfaces shown here. Inset explains symbols and abbreviations used in the measured section. Bentonite abbreviations as in Fig. 1 and explained in the text.
