• coordinate based on political unit

• outcrop-level geographic resolution

When: Himes Member (Cloverly Formation), Middle Albian to Middle Albian (109.0 - 93.5 Ma)

• Unit VII

•

•D'Emic et al. 2019: New data reported in this study suggest that deposition of the Cloverly Formation spanned the Valanginian–Cenomanian stages (ca. 140 Ma–98 Ma), a longer time interval than the commonly cited Aptian–Albian depositional timeframe. In the mid–late Albian to early Cenomanian (ca. 109–98 Ma), sediment sourced from the east was deposited as the Himes Member and Greybull Sandstone.

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; concretionary lithology not reported
