dc.description.abstractThe Jurassic Windy Hill Sandstone in Wyoming contains features consistent with deposition on an open-coast tidal flat, like those along the coast of Korea today, and this study uses field and UAV-based methods to investigate the sequence stratigraphic context of these deposits. Surfaces of forced regression are present and indicate deposition in the FSST and LST, re-enforcing the idea that tidal deposition can occur in many contexts. The recognition of surfaces of forced regression at stratigraphic positions previously interpreted as the J5 unconformity suggest that this surface may be at a stratigraphically higher position, implying that portions of the Redwater Shale, Windy Hill Sandstone, and Morrison Formation are contemporaneous in Wyoming. The Morrison Formation displays continuous progradation that is attributed to a slowed rate of tectonic subsidence, illustrating how tectonics can result in deviations from predicted sequence stratigraphic architecture, with the TST apparently absent from the rock record
