Also known as Bryce Canyon NP

Where: Utah (37.6° N, 112.1° W: paleocoordinates 45.7° N, 83.3° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Wahweap Formation, Middle Campanian (83.5 - 70.6 Ma)

• "approximately Aquilan"

•

•Jinnah et al. 2009: The ash horizon, located ~40 m above the base of the Wahweap Formation, yields an age of 80.1 +/- 0.3 Ma. The new radiometric data improve upon previous biostratigraphic age estimates for the Wahweap Formation and indicate that the formation was deposited between approximately 81 and 76 Ma. The youngest population of detrital zircons from the base of the Wahweap Formation clusters around 83–82 Ma, while the youngest population in the capping sandstone near the top of the formation is between 77–81 Ma, consistent with the 40Ar-39Ar age.

• bed-level stratigraphic resolution
