Where: Kane County, Utah (37.7° N, 111.4° W: paleocoordinates 45.6° N, 82.5° W)
• coordinate estimated from map
When: Middle Member (Kaiparowits Formation), Late/Upper Campanian (83.5 - 70.6 Ma)
• lower portion of the middle unit of the upper Campanian Kaiparowits Formation. The stratigraphic position of this site is approximately 190 m from the base of the formation (Roberts et al., 2013: fig. 6.3) and within approximately one meter stratigraphic proximity of bentonite ash bed KP-07, which has produced a U-Pb zircon age of 76.26 ± 0.10 Ma (Roberts et al., 2013), providing a precise age constraint for Akainacephalus johnsoni.
• bed-level stratigraphic resolution
Environment/lithology: crevasse splay; sandstone
Size classes: macrofossils, mesofossils
Collection methods: quarrying,
