DMNH 4865 (Grand Staircase - Escalante National Monument) (Cretaceous of the United States)

Also known as Lutemys warreni type locality

Where: Kane County, Utah (37.3° N, 112.4° W: paleocoordinates 45.5° N, 83.8° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Kaiparowits Formation, Late/Upper Campanian (83.5 - 70.6 Ma)

• bed-level stratigraphic resolution

Environment/lithology: fluvial; gray, green siltstone

• The locality that yielded the specimen described herein (DMNH locality 4865) consists of

•green-gray siltstones deposited in a shallow overbank setting consistent with a perennial wetland environment. The locality is stratigraphically located in the lower to middle portion of the middle unit (Roberts et al., 2005), above a volcanic ash (bentonite) bed radiometrically dated to 75.97 § 0.18 Ma (40Ar/39AR) (Roberts et al., 2013) and presumably below an ash bed dated to 75.51 §0.15 Ma (40Ar/39AR) from the upper portion of the middle unit (Roberts et al., 2005, 2013). This coincides with the most fossiliferous interval within the Kaiparowits Formation from which most of the described vertebrate taxa have been recovered to date and closely overlaps with the fossiliferous interval of the Dinosaur Park Formation of southern Alberta (Roberts et al., 2013).
