Also known as UMNH VP Locs. 6, 62
Where: Iron County, Utah (37.7° N, 113.0° W: paleocoordinates 45.9° N, 83.5° W)
• coordinate based on political unit
• small collection-level geographic resolution
When: Iron Springs Formation, Late/Upper Santonian to Late/Upper Santonian (85.8 - 70.6 Ma)
• Age of Iron Springs Formation is poorly constrained. Eaton et al. (2014) obtained radiometric dates from the Iron Springs Formation. They reported an 40Ar/39Ar age of 83.1±1.1 Ma from a blue biotite ash found in Parowan Canyon, east of Parowan Gap. However, age may extend back to the latest Cenomanian (Goldstrand, 1990; Fillmore, 1991; Eaton et al. 2001)
• bed-level stratigraphic resolution
Environment/lithology: terrestrial; lithology not reported
Size class: mesofossils
Collection methods: bulk, sieve,
