PBDB Collection

Wahweap Wash, UT (U1-21) (Cretaceous of the United States)

Where: Kane County, Utah (37.1° N, 111.6° W)

• Paleocoordinates: 44.3° N, 70.2° W (Wright 2013)

• small collection-level geographic resolution

When: Neocardioceras Ammonite zone, Tropic Shale Formation, Late/Upper Cenomanian (100.5 - 93.9 Ma)

• Bed horizon is the sample number not the lithologic unit number. The lithologic unit numbers that correspond to the sample numbers given can be found in reference for collection (Elder, 87).

• bed-level stratigraphic resolution

Environment/lithology: marine; lithified, gray, green, calcareous shale

• Shale, mod. indurated, mod. laminar.

Note: Section U1 constitutes interbedded limestones and shales, but this sedimentary structure is not reflected in the descriptions of each collection, as each is often a single bed, or a portion thereof.

Size class: macrofossils

Collection methods: bulk, mechanical,

• Bulk sample disaggregated in lab.
