Kutz Canyon (Nine UALP Locs) (Paleocene of the United States)

Also known as UALP 75106 (Taylor Mound), 75140, 7640 (Larry's Beaucoup), 7641, 7643, 7644, 7660, 7662, 7778

Where: San Juan County, New Mexico (36.3° N, 108.2° W: paleocoordinates 42.9° N, 88.3° W)

• coordinate based on political unit

• small collection-level geographic resolution

When: Nacimiento Formation, Torrejonian (63.8 - 60.9 Ma)

• not far below the middle of a reversed magnetic polarity zone in the Kutz Canyon section interpreted as C27r based on the position of the K-T boundary in the correlative Barrel Spring Arroyo = De-na-zin Wash section: see Butler et al. 1977, Lucas et al. 1997

Environment/lithology: terrestrial
