Also known as NMMNH 1226, 2513, 2543, 2544, 2545, 2546, 2547, 2548, 2549; Sinclair and Granger Loc. 1
Where: San Juan County, New Mexico (36.3° N, 108.2° W: paleocoordinates 42.9° N, 88.3° W)
• coordinate based on political unit
When: Nacimiento Formation, Torrejonian (63.3 - 61.7 Ma)
• low in a reversed magnetic polarity zone correlated with the Barrel Spring Arroyo = De-na-zin Wash section interpreted as C28r based on the position of the K-T boundary in that section: see Butler et al. 1977, Lucas et al. 1997
Environment/lithology: terrestrial; lithology not reported
Size classes: macrofossils, mesofossils

Taxonomic list
identical to list 10 of Williamson 1996
list of Williamson and Lucas 1997 repeats a subset of earlier list
I suspect this is on the divide between Gallegos Canyon and De-Na-Zin wash because it is referred to by both names by Williamson 1996
just above part of local section of known paleomag polarity
omits multis
