Where: Santa Fe County, New Mexico (35.1° N, 106.1° W: paleocoordinates 35.7° N, 103.1° W)

• coordinate estimated from map

When: Skull Ridge Member (Tesuque Formation), Barstovian (16.0 - 13.6 Ma)

• Magnetostratigraphy and ash dating have shown the Skull Ridge Member to span between 16.0 and 14.9 Ma (Barghoorn, 1981; Tedford and Barghoorn, 1993; Berggren et al., 1995) and sanidine 40Ar/39Ar dates of 15.42 ± 0.06 Ma (McIntosh and Quade, 1995) and 15.3 ± 0.05 Ma were obtained from the White Ash Number 4 near the top of the Skull Ridge Member (Tedford et al., 2004)
