Where: Idaho (46.5° N, 116.8° W: paleocoordinates 46.4° N, 111.8° W)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Latah Formation, Langhian (16.0 - 13.8 Ma)
• Latah Formation overlies the Grande Ronde basalts (16-15.5 Ma; Barry et al., 2013), although younger parts of the Grande Ronde are absent at some localiies (Nash & Perkins, 2012). It underlies the Saddle Mountain basalts (c. 15 Ma and younger; Barry et al., 2013). Ash beds within the Latah Formation at White Bird, Idaho, are dated to 15.77 Ma (Mascall Tuff), 15.66 Ma (Bully Creek tuff), and an interpolated age of 14.3 Ma (Nash & Perkins, 2012).
• group of beds-level stratigraphic resolution
Environment/lithology: lacustrine - small; lithified mudstone
Size class: macrofossils
Preservation: mold/impression
Collected by S.E. Lewis in 1966; reposited in the UCM
• At least the Megachiline bee is deposited in University of Colorado Museum.
