111 Ranch

Age. Late early Blancan and late Blancan, an interval from ca. 2.4 to 3.0 Mya. The lower ca. 30 m appears to be late early Blancan (about 2.4-2.7 my) (Morgan and White 2005), with the Pleistocene late Blancan above that level.

General Description. About 100 m of fossiliferous fluvial and lacustrine sediments (Morgan and White 2005).

Discussion. Judging from the data given in Galusha, et al. (1984), virtually all taxa (with the exception of Hemiauchenia blancoensis) listed by Galusha et al. and Morgan and White (2005) occurred within the Pleistocene late Blancan. It is unclear where the Grus americana specimen came from stratigraphically.
