Stratigraphy
Formation:Tecopa Lake Beds
Stratigraphic resolution:member
Stratigraphy comments: "from several stratigraphic levels... a few meters below the Huckleberry Ridge Tuff (2.1 Ma)" and therefore late Blancan instead of Illinoian, as thought by Jefferson 1991; the date is 2.103 +/- 0.019 Ma (laser fusion Ar/Ar) and derives from Honey et al. 1998 (Whistler and Webb 2005)
Lithology and environment
Primary lithology:gypsiferous mudstone
Lithology description: "a variety of gypsiferous mudstones, siltstones, and tufa (subaerial and freshwater limestone), with basin marginal deposits of sandstone and conglomerate"; fossils are from a "lake mud" also called an "unctuous... deep clay mire" (Whistler and Webb 2005)
Environment:lacustrine indet.
Geology comments: "Deposits comprise a series of lacustrine and marginal fluviatile deposits" (Whistler and Webb 2005)
Taphonomy
Modes of preservation:body
Collection methods and comments
Reason for describing collection:general faunal/floral analysis
