Stratigraphy
Geological group:Princeton Formation:Allenby Member:Vermillion Bluffs shale
Stratigraphy comments: Two fossiliferous areas are listed as Burke Museum of Natural History and Culture, University of Washington localities UWBM B3263 (upper level) and UWBM B4294 (lower
level), and correspond to mapped megafossil localities in the Allenby Formation for this area on geological maps for south and west of Princeton (Read 1987, 2000; Massey et al. 2010). The smaller, lower site occurs immediately above the Tulameen River with beds that are nearly horizontal, in contrast to the upper, larger site, approximately 50mhigher (UWBM B3263), which consists of a small anticline that was exposed during road construction.
Lithology and environment
Primary lithology:planar lamination lithified "shale"
Lithology description: Fossils occur in a shaley tan to buff-colored matrix that can weather to produce a thin, paper shale-like matrix, whereas less weathered areas contain a thicker mudstone. Thomas Ranch (Mustoe locality P11) is indicated as clastic in composition. The shale of the upper locality (UWBM B3263) was deformed through intense folding such that complete examples of any of the larger leaves are extremely rare. Cuticle was not apparent on most specimens
Environment:lacustrine - small
Taphonomy
Modes of preservation:adpression
Lagerst�tten type:conservation
Size of fossils:macrofossils,mesofossils,microfossils
Collection methods and comments
Reason for describing collection:general faunal/floral analysis
