Stratigraphic resolution: | formation | ||||
Stratigraphy comments: "Tephrochronology and Ar/Ar dates indicate the Thousand Creek Formation was deposited between ~8.3-7.0 Ma (Perkins et al. 1998). However, this age conflicts with the radiometric age for the capping basalt, dated to ~9 Ma (Green 1984)." (Prothero & Davis 2008) |
Lithology and environment
Primary lithology: | not reported |
Environment: | terrestrial indet. |
Taphonomy
Modes of preservation: | body |
Size of fossils: | macrofossils,mesofossils |
Collection methods and comments
Reason for describing collection: | general faunal/floral analysis |
Taxonomic list comments:earlier list given by Merriam 1917 and augmented by Merriam and Stock 1928 ash near top of section correlated geochemically with the Rattlesnake Tuff, which overlies the Rattlesnake fauna (see), by Perkins et al. 1998 Munthe 1988 mentions a questionable record of "Tomarctus kelloggi" at Thousand Creek that is actually T. sp.; this may be Stirton's indeterminate canid |
