Collection methods and comments

Reason for describing collection:

biostratigraphic analysis

Taxonomic list comments:this is Prothero's "B2" list, which I assign to Wagonhound Section based on section of Peterson quoted by Osborn, and on later section of Riggs 1912, which suggest that most early AMNH, Princeton, and CM collections from "White River," "eastern end of Uinta Basin," etc. are from the upper part of Wagonhound Canyon between Bonanza and Kennedy's Hole, all of which are to the west of Coyote Basin and considerably to the east of White River Pocket (see)
the following records are strictly Uinta C according to Prothero or others but placed here by Kay 1957 or others:
likely to include any of the following "Wagonhound member" records of Kay 1957 and "B" records of others: Thisbemys ("Paramys") medius (strictly Uinta C: Wood 1962) "Ischyrotomus gidleyi" (synonym of Reithroparamys sciuroides; type is said by Wood 1962 and Black and Sutton 1984 to be from the Myton Mbr.) Leptotomus leptodus Wood 1962: "Wagonhound member... White River"; includes type of "Paramys grangeri" of Matthew 1910b Bunomeryx elegans
the following "Wagonhound" or "Uinta B" records are problematic for other reasons: Mytonomys mytonensis Korth 1988b (not mentioned by Prothero) "diacodont" Achaenodon insolens Peterson 1919: Douglass material from "Horizon B" (= Uinta B2), locality not given (species not recognized by Prothero)
"Oxyaenodon wortmani": probably type of Van Valen 1966, a nomen dubium AMNH specimen from "Uinta B"

"Isectolophus annectens" may be supposed Uinta C material of Peterson 1919 from "White River" or "Homogalax uintensis" type of Troxell 1922b from "mouth of the White River, Utah"
