Uinta Protylopus Quarry
Kommentar z. Taxonomie
according to Burke 1934b, Myton Pocket was not discovered until 1912, so earlier Uinta C records cannot belong to it
Kay's list is for all of Uinta C; I have removed records not tied to Myton Pocket by revised list of Prothero 1996a or other sources
Black and Sutton also list "Leptotomus grangeri"
Myton Pocket is 7 mi. E of Myton, Duchesne Co. (often said to be 6 mi E or SE of Myton) and is close to the base of Uinta C
Protylopus Quarry is within Myton Pocket
"Uintatherium sp." of Kay is probably erroneous, see Wheeler 1961

"Hyrachyus sp." could be Triplopus sensu Radinsky 1967a and no specimens are discussed in the literature

"Mesamynodon medius" of Kay is of unclear status because no material of this species or its sometime synonym "Hyracodon primus" has ever been attributed to the Uinta Fm. sensu stricto

"Hylomeryx simplicidens" of Kay appears to be a nomen nudum

"Achaenodon sp." is listed by Kay, but no other publication suggests that this genus is present above Uinta B

"Simimeryx minutus" is listed by Kay, but no specimen other than the type from Red Narrows is discussed in the literature

Atwater et al. 2020: The maximum depositional age calculated for the Purple Bench locality (43.5 – 44.5 Ma) constrains the absolute age of the late Uintan NALMA (Ui3) within the Tornillo Basin. TMM overlies Whistler Squat and underlies Cotter and Skyline Channels
