Collection methods and comments
Reason for describing collection: | biostratigraphic analysis |
Taxonomic list comments:some material from Wyoming may be included formation-level composite list; some records may pertain to localities south of Pine Ridge sensu stricto (e.g., Zodiolestes) Harrison Fm. dated at 21.3 (= 21.86) Ma by Evernden et al. 1964 (KA 481); seems unreliable based on K content and percent atmospheric Ar "devil's corkscrews" occur no higher than this level but as far down as the Monroe Creek Fm.: Hunt 1985a beaver material reported by Martin 1987 comes from KUVP locs. 26 (Ellicott), 31, 91 (Breuger Ranch), and 115 "Cyclopidius densa" Schlaikjer 1935b: "lower Harrison southwest of Chadron"; this is said to be "Lower Miocene" by Loomis 1925 and Schlaikjer's attribution is of uncertain significance "Promerycochoerus sp." listed by Hunt 1985a for Eagle Crag, but omitted by Tedford et al. 1987 |
