Taxonomic list
• said to be "medial Arikareean"
"Upper Cabbage Patch" list of Rasmussen 1989 matches this one quite well and I assume it pertains largely or perhaps entirely to Tavenner Ranch 2
this is NOT Locality 4 of Wood and Konizeski 1965; however, Wood and Konizeski Locality 5 is from the same horizon only a few hundred yards away, and lithology matches that given by Pierce and Rasmussen
"? Parasminthus sp." is not documented in North America, see Korth 1994c
