Taxonomic list
• although vague, this appears to be a single YPM locality not represented in other collections because none of the localities of Stirton and McGrew 1935, Webb 1969a, or Skinner and Johnson 1984 are at the mouth of Minnechaduza Creek; however, the Valentine Railway Quarries are about 4 mi S of this point
