Sampling comments: "discovered by Charles A. Repenning... who made preliminary collections. Subsequently, John A. White... quarried one locality (IMNH 67001) during 1967-1969. Additional collections were made by the senior author from this and nearby localities in the summers of 1977 and 1979"
"collected by surface crawling and prospecting, quarrying, dry screening loose unconsolidated sediments, and screen washing the more consolidated sediments"
a small collection was made at the nearby IMNH Locality 69004 (see) but no material is listed for IMNH Locality 79003, which is also discussed
