| Collectors: | E. F. Riek, Heidi & John Anderson |
| Collection method comments: The Tennant family prepared the site by drainage of a significant storage dam, followed by removal of the weathered overburden so that the party could commence, immediately, to excavate productive sediment of this relatively rich insect horizon | |
| Taxonomic list comments:habitat described as "Sphenobaiera closed woodland" (Anderson and Anderson 2000 (ref. 6625)) | |
