Collection methods and comments
Taxonomic list comments:Locality 20 of West and Dawson 1975; considerably to the NE of the main Sand Wash collecting area, and based on map of Stucky et al. probably includes three localities below Robin's Egg Blue Tuff, and therefore most likely equivalent to the very top of the Kinney Rim Mbr. fauna is included in the table listing the general Sand Wash fauna, and where there is clear evidence I have assumed that such records pertain only to Lang Springs no particular evidence that this is Uintan |
