Taxonomic list comments:Ash Spring list of Wilson 1977b includes all and only taxa from TMM 40283; I believe there are no other TMM localities in Jeff Davis Co.
stratigraphic level uncertain as there are no useable marker beds in the immediate area, but supposed on faunistic grounds to be the youngest fauna in the Vieja sequence
Stevens and Stevens 1996 suggest that this is Orellan
