Collection methods and comments
Reason for describing collection: | general faunal/floral analysis |
Museum repositories: | LACM |
Taxonomic list comments:most or all of the original collection described by Merriam 1916a as part of his "Cedar Mountain" fauna must be from UCMP 2027, which was designated as Stewart Spring sensu stricto by Teilhard and Stirton 1934 while Stirton indicates this is arbitrarily separated out from the Cedar Mountain fauna, Tedford et al. 1987 state that there is a clear stratigraphic distinction |
