Taxonomic list

• 20 - 50 foot thick interval immediately below the "lower marker bed" and therefore at about the level of the Big Red Horizon; could be used as a calibration point based on superposition above Buckshot Ignimbrite, but distance above it is ambiguous (see Big Red Horizon)
composite Adobe Springs list is given by Wilson in fig. 8 and on p. 21
