Taxonomic list
• no direct stratigraphic correlation with main Vieja sequence
just below Whirlwind Breccia or "upper conglomerate breccia," and below the Crossen Trachyte, dated at 38.7 Ma "revised" (i.e., KA date revised to new constants)
reported as from "TMM 40131" by Wilson 1986, which is surely a lapsus
