Stratigraphy comments: Overall, based on zircon ages and chemostratigraphic studies, the Ruby Ranch Member ranges in age from ap-proximately middle Aptian to middle Albian (about 118 to 105 Ma) for the western Paradox Basin and northern San Rafael Swell. Other radiometric ages indicate the presence of upper Albian strata as well (Chure and others, 2010; Ludvigson and others, 2010a, 2015; Sprinkel and others, 2012)
