Correlation of Hemingfordian and Barstovian land mammal assemblages, lower part of Caliente Formation, Cuyama Valley area, California
Reevaluation of faunas from the Caliente Formation allows the following correlations with similar ones elsewhere in California and in Nebraska. Padrones Spring local fauna (CIT 312: Ticholeptus smithi, Merychippus carrizoensis; 16.5-14.6 Ma) = Red Division Quarry LF (Barstow Formation 16.5-16.3 Ma), unnamed middle Hemingfordian local fauna (Red Valley Member, Box Butte Formation). Hidden Treasure Spring local fauna (UCMP V-5674, -5676: M. carrizoensis, Ticholeptus zygomaticus.; M. cf. M. seversus) . = lower Yermo local fauna (Barstow Formation). West Dry Canyon LF (lower) (last occurrence, M. carrizoensis; UCMP V-6766: first occurrence, medium-size Brachycrus laticeps) = unnamed local fauna (lower part, Unit 3, Punchbowl Formation), upper Yermo local fauna, Ginn Quarry local fauna (Hemingford Group). West Dry Canyon local fauna (upper) (last occurrence, medium-size B laticeps) = lower Green Hills local fauna (resistant breccia member, Barstow formation, upper Steepside Quarry), early late Hemingfordian, lower Sheep Creek local fauna (lower member, Sheep Creek Formation, Greenside, Long Quarries). Lower Dome Spring local fauna (UCMP V-5670, -5824, -6768: small B. laticeps) = early (pre-type) Barstovian upper Green Hills local fauna, (Camp, Green Hills, Oreodont Quarries; 16.3-15.0), lowest Snake Creek local fauna (lower member, Olcott Formation, Trojan Quarry; 16.7-15.1 Ma).
