摘要：
Two ichthyosaur taxa-Shastasaurus altispinus and Toretocnemus californicus- are present in the upper Carnian Dilleri Zone of the Antimonio Formation in the northern part of the Sierra del Alamo, northwestern Sonora, Mexico. Ichthyosaurs allow recognition of three intervals of Triassic time: (A) Early Triassic-primitive ichthyosaurs; (B) Middle Triassic-Mixosaurus-Cymbospondylus acme biochron; and (C) Late Triassic-shastasaurid biochron.
