摘要: The Middle and early Late Jurassic Qigu Shishugou Formations of the southern central Junggar Basin yielded teeth theropods (Theropoda indet.), sauropods (Eusauropoda stegosaurs. dinosaur assemblage is less diverse represented by smaller forms than in part basin. microwear Eusauropoda indet. resembles that observed Camarasaurus may have formed as a result biting through resistant woody materials. Carbon oxygen isotope data sauropod theropod indicate feeding within C3-plant ecosystem continental setting. Differences enamel δ13C δ18O values between are comparable to those other herbivorous carnivorous vertebrates, suggest at least partial preservation original dietary signals.
