A hind limb of Saurornithoides mongoliensis from the Djadokhta Formation equivalent beds (Upper Cretaceous) of Bayan Mandahu (People's Republic of China) provides more information on the anatomy of the leg of this species than any other known specimen. Although it shares apomorphies of all troodontid theropods, the metatarsus is relatively longer and more derived than that of Troodon itself. The specimen is of an immature individual, less than half the size of the holotype. The degree of ossification suggests that troodontids were well developed at birth and that parental care was probably unnecessary.

An articulated neck of a large, mature sauropod, with enormously elongated cervical ribs, was discovered in strata of Late Jurassic age in the eastern Junggar Basin, Xinjiang, People's Republic of China. The animal is estimated to have originally measured 26 m in length, but was lightly proportioned relative to Brachiosaurus and Apatosaurus. Rudimentary spines on the anteriormost cervical vertebrae diagnose a previously undescribed species of Mamenchisaurus. Cranial parts associated with the neck do not support a close relationship with diplodocids. Mamenchisaurs apparently belong to an endemic Jurassic radiation of Asian sauropods.
