Ordosemys leios, n.gen., n.sp., from the Early Cretaceous Luohandong Formation, Zhidan Group, Ordos Basin, Inner Mongolia, is a primitive aquatic turtle with a reduced, fenestrated plastron. It shares with the members of the Centrocryptodira the presence of well-formed articular surfaces on the cervical and caudal vertebrae. Within the Centrocryptodira, characters of the cervical vertebrae suggest it is more closely related to the Polycryptodira than is the Meiolaniidae. Ordosemys shares with the Chelydridae the presence of two procoelous anterior caudals, but this character may be primitive for the Polycryptodira. Characters of the basicranial region of the braincase shared by Ordosemys and the Chelonioidea support a sister-group relationship between these two taxa, but a sister-group relationship between Ordosemys and the Polycryptodira is more strongly supported by characters shared by the Chelonioidea and other members of the Polycryptodira.

An articulated skeleton of a 1 m long theropod from Early Cretaceous strata in Inner Mongolia is clearly referrable to the Troodontidae, representing the most complete specimen known of this group of small carnivorous dinosaurs. The tail and neck of the animal were curled next to its body upon burial; the upper surface of the skeleton was badly damaged by erosion. Previously unknown details of troodont morphology include a quadratic contact with the braincase wall (forming part of a channel leading to the lateral depression), a presacral vertebral count possibly similar to that of most theropods, absence of ossified caudal tendons, presence of a rod-like clavicle, and absence of sternal ossifications. A new genus and species (Sinornithoides youngi n.gen., n.sp.) is established for the specimen on the basis of its short skull, laterally directed orbital rim of the frontal, and elongated hind limb. A reassessment of character distributions in other small theropods and primitive birds must be completed before troodontid affinities can be established with greater precision.

A New Species

In 1988, an incomplete skeleton of a stegosaurian dinosaur was found in Lower Cretaceous strata of the Ordos Basin of China by the Dinosaur Project (China – Canada – Alberta – Ex Terra). The material includes an articulated series of vertebrae from the last three cervicals to the first five caudals, and the right ilium. The specimen is identified as a new species called Wuerhosaurus ordosensis. It is the only Lower Cretaceous stegosaur known with an articulated series of dorsal vertebrae, which have been reduced to eleven in number.

The discovery of an Early Cretaceous bird from the Ordos Basin of Inner Mongolia (People's Republic of China) is reported. The specimen, collected by the Dinosaur Project (China – Canada – Alberta – Ex Terra) Expedition of 1990, includes scapulocoracoids, humeri, radii, ulnae and metacarpals. It is referred to the Enantiornithes.

Three New Species

A new genus with three new species of fossil Buprestidae, Sinoparathyrea bimaculata gen. et sp. nov., S. gracilenta sp. nov., and S. robusta sp. nov., from the Middle Jurassic Jiulongshan Formation of Inner Mongolia, China, are described. This is the earliest fossil record of buprestids in China and it is also the first record of buprestids from the Middle Jurassic Jiulongshan Formation of China.
