New Information

Troodontid specimens were recovered from three localities in China by the Sino-Canadian expeditions between 1987 and 1990. These include a Lower Cretaceous form (Sinornithoides youngi), which is the most complete troodontid skeleton ever found, isolated bones from the Iren Dabasu Formation (?Turonian), and partial skeletons of Saurornithoides mongoliensis from Djadokhta-equivalent beds (?Campanian). These, and other specimens recently described from North America, allow a better assessment of the phylogenetic position of troodontids than has been possible before. Although troodontids have autapomorphies that eliminate them from consideration as bird ancestors, they are nevertheless one of the closest avian outgroups within the Theropoda.

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 Ordos Basin

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.

Left Humerus

A new specimen of an enantiornithean bird from the Lower Cretaceous Xiagou Formation of Gansu Province, northwestern China, consists of an articulated distal left humerus, ulna, radius, carpus, and manus. The specimen may represent a primitive enantiornithean because it lacks a longitudinal sulcus on the radius, has incompletely fused alular and major metacarpals, and possibly retains a remnant of a second phalanx on the minor digit. It differs from all other known enantiornitheans, and exhibits possible autapomorphies, including peculiar, flat humeral epicondyles, a pair of eminences on the distal minor metacarpal, and an enormous flexor tuberculum on the alular ungual. The specimen probably pertains to the same taxon as a previously described enantiornithean arm from Changma; the incompleteness of the taxon precludes erecting a new name, but it provides new information concerning enantiornithean diversity in the Early Cretaceous of central Asia.

The Ordos Basin

Cranial and postcranial remains from the Laolonghuoze locality in the Ordos Basin, Inner Mongolia (China), represent a previously unrecorded taxon of crocodyliform archosaurs from the Lower Cretaceous Luohandong Formation (Zhidan Group). Several cranial features indicate that this form is referable to the Atoposauridae, which were previously definitely known only from the Upper Jurassic and Lower Cretaceous of Europe. Certain derived characters further indicate that the Ordos material is closely related to, if not actually referable to, Theriosuchus. The Ordos atoposaurid differs from the species of Theriosuchus in only a few features. In view of its fragmentary nature, the new material is identified as cf. Theriosuchus sp. at present.
