Skeletal Reconstruction

Remains of bipedal saurischians from lacustrine strata of Albian age in the Alxa ("Alashan") Desert of Inner Mongolia represent a new taxon and the most complete remains of an Early Cretaceous theropod so far discovered in Asia. A skeletal reconstruction generally resembles that of a moderately large prosauropod with long arms and a short tail. However, in its detailed morphology the reptile appears to be close to the ancestry of the Therizinosauridae Maleev, 1954 (for which Segno-sauridae Perle, 1979 is probably a junior synonym). These theropods are best referred to the Tetanurae of Gauthier, 1986. However, a provisional analysis of the distribution of therizinosauroid characters within tetanurans suggests the existence of two subordinate groups: the Carnosauria (Allosaurus, dromaeosaurids, and tyrannosaurids) and the Oviraptorosauria (including therizinosauroids, ornithomimids, troodontids, and oviraptorids).

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.

The One

The coarsening-upward clastic sequence at Tebch, Inner Mongolia, China, containing the dinosaur Psittacosaurus mongoliensis, comprises the remains of a fluviolacustrine system deposited in an extensional tectonic setting.The presence of Asteropollis sp. cf. Asteropollis trichotomosulcatus (Singh) Singh, 1983 in conjunction with the absence of tricolpate pollen indicates a Barremian or possibly early Aptian age. The overlying Tebch basalt, dated by the 40Ar/39Ar laser step-heating method, yields a mid-Aptian age of 110 ± 0.52 Ma.This chronology supports the argument that the Juifotang Formation of the Jehe Group in western Liaoning is Early Cretaceous, with the Jurassic–Cretaceous boundary very low within, or below, the base of the Jehe Group. Our data also suggest that the Berriasian–Hauterivian (Neocomian) age suggested for the one known Russian locality that has yielded P. mongoliensis (Shestakovskaya Svita at Gorno-Altayaskaya, Avtonomnaya Oblast) may be excessively old.

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.

Partial Skeleton

A partial skeleton of Oviraptor (which means egg thief), collected at Bayan Mandahu (Inner Mongolia, People's Republic of China) in 1990 was lying on top of a nest of eggs. Of the six known skeletons of this genus from Upper Cretaceous Djadokhtan sediments, this is the second occurrence in which the theropods were interacting with the eggs when they were buried by sand and dust during sandstorms. Two explanations for the association of Oviraptor with eggs are that the theropod may have been eating the eggs, or it may have been incubating and protecting them. Evidence presented suggests that the latter hypothesis is more likely. It is also conceivable that the female oviraptorid was in the process of laying eggs when she died.
