Sent it to soon. Here's an English language version with a slightly more accurate translation of the abstract. I fixed a few points of grammar. Still no open access pdf link, though.

Evolution of Pelvic Girdles of Stegosaurs in the Sichuan Basin.
Acta Geologica Sichuan 133(1): 62-64 + 69
Stegosaurs fossils in China occur mainly in the Sichuan basin, including 6 main genera: Huayangosaurus, Tuojiangosaurus, Gigantspinosaurus, Chungkingosaurus, Chialingosaurus, and Yingshanosaurus. All of them have pelvic girdles except Chialingosaurus. In addition to bone plates, stegosaurs pelvic girdle is an important identification characteristic. The five genera above are distributed over 4 successive fossil beds, allowing the Jurassic stegosaurs to have a continuous growth line. According to these characteristics, stegosaurs evolutionary relationship, from primitive to progressive type, has been found. The stegosaurs in the Sichuan basin has an evolutionary process, from Huayangosaurus, Chungkingosaurus, Gigantspinosurus, Tuojiangosaurus to Yingshanosaurus which shows that Huayangosaurus is still the most primitive stegosaur. Gigantspinosurus, one of the evolving stegosaurs, should be the transitional type between the Huayangosaurus and Tuojiangosaurus, and itâs a closer relative to Tuojiangosaurus. Yingshanosaurus is at the top of stegosaurs evolution in the Sichuan basin.Â
