产自中国云南下禄丰组(下侏罗统)的爬行动物不完美硕鳄的再研究
THE ENIGMATIC REPTILE PACHYSUCHUS IMPERFECTUS YOUNG, 1951FROM THE LOWER LUFENG FORMATION ( LOWER JURASSIC )OF YUNNAN, CHINA
摘要
Abstract
Phytosaurs are generally considered to have become extinct at the end of the Triassic Period,but several records have suggested that they survived into the basal Jurassic in Europe and Asia.The Asian record consists of Pachysuchus imperfectus from the Lower Lufeng Formation ( ? Hettangian-Sinemurian) of Yunnan,China.However,this specimen differs from phytosaurs in numerous respects and is more likely a poorly preserved,indeterminate sauropodomorph dinosaur skull.The referred specimens of this species are also regarded as indeterminate,thereby removing the post-Triassic record of phytosaurs from Asia.The European records of Jurassic phytosaurs are also shown to be doubtful,suggesting that this clade was restricted to the Late Triassic.关键词
