摘要：A new infraorder of theropod dinosaurs,Segnosauria,is established which includes a single family Segnosauridae Perle,1979. Representatives of this infraorder display a highly distinctive,opisthopubic pelvis,a slender mandible and anteriorly edentulous lower and upper jaw. A new,alti-iliac type of saurischian pelvis is distinguished,which is characteristic of Segnosauria. Erlikosaurus andrewsi Perle gen. et sp. n. is preliminarily described;a short description of Segnosaurus galbinensis Perle,1979 and of a fragmentary pelvis determined on the infraordinal level are included.
