主 题：rare star-like mouth disc Punctatus coelenterat functional morphology Kuanchuanpu Member of the Dengying Formation Ningqiang Shaanxi
摘 要：The Meishucun stage is the prelude in decipher-ing the Cambrian *** this prominent stage,rapid radioactive evolution and body-plan innovation have taken place and different associations of organism have been *** this paper we report several 3D-preserved rare star-like fossils with finely preserved soft tissues which were recovered from the Kuanchuanpu Member of the Dengying Formation in South Shaanxi,China in *** studying on functional morphology and analogy with mouthpart of Punctatus,there are evidences that this star-like organism approaches the coelenterates in systematic classification and the centre of star-like organism is its *** appearance of coelenterates marks the real beginning of metazoan ***,it has the prominent position in the origin and evolutionary history of *** the star-like organism represents the early types of coelenterate with original *** new materials provide new evidence for the origin,evolution and the functional evolution of the metazoan during the early stage of the Cambrian Explosion.
