基金项目:This research is financially supported by the project of China Geological Survey on the Guanling fossil lagerst?tte and the environmental change (No. 1212010611603).
摘    要:It is suggested that the characters of Traumatocrinus hsui Mu infants change remarkably in different ages; however, the characters of adult individuals are comparatively stable. The present study examined specimens of infant and adult individuals of T. hsui. Based on these observations, the authors divided the ontogeny of T. hsui into four infant stages (infant stage I-IV) and one adult stage. In addition, the characters of the anal pyramid are supplemented and the infrabasal plates of T. hsui are confirmed in the present paper for the first time.
