摘要
During the late Middle and early Late Devonian , the Caiziyan section in the northeast of Guilin , Guangxi was located in the transitional zone between the carbonate platform facies and the deeper water pelagic facies.This is where both the benthic organisms ( including corals , brachiopods etc. ) and pelagic organisms ( including many index conodont species ) were relatively abundant. Therefore , the Caiziyan section could possibly serve as an important reference section for neriticpelagic correlation. Overall , the Late Givetian ( with a range from the conodont Schmidtognathus hermanni Zone through the end of the Givetian ) of the Caiziyan section is characterized by the wide distribution of the rugose coral Truncicarinulum and very common tabulate corals , which may be named the Truncicarinulum liujingense-Planocoenites guilinensis assemblage.The earliest Frasnian of the Caiziyan section is characterized by the relatively common rugose coral Phacellophyllum , which may be called the Phacellophyllum stereoseptatum coral fauna.Eight rugose and 10 tabulate coral species have been described and illustrated in the present paper , including one species of the Order Cystiphyllida , one species of the Suborder Ptenophyllina ( Order Stauriida ), and six species of the Suborder Columnariina ( Order Stauriida ) including one new species Phacellophyllum stereoseptatum Liao and Ma sp.nov. ; the tabulates all belong to the Order of Favositida , including the Pachyporidae ( two genera and two species ), the Alveolitidae ( six genera and seven species including two new species : Crassialveolites gaoshangtianensis Deng and Ma sp.nov.and Planocoenites guilinensis Deng and Ma sp.nov. ), and the Trachyporidae ( one genus and one species ).
