摘　　要：Conodonts,as a biotic group,next to ammonoids,pollen and spores,crustaceans and vertebrates,provide proxy clues for environment and age assessments of the rocks in which they occur.Conodonts are widely used for Triassic marine biostratigraphy.However,there are various discussions about their multielement taxonomy and evolutionary lineages(e.g.,generation,speciation).Although first studies reported that most Triassic conodont species were unimembrate,studies carried out in the following years maintained that all Triassic conodonts were multimembrate.Although statistical reconstructions of a number of Triassic apparatuses were attempted,the discovery of fused clusters and natural assemblages has subsequently demonstrated that Triassic conodonts are indeed multimembrate,and all of the elements exist together in the same apparatus.The present paper aims to clarify the evolutionary relationship and array of some Lower Triassic conodonts.Columbitella dagisi n.sp.is described.
