摘要
齿孔虫作为一个生物类群,与氨类动物、花粉和孢子、甲壳类动物和脊椎动物一样,为其所在岩石的环境和年龄评估提供了替代线索。锥齿类被广泛用于三叠纪海洋生物地层学。然而,关于它们的多元素分类学和进化系(如世代、物种)有各种不同的讨论。尽管最初的研究报告称三叠纪的锥齿类物种大多是单膜的,但随后几年的研究坚持认为所有三叠纪的锥齿类都是多膜的。尽管曾尝试对一些三叠纪器型进行统计重建,但融合群和自然组合的发现随后证明,三叠纪锥齿类确实是多膜的,而且所有元素都共同存在于同一器型中。本文旨在阐明一些三叠纪下统锥齿动物的演化关系和排列。本文描述了Columbitella dagisi n. sp.。
Note on Lower Triassic Gondolelloid Conodont Rediversifications with Emphasis on the Spathian Recovery
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.
期刊介绍:
Journal of Earth Science (previously known as Journal of China University of Geosciences), issued bimonthly through China University of Geosciences, covers all branches of geology and related technology in the exploration and utilization of earth resources. Founded in 1990 as the Journal of China University of Geosciences, this publication is expanding its breadth of coverage to an international scope. Coverage includes such topics as geology, petrology, mineralogy, ore deposit geology, tectonics, paleontology, stratigraphy, sedimentology, geochemistry, geophysics and environmental sciences.
Articles published in recent issues include Tectonics in the Northwestern West Philippine Basin; Creep Damage Characteristics of Soft Rock under Disturbance Loads; Simplicial Indicator Kriging; Tephra Discovered in High Resolution Peat Sediment and Its Indication to Climatic Event.
The journal offers discussion of new theories, methods and discoveries; reports on recent achievements in the geosciences; and timely reviews of selected subjects.
