The Sevatian of the late Norian is one of the key intervals in biotic turnover and in changes of paleoclimate and paleoenvironments. Conodont faunas recovered from two sections of upper Norian strata of the Dashuitang and Nanshuba formations near Baoshan City in western Yunnan province provide new insights into the diversity and biostratigraphy of...

The South Qinling Belt is a key area for understanding the collisional history of the South China and North China blocks during the Lopingian (late Permian) and Triassic. This paper establishes the first integrated timescale based on conodont biostratigraphy and δ¹³Ccarb records from a continuous end Permian to the end-Early Triassic succession at...

The Nanpanjiang Basin is a key area for paleontological and biostratigraphical study of the Middle Triassic. Herein we studied Middle Triassic conodonts from a well-exposed section, the Shaiwa Section, which is located at the northwest end of the Nanpanjiang Basin. A total of six Anisian conodont zones are recognized; in ascending order, they are:...

Based on a study of 49 conodont and 57 geochemical samples from the Upper Triassic, carbonate-dominated Dengdengqiao Formation, Qinling Basin, China, the Carnian conodonts and carbon isotope records are first reported. Two genera and four species have been identified amongst 87 conodont elements: Mosherella praebudaensis, Mo. longnanensis sp. nov.,...

Almost all aspects of conodont research rely on a sound taxonomy based on comparative analysis. This is founded on hypotheses of homology which ultimately rest on knowledge of the location of elements in the apparatus. Natural assemblages—fossils that preserve the articulated remains of the conodont skeletal apparatus—provide our only direct eviden...

Abundant platform-bearing gondolellid conodonts, including Scythogondolella mosheri (Kozur and Mostler), Sc . phryna Orchard and Zonneveld, and Sc . cf. milleri (Müller), have been discovered from the Yiwagou Section of Tewo, together with Novispathodus waageni waageni (Sweet) and Nv . w . eowaageni Zhao and Orchard. This is the first report of Smi...

Knowledge of the conodont skeleton, in terms of the morphology of the elements and the positions they occupy, provides the foundation for understanding of homology, taxonomy and evolutionary relationships in conodonts. This knowledge also underpins analyses of conodont functional morphology and feeding. Direct evidence of skeletal anatomy and appar...

New collecting at a biostratigraphically highly-resolved deep-water section in South China, reveals a brief (a few tens of thousands of years) but measurable delay in extinction timing relative to contemporaneous, shallower water sections. Foraminifers and conodonts in the Bianyang section show a sharp extinction at the top of Hindeodus changxingen...

A latest Changhsingian (latest Permian) foraminiferal fauna composed of 19 species (belonging to 10 genera) was recovered from the Daxiakou section in Xingshan County, Hubei Province, South China. Compared to contemporaneous faunas in South China, the Daxiakou fauna displays unique features: (1) nodosariids are the dominant forms in abundance and d...

The change of the primary productivity across the Permian-Triassic boundary (PTB) remains controversial. In this study, records from two deep-water sections in South China (Xiakou and Xinmin sections) show the primary productivity decreased gradually from the latest Permian to the earliest Triassic, and five evolutionary stages Increase-Decrease-Re...

A quantitative reconstruction method of paleo-primary productivity is present on the basis of the investigation on the faunal record in cherts. By obtaining the accumulation rate of radiolarian shells in the cherts and considering all aspects of silica loss before burial, such as dissolution in the eutrophic zone or within the sediments, it is poss...
