Eleven conodont zones are established for the Lower Triassic of the Motianling section in the Nanpanjiang Basin, South China. Detailed size measurements on 2244 P1 conodont elements demonstrate dynamic size variation patterns during the Early Triassic that are calibrated to the Early Triassic timescale and conodont zonation. Correlation of conodont size variation with various environmental indicators shows that these size changes are primarily controlled by rapidly changing and episodic… Expand

Abstract The biotic recovery following the Permian/Triassic boundary mass extinction was influenced by several secondary extinctions during the Early Triassic, of which the late Smithian crisis isExpand
Quantitative stratigraphic correlation of the Lower Triassic in South China based on conodont unitary associations
Abstract Unitary Association Method (UAM) analyses of conodont faunas from 28 sections spanning the biggest Phanerozoic end-Permian mass extinction and significant global environmental and ecosystemExpand
A proposed ontogenesis and evolutionary lineage of conodont Eurygnathodus costatus and its role in defining the base of the Olenekian (Lower Triassic)
Abstract The Early Triassic is a critical interval recording episodic climatic, environmental, and biotic events after the end-Permian mass extinction. A precise global timescale for this epoch isExpand
Size reduction of conodonts indicates high ecological stress during the late Frasnian under greenhouse climate conditions in South China
Abstract The Late Frasnian mass extinction (LFME) during extreme greenhouse conditions had a serious impact on biotic evolution. Herein, based on detailed size measurements of 1783 elements of theExpand
Post‐Permian Radiation
Events at the close of the Permian Period, led to the most severe mass extinction of the Phanerozoic. Sepkoski's ‘Palaeozoic Fauna’ suffered most; the surviving groups, more ‘modern’ in aspect, wereExpand
Lower Triassic conodont biostratigraphy of the Guryul Ravine section, Kashmir
Abstract The Guryul Ravine section in Kashmir, northern India is an important reference section for global Lower Triassic stratigraphy. Once a candidate Global Stratotype Section and Point (GSSP) forExpand
Evolutionary and ecophenotypic controls on bivalve body size distributions following the end-Permian mass extinction
It is hypothesized that both growth-limiting environmental conditions (deoxygenation and reduced primary productivity) and the extinction-induced absence of large species led to small-sized species dominating early Griesbachian benthic invertebrate communities. Expand


Rapid biotic rebound during the late Griesbachian indicates heterogeneous recovery patterns after the Permian-Triassic mass extinction
New fossil data from two Early Triassic (Griesbachian to Dienerian) sections from South China show unusually high levels of both benthic and nektonic taxonomic richness occurring in the lateExpand
Conodont size reduction and diversity losses during the Carnian Humid Episode in SW China
The enigmatic biotic and environmental changes during the Carnian Humid Episode (CHE) have been investigated in South China. The body size of conodonts, assessed as length of P1 elements, and theirExpand
High amplitude redox changes in the late Early Triassic of South China and the Smithian–Spathian extinction
Abstract The Early Triassic was a time of remarkably high temperatures, large carbon cycle perturbations and episodes of widespread ocean anoxia. The sediments in the Nanpanjiang Basin of South ChinaExpand
Abstract The significant increase of abundance and expansion of depositional environments that produced unusual sediments in the Early Triassic indicates stressed ecosystems in the aftermath of theExpand
Dynamic interplay between climate and marine biodiversity upheavals during the early Triassic Smithian -Spathian biotic crisis
Abstract In the aftermath of the Permian-Triassic boundary mass extinction (~252 Ma) ― the most dramatic biotic crisis of the Phanerozoic ― changes in climate, the carbon cycle, and biodiversityExpand
Lower-Middle Triassic conodont biostratigraphy of the Mingtang section, Nanpanjiang Basin, South China
Abstract The well-exposed stratigraphic sequences on the Great Bank of Guizhou (GBG) in South China provide important information for the understanding of various environmental settings during theExpand
Recovery pattern of brachiopods after the Permian–Triassic crisis in South China
In South China, the Changhsingian brachiopods are extraordinarily abundant and diverse, comprising 468 species in 144 genera. However, approximately 91% of brachiopod species were eliminated duringExpand
Size variation of conodont elements of the Hindeodus–Isarcicella clade during the Permian–Triassic transition in South China and its implication for mass extinction
Abstract Based on the analysis of thousands of conodont specimens from the Permian –Triassic (P–T) transition at Meishan (the GSSP of P–T Boundary) and Shangsi sections in South China, this studyExpand
Size variation of brachiopods from the Late Permian through the Middle Triassic in South China: Evidence for the Lilliput Effect following the Permian-Triassic extinction
Abstract Whether body size reduction (the Lilliput Effect) occurred in the Early Triassic invertebrates remains a matter of debate. Here, we investigate the size evolution of brachiopods spanning theExpand
Clade-dependent size response of conodonts to environmental changes during the late Smithian extinction
Abstract In contrast to the benthos whose taxonomic recovery was lagging way behind that of the nekton, highly diverse Smithian conodont and ammonoid faunas were profoundly decimated during the lateExpand
