Abstract Conodonts have played an important role in the construction of a Triassic timescale. Each of the stage boundaries is reviewed in the context of their evolving conodont faunas. The base Triassic (Induan) is defined by the appearance of Hindeodus parvus, which developed from H. praeparvus; a parallel zonation is provided by Neogondolella species. For the Induan–Olenekian boundary, the appearance of Neospathodus waageni sensu lato within a plexus of similar species is favoured as the… Expand
Early Anisian (Middle Triassic) Conodonts from Romania and China, with Comments on Their Role in the Recognition and Correlation of the Base of the Anisian
The Olenekian-Anisian Boundary (OAB) interval is an important time in Earth history, reflecting the last phase of marine ecosystem recovery in the aftermath of the end-Permian mass extinction.Expand
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
Middle Triassic (Anisian) Conodont Biostratigraphy at the Shaiwa Section, Guizhou, South China
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 ShaiwaExpand
Middle Triassic conodont assemblages from the Germanic Basin: implications for multi-element taxonomy and biogeography
Conodonts have been a key tool for biostratigraphical, evolutionary and palaeobiogeographical studies, and the Germanic Basin has been one of the most important regions for these studies. However,Expand
Quantitative stratigraphic correlation of Tethyan conodonts across the Smithian-Spathian (Early Triassic) extinction event
Abstract Three small-scale extinctions occurred in the Early Triassic with one of them recognized close to the Smithian-Spathian boundary. In the last two decades, the end-Permian mass extinction asExpand
Early Triassic (Induan-Olenekian) conodont biostratigraphy, global anoxia, carbon isotope excursions and environmental perturbations: New data from Western Australian Gondwana
The Early Triassic Induan-Olenekian Stage boundary (Dienerian-Smithian sub-stage boundary) has been identified at a depth of 2719.25m in the petroleum exploration well Senecio-1 located in theExpand

New Upper Triassic Conodont Biozonation of the Tethyan Realm
Conodonts are biostratigraphically very important microfossils in the Upper Triassic, occurring in different marine habitats, from deep-ocean to shallow-shelf waters. Because of their greatExpand
Conodont biostratigraphy of a new Permo-Triassic boundary section at Wenbudangsang, north Tibet
Abstract The Wenbudangsang section is a newly discovered continuous succession of marine carbonates that straddles the Permian–Triassic boundary (PTB), extending from the late Permian to the earliestExpand
Challenging Darwin: Evolution of Triassic Conodonts and Their Struggle for Life in a Changing World
Abstract The phylogeny and distribution of Triassic conodonts reveal many aspects of their natural history. Conodonts incorporate the morphologic response to temperature as well as to eustaticExpand
