Growth and feeding ecology of coniform conodonts [PDF]
PeerJ, 2021 Conodonts were the first vertebrates to develop mineralized dental tools, known as elements. Recent research suggests that conodonts were macrophagous predators and/or scavengers but we do not know how this feeding habit emerged in the earliest coniform ...

Lower Jurassic Conodonts From the Inuyama Area of Japan: Implications for Conodont Extinction [PDF]
Frontiers in Ecology and Evolution, 2023 It is generally accepted that conodonts went extinct at the end of the Triassic, but younger conodont fossils have been reported, and it is becoming clear that conodont extinction occurred asynchronously across different regions. Although some reports of

Marine Anoxia and Ocean Acidification During the End‐Permian Extinction
Geophysical Monograph Series, Page 325-340., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Boundary between the Porkuni and Juuru regional stages in the Neitla section, Estonia [PDF]
Estonian Journal of Earth Sciences, 2023 Conodonts and chitinozoans were studied from the Neitla section, which exposes the boundary between the Porkuni and Juuru regional stages. This level, although not proved biostratigraphically, has been traditionally considered to correspond to the ...

Thallium Isotopes Across the Smithian-Spathian Boundary: Evidence for Anoxia Throughout Most of the Early Triassic. [PDF]
GeobiologyABSTRACT Following the largest known Phanerozoic extinction, the end‐Permian mass extinction, the Early Triassic is often considered an interval of slow biotic recovery. During this time, the minor Smithian‐Spathian extinction occurred, further delaying the biotic recovery of this epoch.

Biostratigraphy, biofacies, and palaeoecology of the Upper Devonian deposits (Khoshyeilagh Formation) based on conodonts in the northeast of Iran (around Bojnord and Jajarm) [PDF]
Journal of Stratigraphy and Sedimentology Researches, 2021 In this study, the paleoecology, biostratigraphy, and biofacies of the Khoshyeilagh Formation hve been evaluated based on the found conodont species. The Khoshyeilagh Formation includes terrigenous-carbonate sequences, which contain conodonts of shallow ...

New contributions to the Ordovician biostratigraphy of the Western Precordillera, Argentina [PDF]
Estonian Journal of Earth Sciences, 2023 Upper Ordovician graptolites and conodonts are recorded from the Yerba Loca Formation in two sections, in the El Toro and Las Viudas creeks, from the El Tigre Range in the Western Precordillera of San Juan Province, Argentina. A collection of graptolites

Automatic identification of conodont species using fine-grained convolutional neural networks
Frontiers in Earth Science, 2023 Conodonts are jawless vertebrates deposited in marine strata from the Cambrian to the Triassic that play an important role in geoscience research. The accurate identification of conodonts requires experienced professional researchers. The process is time-

Aras Valley (northwest Iran): high-resolution stratigraphy of a continuous central Tethyan Permian–Triassic boundary section [PDF]
Fossil Record, 2020 The Permian–Triassic boundary section in the Aras Valley in NW Iran is investigated with respect to carbonate microfacies, biostratigraphy (particularly conodonts, nautiloids, and ammonoids), chemostratigraphy (carbon isotopes), and environmental setting.
