Diagenesis does not invent anything new: Precise replication of conodont structures by secondary apatite [PDF]
Conodont elements are important archives of sea/pore water chemistry yet they often exhibit evidence of diagenetic mineral overgrowth which may be biasing measurents.

Marine Anoxia and Ocean Acidification During the End‐Permian Extinction
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.

CONODONT BIOSTRATIGRAPHY OF THE "OCKERKALK" (SILURIAN) FROM SOUTHEASTERN SARDINIA [PDF]
Twenty-two conodont species are recognized in the Ockerkalk exposed in the Silius area (Gerrei, southeastern Sardinia). The fauna, which is the first reported from this peculiar facies, indicates a Ludlow and e.-m. Pridoli age for this limestone.

Thallium Isotopes Across the Smithian-Spathian Boundary: Evidence for Anoxia Throughout Most of the Early Triassic. [PDF]
ABSTRACT 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]
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 ...

Revision of the conodont zonation of the Wenlock–Ludlow boundary in the Prague Synform [PDF]
The regional zonation of the Wenlock–Ludlow boundary is established for the Prague Synform using refined data from updated conodont records. The following conodont zones have been recognized in the Prague Synform: the Ozarkodina sagitta sagitta Zone, the

The Llandovery (Silurian) conodont species diversity on the Upper Yangtze Platform, South China [PDF]
Conodonts are one of the stratigraphically most important fossil groups in the Silurian Period. We examine the regional diversity dynamics of the Llandovery condonts on the Upper Yangtze Platform.

Carbon isotope values in conodont elements from the latest Devonian–Early Carboniferous carbonate platform facies (Timan-Pechora Basin) [PDF]
The δ13Corg values and their variations in conodont elements of the latest Famennian–Tournaisian species Polygnathus parapetus Druce are considered. The conodonts studied come from the latest Famennian–Tournaisian interval of the Kamenka River section ...
