Conodonts versus triassic climatic and eustatic changes [PDF]
, 2015 From astronomical, sedimentological, paleo-geographical and geochemical points of view, there is a general agreement that the Triassic period was exceptionally warm. The 51 MA long Triassic period started during the Siberian Traps and ended at the height

The role of conodonts in the global stratigraphic correlation on example of southern Siberia (Russia) and eastern Serbia [PDF]
Geološki Anali Balkanskoga Poluostrva, 2015 Conodonts are very precise tools for global stratigraphic correlation of Devonian deposits. They can be correlated at the level of standard conodont zones even for basins having very different geological structure.

Palaeontology, Volume 69, Issue 5, September/October 2026.Abstract Conodonts are known primarily from their microscopic tooth‐like skeletal feeding elements that occur commonly in jumbled assemblages in marine rocks from the late Cambrian to the Triassic–Jurassic boundary interval. Interpreting their evolution requires a scheme of positional homology of these elements within the feeding apparatus, information

The Llandovery–Wenlock boundary interval in west-central continental Estonia: an example from the Suigu (S-3) core section [PDF]
Estonian Journal of Earth Sciences, 2014 A gap corresponding to several conodont and chitinozoan zones occurs in the Llandovery–Wenlock boundary interval in some sections in the western coastal region of Estonia and on islands in the Muhu Strait.

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.Abstract The tectonic evolution of the northern margin of the North China Craton (NCC) remains controversial. In this study, we obtained zircon U–Pb ages, geochemical data, and Sr–Nd isotopic data for volcanic rocks, and detrital zircon ages for sedimentary rocks from the Yufutun, Tongqigou, and Benxi formations in central‐southern Jilin Province, NE ...

Carboniferous and Triassic conodonts from Syrian boreholes
, 1985 . A sparse but important collection of conodonts recovered from four boreholes in north-eastern and central Syria contains Neogondolella mombergensis, which is the first record of Triassic conodonts from Syria.

Thermal and Structural Reconstruction of an Eroded Foreland Basin: Central Appalachian Basin, USA
Basin Research, Volume 38, Issue 4, July–August 2026.New low‐temperature thermochronology and modelling reveal a complex thermal history for the central Appalachian Basin. Results indicate Carboniferous exhumation of the fold‐thrust belt and Mesozoic heating in the foredeep linked to the Rome Trough. Deeply buried Devonian source rocks were consequently pushed past the peak oil and gas windows.
