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.

Crossed Tracks: Mesolimulus, Archaeopteryx, and the Nature of Fossils [PDF]
, 2019 Organisms leave a variety of traces in the fossil record. Among these traces, vertebrate and invertebrate paleontologists conventionally recognize a distinction between the remains of an organism’s phenotype (body fossils) and the remains of an organism ...

And then there were none: decrease of origination and the decline of Conulariida
Papers in Palaeontology, Volume 12, Issue 2, March/April 2026.Abstract Although the evolutionary history of conulariids has been widely studied, previous works have focused mostly on limited time intervals. In this paper, we examine the diversity dynamics of the group throughout its entire history, using various mathematical approaches.

Tectonics, Volume 45, Issue 3, March 2026.Abstract In the Afghan Hindu Kush, the 223–209 Ma (≤800°C) Salang batholith is part of the Silk‐Road magmatic arc that was built on ∼40‐km‐thick Turan‐Karakum block continental crust. The batholith constitutes the hanging wall of the Herat‐Panjshir‐Badakhshan—the Paleo‐Tethys—suture zone, vestige of the subducted Paleozoic‐early Mesozoic Paleo‐Tethys ...
