New stratigraphic data for the Lower Cretaceous Tirgan Formation, Kopet-Dagh Basin, NE Iran [PDF]

Arabian Journal of Geosciences, 2019
In this contribution, we describe a section through the Lower Cretaceous shallow-water platform sediments (Tirgan Formation) from the Kopet-Dagh basin (northern Tethys), which is located near Tirgan village, NE Iran. We used benthic foraminifera and planktonic organisms for biostratigraphy associated to the carbon isotope chemostratigraphy to constrain

Cenozoic evolution of Neotethys and implications for the causes of plate motions [PDF]

, 2003
Africa-North America-Eurasia plate circuit rotations, combined with Red Sea rotations and new estimates of crustal shortening in Iran define the Cenozoic history of the Neotethyan ocean between Arabia and Eurasia. The new constraints indicate that Arabia-

Evolution of Mayflies (Ephemeroptera) Across the Palearctic Mountains: The Biogeographical Links Between the Caucasus and Adjacent Ranges, Central Asia and the Himalayas

Zoologica Scripta, Volume 54, Issue 6, Page 870-883, November 2025.
ABSTRACT The biodiversity of the highest Palearctic mountains is extraordinary, yet its evolution and biogeographic links from a global perspective remain poorly understood. This study focuses on the diversification and biogeography of mayflies (Ephemeroptera) distributed across several prominent mountain ranges, including the Caucasus and adjacent ...
