Middle to Late Jurassic pelagites and gravity mass flow deposits of a displaced Neotethyan margin: Microfacies and biostratigraphical studies in Northeast Hungary [PDF]

open access: yesGeološki Anali Balkanskoga Poluostrva
Microfacies, depositional age and sedimentary environment were characterised for two Jurassic successions, which were deposited on the Adriatic microcontinental margin of the Neotethys Ocean. Investigations were carried out mostly on cores drilled in the

Did high Neo-Tethys subduction rates contribute to early Cenozoic warming? [PDF]

open access: yesClimate of the Past, 2015
The 58–51 Ma interval was characterized by a long-term increase of global temperatures (+4 to +6 °C) up to the Early Eocene Climate Optimum (EECO, 52.9–50.7 Ma), the warmest interval of the Cenozoic.

Transition from Paleotethys to Neotethys as a forgotten input for Vardar paleo-oceanic studies: Differences between the early Alpine, Early Cimmerian (Middle-Late Triassic) and ”Neocimmerian” (latest Jurassic) deformation stages („weak accretion”) [PDF]

open access: yesGeološki Anali Balkanskoga Poluostrva
An analysis of the extensive geoscientific legacy of the late Professors Milorad Dimitrijević (“Kvaks”) and Stevan Karamata, a century after their birth, shows that both authors published numerous studies on the Neo‐Tethys, primarily focused on the ...

A new elasmobranch fauna from the early Miocene of Sharbithat (Sultanate of Oman) reveals the teeth of an ancient fantail stingray

open access: yesGeologica Acta, 2022
Here we describe a new elasmobranch assemblage consisting of isolated dental material from the Aquitanian near-shore marine deposits of the Shuwayr and Warak formations at Sharbithat, in eastern Sultanate of Oman. The faunal composition clearly indicates
