The Truong Son, Loei-Phetchabun, and Kontum Terranes in Indochina: Provenance, Rifting, and Collisions

open access: yesFrontiers in Earth Science, 2021
The three main regions of Indochina are defined as the Truong Son, Loei-Phetchabun, and Kontum terranes. The aim of this review is to integrate numerous petrological studies with sedimentary, palaeontological, and provenance studies in order to construct

Biostratigraphy, biofacies, and palaeoecology of the Upper Devonian deposits (Khoshyeilagh Formation) based on conodonts in the northeast of Iran (around Bojnord and Jajarm) [PDF]

open access: yesJournal of Stratigraphy and Sedimentology Researches, 2021
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 ...

A new Late Devonian genus with seed plant affinities. [PDF]

open access: yesBMC Evol Biol, 2015
Many ovules of Late Devonian (Famennian) seed plants have been well studied. However, because few taxa occur with anatomically preserved stems and/or petioles, the vascular system of these earliest spermatophytes is little understood and available data come mostly from Euramerica.

Fossil evidence of tylosis formation in Late Devonian plants

open access: yesNature Plants, 2023
Tyloses are swellings of parenchyma cells into adjacent water-conducting cells that develop in vascular plants as part of heartwood formation or specifically in response to embolism and pathogen infection. Here we document tyloses in Late Devonian (approximately 360 Myr ago) Callixylon wood. This discovery suggests that some of the earliest woody trees

Locomotory behaviour of early tetrapods from Blue Beach, Nova Scotia, revealed by novel microanatomical analysis

open access: yesRoyal Society Open Science, 2021
Evidence for terrestriality in early tetrapods is fundamentally contradictory. Fossil trackways attributed to early terrestrial tetrapods long predate the first body fossils from the Late Devonian.

Stages of development of the Middle-Late Devonian ICHTHYOFAUNA (Placodermi: Antiarchi) from the northern Eurasia

open access: yesИзвестия высших учебных заведений: Геология и разведка, 2019
Three stages, namely Middle Devonian (I), Early Late Devonian (II) and Late Late Devonian (III), are distin-guished in the evolution of antiarchs (Placodermi, Antiarchi) in the Middle-Late Devonian of Northern Eurasia.
