The swimming trace Undichna from the latest Devonian Hangenberg Sandstone equivalent of Morocco

Swiss Journal of Palaeontology, 2021
Trace fossils occur in several strata of the Devonian and Carboniferous of the eastern Anti-Atlas, but they are still poorly documented. Here, we describe a fossil swimming trace from strata overlying the Hangenberg Black Shale (correlation largely based

Devonian–Carboniferous extension and Eurekan inversion along an inherited WNW–ESE-striking fault system in Billefjorden, Svalbard [version 2; peer review: 2 approved, 1 not approved]

Open Research Europe, 2023
Background The Billefjorden area in central Spitsbergen hosts thick Lower–lowermost Upper Devonian, late–post-Caledonian collapse deposits presumably deformed during the Late Devonian Svalbardian Orogeny.

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

Frontiers 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]

Journal 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 ...

Fossil evidence of tylosis formation in Late Devonian plants

Nature 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

Royal 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.
