Insights into the canopy of the iconic Lepidodendron aculeatum, based on new articulated fossils from the Bashkirian (Pennsylvanian) of Hagen‐Vorhalle, Germany

Papers in Palaeontology, Volume 12, Issue 5, September/October 2026.
Abstract Lepidodendron aculeatum is an arborescent lycopod that populated the vast coal swamps in north‐western and central Europe during the late Carboniferous (Pennsylvanian) from the Bashkirian onwards, dominating the lush vegetation of tropical wetlands.

Devonian conodonts from Jones Island, northwest Washington

, 1984
Two small outcrops of limestone on Jones Island, northwest Washington, have yielded Devonian conodonts. Conodonts from locality 1, on the northern shore of the island, include Icriodus cf. I. brevis Stauffer, Icriodus cf. I.

Evaluating Forced Versus Plume‐Induced Subduction Initiation for the Talkeetna‐Bonanza Arc System: Implications for Permo‐Triassic Paleogeography of the North American Cordillera

Tectonics, Volume 45, Issue 9, September 2026.
Abstract The mechanisms by which new subduction zones form remain highly debated. Here we use Permo‐Triassic strata to evaluate potential mechanisms for initiation of the Talkeetna‐Bonanza Arc of the northern North American Cordillera. New mapping and analysis of Permian and Upper Triassic strata on the Alaska Peninsula suggest a period of uplift ...

Sections in the western slope of the south urals perspective for the choice of the famennian regional boundary stratotype point

Литосфера, 2015
The Bol’shaya Barma, Akkyr, Ryauzyak and Kuk-Karauk sections in the western slope of the South Urals are considered to be perspective sections for the identification of Famennian Regional Boundary Stratotype Point (RBSP).

A revised interpretation of the oral anatomy of Athenaegis chattertoni Soehn & Wilson (Vertebrata, Heterostraci) from the Silurian of Northwest Territories, Canada

Palaeontology, Volume 69, Issue 5, September/October 2026.
Abstract Heterostracans are pivotal in examining the evolution of feeding and the head in jawed vertebrates as the stem‐gnathostomes in which the oral apparatus is more commonly preserved. However, most analyses of their feeding, especially recent studies using modern 3D imaging methods, have focused on a specific subgroup, the Pteraspidiformes ...

Conodonts in Biostratigraphy. A 300-million-years long journey through geologic time [PDF]

Conodonts are tooth -like elements of a primitive chordate and are generally abundant in many marine sedimentary rocks deposited from the late Cambrian to the latest Triassic.

The new archosauriform track Pachychirotherium and the stepwise acquisition of digitigrady, cursoriality and erect stance in the group between the Permian and Triassic

Palaeontology, Volume 69, Issue 5, September/October 2026.
Abstract Archosauriforms were the most successful reptiles of the Mesozoic, becoming widespread and diverse during the Triassic. Yet, little is known of their origin, although it seems clear that it was before the end‐Permian mass extinction. An additional source of information comes from the early archosauriform footprint record.
