Greater Avalonia-latest Ediacaran-Ordovician peribaltic terrane bounded by continental margin prisms ( Ganderia, Harlech Dome, Meguma): Review, tectonic implications, and paleogeography

Ed Landing et al.

Summary: Avalonia is a distinctive region defined by unique uppermost Ediacaran-Ordovician rocks. It has been determined that Avalonia was an insular microcontinent rather than a part of Gondwana, with its origin and movement linked to the Avalonian transform fault (Atf). This finding challenges previous paleogeography and plate tectonics models.

(Re)proposal of three Cambrian Subsystems and their Geochronology

Ed Landing et al.

Summary: The Cambrian period is often divided into lower, middle, and upper sections for convenience, but this method lacks standard definition and is considered unsatisfactory. Recent proposals suggest dividing the global Cambrian into four series and three subsystems for more accurate classification.

Furongian (upper Cambrian) trilobites and agnostoids from the Alum Shale Formation of Bornholm, Denmark: revised taxonomy and biostratigraphy

Arne Thorshoj Nielsen et al.

Summary: The study reviewed and revised the Furongian trilobite-agnostoid fauna from the Alum Shale Formation of Bornholm, Denmark, updating the taxonomy of all species and illustrating the best preserved specimens. A total of 39 olenid and 5 agnostoid taxa were recorded, including a new species. The presence of three agnostoid and 14 trilobite zones was confirmed by fossils, with all six Furongian superzones developed on Bornholm.
