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.

Systematics of pterobranchs from the Cambrian Period Burgess Shales of Canada and the early evolution of graptolites

Greta M. Ramirez-Guerrero et al.

Summary: Pterobranchs originated in the basal Cambrian and are mostly known by their preserved tubes in the fossil record. This study focused on poorly known Middle Cambrian Burgess Shale pterobranchs, providing a complete description of certain species and establishing their phylogenetic relationships within the group.

(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.

Advanced Cambrian hydroid fossils (Cnidaria: Hydrozoa) extend the medusozoan evolutionary history

Xikun Song et al.

Summary: Primitive cnidarians are important for understanding the early evolution of metazoan body plans and life histories. An exceptionally well-preserved hydroid fossil found in the Upper Cambrian Fengshan Formation in northern China is proposed as a new genus, Palaeodiphasia gen. nov., associated with advanced hydrozoans typically showing loss of the medusa stage. Fossil evidence suggests that the strategy of medusa loss in advanced hydroids may have appeared as early as the Middle Devonian.
