An extinct clade sister to Eumetazoa: On the phylogeny of the Cambrian chancelloriids

This study describes new fossils of chancelloriids, revealing their unique body plan and suggesting they are a basal clade sister to eumetazoans.

Not dasycladalean alga, but an Odyssey of the earliest Phanerozoic animal reef-builders

The paper reclassifies Protomelission? sp. as archaeocyath-like sponges, challenging previous interpretations and providing insights into early animal reef-building.

Organic matter influence on ooid formation: New insights into classic examples (Great Salt Lake, USA; Triassic Germanic Basin, Germany)

This study investigates ooid formation in two hypersaline environments, finding that organic matter plays a key role in their development, supported by structural and compositional analyses.

Deep origin of the long root tuft: the oldest stalk-bearing sponge from the Cambrian Stage 3 black shale of South China

The paper describes a new Cambrian sponge fossil with a long stalk, indicating an early adaptation to low-oxygen environments and a deep origin of stalk-bearing morphology in hexactinellid sponges.

Identification and current palaeobiological understanding of "Keratosa"-type non-spicular demosponge fossils in carbonates: with a new example from the lowermost Triassic, Armenia

The paper identifies and analyzes non-spicular demosponge fossils from the lowermost Triassic in Armenia, proposing criteria for their recognition and discussing their evolutionary significance.

Ooids forming in situ within microbial mats (Kiritimati atoll, central Pacific)

This study describes the formation of aragonite ooids within microbial mats in hypersaline ponds on Kiritimati atoll, highlighting the role of microbial communities and environmental factors in their development.

Paleoecological implications of Lower-Middle Triassic stromatolites and microbe-metazoan build-ups in the Germanic Basin: Insights into the aftermath of the Permian - Triassic crisis

This study examines Triassic microbialites in the Germanic Basin to understand their formation and ecological significance after the Permian-Triassic crisis.

Late Anisian microbe-metazoan build-ups ('stromatolites') in the Germanic Basin -- aftermath of the Permian -- Triassic Crisis

This paper analyzes late Anisian stromatolites from the Germanic Basin, revealing they are microbe-metazoan build-ups formed by microbes and non-spicular demosponges, not purely microbial structures.

Revisiting the phosphorite deposit of Fontanarejo (central Spain): new window into the early Cambrian evolution of sponges and into the microbial origin of phosphorites

The paper examines Cambrian phosphorites in Spain, revealing microbial processes in phosphatization and early sponge evolution.

Sedimentary factories and ecosystem change across the Permian-Triassic Critical Interval (P-TrCI) - insights from the Xiakou area (South China)

This study examines sedimentary factories and ecosystem changes during the Permian-Triassic mass extinction in the Xiakou area, revealing asynchronous environmental and biodiversity shifts.

The influence of microbial mats on travertine precipitation in active hydrothermal systems (Central Italy)

This study examines how microbial mats influence carbonate precipitation in hydrothermal travertines at different temperatures in Central Italy, finding that while microbial communities vary, carbonate structures remain consistent due to EPS-mediated mineralization.
