A Shallow‐Marine Ecosystem Before Initial Tibetan Plateau Uplift

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract The uplift of the Tibetan Plateau profoundly influences global atmospheric circulation, sediment transport, and biodiversity, but its pre‐uplift marine paleoenvironment remains poorly understood. Here we report the first discovery of an in situ benthic fossil assemblage from the Puga area in central Tibet, which was deposited on a shallow ...

Internal waves as controlling factor in the development of stromatoporoid-rich facies of the Apulia Platform margin (Upper Jurassic-Lower Cretaceous, Gargano Promontory, Italy)

, 2019
During the Late Jurassic, stromatoporoid-rich buildups were developed in south and intra-Tethys realms. These stromatoporoid buildups are mainly characterized by the high percentage of intraclastic-bioclastic debris, as main components of buildup bodies.

Raman Line Scan Analyses and a New Hypothesis for the Formation of Anatase‐Hosting Microbialites: Study of the Stromatolites From Saint‐Jean‐de‐la‐Rivière, Cotentin, France

Journal of Raman Spectroscopy, Volume 57, Issue 8, Page 1463-1480, August 2026.
Micrometer analysis of millimeter lines of Raman spectra concludes in the association of anatase and graphitized organic matter (graphogen). The photosynthetic microorganisms at the origin of the microbialites produce O2, which is transformed by TiO2 into reactive species that, in turn, decompose the organic matter of the microorganisms.

DEVONIAN CALCAREOUS ALGAE, TABULATE CORALS AND BIOCLAUSTRATIONS FROM THE KARAKORUM MOUNTAINS (NORTHERN PAKISTAN)

Rivista Italiana di Paleontologia e Stratigrafia, 2007
During several field work campaigns to the Karakorum Mountains samples containing Devonian macrofossils were collected by M. Gaetani and P. Le Fort, mostly in the uppermost Yarkhun Valley (Northern Pakistan).

Palaeoecology of Middle Devonian epizoans and their Paraspirifer hosts

Palaeontology, Volume 69, Issue 2, 2026.
Abstract The Silica Shale brachiopod, Paraspirifer bownockeri, of Ohio and Michigan, USA, preserves a unique window into Middle Devonian communities, as individuals hosted numerous epibionts. Herein, we use qualitative and quantitative methods to test hypotheses regarding the palaeoecology of these brachiopod hosts and their epibionts.

Palaeobiology, ecology, and distribution of stromatoporoid faunas in biostromes of the mid-Ludlow of Gotland, Sweden [PDF]

, 2008
Six well exposed mid−Ludlow stromatoporoid−dominated reef biostromes in four localities from the Hemse Group in southeastern Gotland, Sweden comprise a stromatoporoid assemblage dominated by four species; Clathrodictyon mohicanum, “Stromatopora” bekkeri,

CORAL COMMUNITIES, ZONATION AND PALEOECOLOGY OF AN UPPER JURASSIC REEF COMPLEX (ELLIPSACTINIA LIMESTONES, CENTRAL APENNINES, ITALY)

Rivista Italiana di Paleontologia e Stratigrafia, 2018
This work describes and analyzes an original collection of fossil corals from the Ellipsactinia Limestones (Kimmeridgian-Tithonian), exposed in the Marsica area (central Apennines, Italy), focusing on taxonomy and paleoecology. 43 species grouped into 32

Sediment‐stressed reefs over the past 420 Myr

The Depositional Record, Volume 12, Issue 1, February 2026.
In order to fully elucidate the relationship between siliciclastic sedimentation and reef development, there needs to be a significant step change in how we record ancient and recent reefs. Only through the collection of constrained quantitative data, we can progress beyond the largely conjectural associations postulated for many ancient reefal systems.

Carbonate sedimentology: An evolved discipline

The Depositional Record, Volume 12, Issue 1, February 2026.
Abstract Although admired and examined since antiquity, carbonate sediment and rock research really began with Charles Darwin who, during a discovery phase, studied, documented and interpreted their nature in the mid‐19th century. The modern discipline, however, really began after World War II and evolved in two distinct phases.

Devonian stromatoporoid interactions at the Falls of the Ohio State Park, Clarksville, Indiana [PDF]

, 2018
Stromatoporoids are calcitic sponges that occurred in the fossil record from the Early Ordovician to Late Devonian period. These sponges interacted with other organisms, especially rugose and tabulate corals.
