Diagenesis in Modern, Danish, Burned Pig Bone

, 2016
During archaeological excavations, burned bones are often found as a result of cremation, cooking or accidental fire. Even though the bones are burned, their elemental composition might still hold information about diet, habitat and health history in the

Into the Wild: Farm‐Derived Energy and Nutrients Enter Marine Food Webs With Carrying Capacity Implications for Aquaculture Management

Reviews in Aquaculture, Volume 18, Issue 3, June 2026.
ABSTRACT Marine aquaculture is expanding globally, yet its interactions with surrounding ecosystems remain complex and insufficiently understood. This study reviews the fluxes of energy and nutrients from three major aquaculture systems: finfish cages, suspended bivalves, and seaweed farms and considers their implications for ecosystem functioning and ...

Deposition and Diagenesis of Subtropical Microbial Carbonates

, 2017
The primary objective of this dissertation is to characterize freshwater microbial palustrine deposits, and assess how their textures and geochemical characteristics change over various stages of early burial and diagenesis in order to assess their ...

Microbial mats in dinosaur ichnocoenoses

Sedimentology, Volume 73, Issue 4, Page 1099-1120, June 2026.
ABSTRACT Until now, the significance of microbial mats in preservation of dinosaur tracks and in reconstructing the palaeoenvironment in which dinosaurs roamed was rarely studied. Dinosaur tracks are commonly found close to ancient aquatic bodies where moist sediment had once allowed footstep registration.

Microbial mats and thalassinid shrimp: Spatial and geochemical interactions in a modern intertidal environment

Sedimentology, Volume 73, Issue 4, Page 1001-1029, June 2026.
ABSTRACT This research examines the spatial and geochemical interactions between mat‐forming microorganisms and thalassinid shrimp in an intertidal flat situated on the shores of Willapa Bay, Washington, USA. The study serves as a contemporary analog for the relationships between mats and burrowing organisms in deep time.

Microbially generated ferruginous crusts: A potential biosignature of continental input in coastal settings

Sedimentology, Volume 73, Issue 4, Page 1225-1243, June 2026.
ABSTRACT Thin ferruginous sandy crusts are common on top of sandstone beds in the Early Permian post‐glacial deposits of the Paraná Basin in southern Brazil. These crusts usually preserve wrinkle structures, suggesting that they might be a product of microbial mediation.

Disentangling palaeoecological and outcrop controls on MISS occurrence in c. 1 Ga fluvio‐lacustrine facies of the Diabaig Formation, Scotland

Sedimentology, Volume 73, Issue 4, Page 883-913, June 2026.
ABSTRACT The c. 1 Ga Diabaig Formation of north‐west Scotland preserves diverse lacustrine and fluvial facies and abundant microbial and non‐microbial surficial sedimentary features. 172.6 m of section was logged across seven localities to assess the distribution of microbially induced sedimentary structures (MISS) relative to lithofacies, substrate ...

A tale of two microbialites: Stromatolites and microbially induced sedimentary structures

Sedimentology, Volume 73, Issue 4, Page 849-863, June 2026.
ABSTRACT Microbialites are biosedimentary structures built by microbial mats. Five microbialite groups are distinguished: stromatolites, thrombolites, dendrolites, leiloites and microbially induced sedimentary structures (MISS). This contribution discusses the two most abundant microbialite groups in marine settings, stromatolites and MISS.

Modern microbial landscape: Aerial mapping of microbially induced sedimentary structures forming in a coastal sabkha

Sedimentology, Volume 73, Issue 4, Page 1286-1306, June 2026.
ABSTRACT Microbially induced sedimentary structures (MISS) are considered important for understanding primitive life on Earth and for guiding the search for life on other planets. These structures are regarded as macroscopic fossils of early communities of unicellular organisms that did not produce skeletons or shells. In this study, field observations
