Microbial mats in dinosaur ichnocoenoses

Sedimentology, EarlyView.
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.

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

Sedimentology, EarlyView.
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.

Variations in downslope activity and bottom current dynamics in a land‐detached submarine channel system since the Last Glacial Maximum

Sedimentology, EarlyView.
ABSTRACT The Gollum Channel System is a land‐detached large‐scale canyon‐channel system situated offshore southwest Ireland on the Northeast Atlantic margin. The system has been considered inactive with downslope gravity flows since the last glacial period, but geophysical data in some of its branches do suggest Holocene activity.
