Microbial influence on the formation and subsequent changes of vertebrate tracks: field experiments on present‐day coastal sediments

Sedimentology, EarlyView.
ABSTRACT The presence of microbial mats is often invoked to explain the good preservation of vertebrate tracks, because they can cover and biostabilize such structures. However, microbial influence on the sediment properties when the track is made and on the track characteristics has not been so thoroughly analysed.

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.

A redescription of <i>Glyptochelone suyckerbuykii</i> (Ubaghs, 1879), an enigmatic fossil sea turtle (<i>Chelonioidea</i>) from the Maastrichtian of the Netherlands and Belgium, sheds new light on fossil sea turtle shell variation and neural bone homology. [PDF]

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.
