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

open access: yesSedimentology, 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

open access: yesSedimentology, 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.

Sedimentology and geomorphology of tufa barrages on rock coast shore platforms

open access: yesSedimentology, EarlyView.
ABSTRACT Despite tufa deposits being widely distributed and increasingly recognised globally on rock coasts, their distribution in the tidal frame and geomorphology is poorly understood. The distribution, sedimentology and geomorphology of tufa barrages on supratidal rock coasts are assessed and their controls established.

Sedimentological characterisation is a necessary prerequisite for interpretation of stable carbon isotope ratios of bulk sediment from reefal settings

open access: yesSedimentology, EarlyView.
ABSTRACT For most of Earth history, carbonate sediments deposited in shallow marine settings are the only remaining archive of changing biogeochemical cycles. All deep‐sea sediments older than >200 Ma have been subducted and are therefore lost from the record. Stable carbon isotope (δ13C) values of shallow marine carbonates are available for older time
