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.
