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.

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

open access: yesSedimentology, EarlyView.
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

open access: yesSedimentology, 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.

“Is This Edible Anyway?” The Impact of Culture on the Evolution (and Devolution) of Mushroom Knowledge

open access: yesTopics in Cognitive Science, EarlyView.
Abstract Mushrooms are a ubiquitous and essential component in our biological environment and have been of interest to humans around the globe for millennia. Knowledge about mushrooms represents a prime example of cumulative culture, one of the key processes in human evolution.
