Open AccessFlume experiments reveal flows in the Burgess Shale can sample and transport organisms across substantial distances
The exceptionally preserved fossils entombed in the deposits of sediment-gravity flows in the Cambrian Burgess Shale of British Columbia have been fundamental for understanding the origin of major animal group...

Early bursts of diversification defined the faunal colonization of land
The colonization of land was one of the major events in Earth history, leading to the expansion of life and laying the foundations for the modern biosphere. We examined trace fossils, the record of the activit...

The Establishment of Continental Ecosystems
The colonization of land was a major evolutionary transition. Following a protracted prelude to the terrestrial invasion during the Ediacaran to Ordovician, the remainder of the Paleozoic experienced an explos...

The Conceptual and Methodological Tools of Ichnology
In order to be able to turn our attention to the potential of trace fossils to unravel information on evolutionary events, the conceptual and methodological tools of ichnology need to be briefly reviewed. Ichn...

The Prelude to Continental Invasion
The colonization of land by animals was a major evolutionary transition. Ichnologic evidence suggests that this process may have begun at the end of the Ediacaran interval with incursions into very shallow, ma...

Nest-seeking rock ants (Temnothorax albipennis) trade off sediment packing density and structural integrity for ease of cavity excavation
We investigated excavation and nest site choice across sediment-filled cavities in the ant Temnothorax albipennis. Colonies were presented with sediment-filled cavities, covering a spectrum from ones that should ...
