Tectonics, Volume 45, Issue 9, September 2026.Abstract The Fennoscandian Shield potentially hosts the longest continuous habitable conditions for Earth's deep biosphere. Billion‐year equilibrium freeboard conditions of cratons and the longevity of deep biosphere microbial communities are directly related through the thermal histories of rocks that host these communities.

The Ediacaran Biotas in Space and Time [PDF]
Integrative and Comparative Biology, 2003 The "Ediacaran organisms," which preceded and overlapped the Cambrian radiation of metazoans, include many fossils whose systematic positions remain contentious after over fifty years of study. It might seem that nothing particularly useful can be learned from a biota full of oddballs. However, analyses of the distribution of the Ediacaran organisms in

Evolution: The Making of Ediacaran Giants [PDF]
Current Biology, 2014 Some of the enigmatic Precambrian organisms in the Ediacaran Period grew large and stood tall above the seafloor. Canopy flow modeling suggests that their large size was optimized for access to flow in order to facilitate osmotrophic nutrient uptake in low-flow environments.

The mechanisms by which soft-bodied organisms were preserved in late Ediacaran deep-marine environments are revealed by petrographic and geochemical investigation of fossil-bearing surfaces from the Conception and St. John's groups (Newfoundland, Canada).

Ediacaran Doushantuo-type biota discovered in Laurentia
, 2020 The Ediacaran period (635-541 Ma) was a time of major environmental change, accompanied by a transition from a microbial world to the animal world we know today. Multicellular, macroscopic organisms preserved as casts and molds in Ediacaran siliciclastic

Scratch circles from the Ediacaran and Cambrian of Arctic Norway and southern Africa, with a review of scratch circle occurrences [PDF]
, 2018 Scratch circles—bedding plane parallel sedimentary structures formed by the passive rotation of a tethered organism into the surrounding sediment—are relatively rare in the geological record. Here new occurrences of scratch circles are described from the
