China Geology, 2020 : It has been an intense debate on the exact boundary between Ediacaran and Cambrian in the southwest Yangtze Block. The calibration of this critical boundary has a remarkable influence on the further investigation of the break-up of the Rodinia ...

Microhabitat Patchiness Structures Benthic Biodiversity in the Western Antarctic Peninsula
Ecology and Evolution, Volume 16, Issue 4, April 2026.Shallow benthic communities of the West Antarctic Peninsula cannot be considered uniform habitats but rather mosaics of microhabitats, each characterised by distinct macroalgal communities and associated fauna. Regional biodiversity and patterns are shaped by the number and types of microhabitats.

Behaviors that come out of a copepod's mind
Limnology and Oceanography, Volume 71, Issue 4, April 2026.Abstract Many aquatic environments are changing much faster than the gene pools of animals inhabiting them. To better predict how a copepod will behave, it is helpful to try to fathom the world from its sensory and cognitive system. Studies of genes, hormones, neuropeptides, and neural circuits can reveal underlying mechanisms while behavioral studies ...

Nature Communications, 2016 Macroscopic organisms are rare in the fossil record until the Ediacaran Period, beginning 635 million years ago. Here, Zhu et al. report the discovery of 1.56-billion-year-old carbonaceous compression fossils that provide evidence of the evolution of ...

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.Abstract The Ediacaran–Cambrian (∼635–539 Ma) geomagnetic field is characterized by unusually high reversal rates and markedly weakened field strength. Estimates of these reversal frequencies can reveal key aspects of deep Earth dynamics and their potential influence on surface environments and early complex life.

Neoproterozoic Microfossils from the Margin of the East European Platform and the Search for a Biostratigraphic Model of Lower Ediacaran Rocks [PDF]
, 2010 A ca. 600 m thick siliciclastic succession in northern Russia contains abundant and diverse microfossils that document early to middle Ediacaran deposition along the northeastern margin of the East European Platform.

Oxidation of the Ediacaran Ocean
Nature, 2006 Oxygenation of the Earth's surface is increasingly thought to have occurred in two steps. The first step, which occurred approximately 2,300 million years (Myr) ago, involved a significant increase in atmospheric oxygen concentrations and oxygenation of the surface ocean.

Unsteady Gypsum Cycling as a Driver of Cryptic Perturbations in the Ancient Carbon Cycle
Paleoceanography and Paleoclimatology, Volume 41, Issue 4, April 2026.Abstract Earth's sedimentary record preserves large, intermittent deposits of evaporitic gypsum (CaSO4·2H2O) that invoke the possibility of rapid changes in past seawater chemistry. In particular, strong imbalances between gypsum weathering and burial may drive changes in Earth's carbon cycle because calcium is a component of both gypsum and calcite ...
