Uranium Isotope Evidence for Persistent Global Ocean Anoxia Across the Ediacaran-Cambrian Transition in Siberia. [PDF]
GeobiologyABSTRACT The enigmatic Ediacara biota represents Earth's earliest example of macroscopic, complex life, yet the driving forces promoting their mid‐Ediacaran evolution and subsequent extinction across the Ediacaran–Cambrian boundary remain speculative. If these were true animals requiring oxygen for aerobic respiration, their rise has often been linked ...

Science or Strategy? The Rejection of the Anthropocene Epoch Demands Transparency
Earth's Future, Volume 14, Issue 10, October 2026.Abstract In a recent Earth's Future article, Skelton and Noone (2025, https://doi.org/10.1029/2024ef005719) crystallized the dilemma facing the geoscientific community: the Anthropocene Working Group's (AWG) evidentiary case for an Anthropocene epoch is at least as strong as, and in their view stronger than, that for the Holocene.
