Calibrating the temporal and spatial dynamics of the Ediacaran-Cambrian radiation of animals

FT Bowyer, AY Zhuravlev, R Wood, GA Shields… - Earth-Science …, 2022‏ - Elsevier
Abstract The Ediacaran-Cambrian transition, which incorporates the radiation of animals,
lacks a robust global temporal and spatial framework, resulting in major uncertainty in the …

Biosilicification drives a decline of dissolved Si in the oceans through geologic time

DJ Conley, PJ Frings, G Fontorbe… - Frontiers in Marine …, 2017‏ - frontiersin.org

Controls on the evolution of Ediacaran metazoan ecosystems: a redox perspective

F Bowyer, RA Wood, SW Poulton - Geobiology, 2017‏ - Wiley Online Library
A growing number of detailed geochemical studies of Ediacaran (635–541 Ma) marine
successions have provided snapshots into the redox environments that played host to the …

Innovation not recovery: dynamic redox promotes metazoan radiations

R Wood, DH Erwin - Biological Reviews, 2018‏ - Wiley Online Library
Environmental fluctuations in redox may reinforce rather than hinder evolutionary transitions,
such that variability in near‐surface oceanic oxygenation can promote morphological …
