Short summary
StratoBayes is a novel Bayesian method for aligning stratigraphic data from multiple sites. It integrates diverse information, such as geochemical signals and radiometric dates, and provides robust age estimates with quantified uncertainty for all sites. We use StratoBayes to correlate lower Cambrian δ13C records from Morocco with an undated record from Siberia, and estimate the age of the world’s oldest trilobites.
