Ph.D. graduate student Claire Harrigan and coauthors published their work on the numerical calibration of the Devonian time scale in the Geological Society of America Bulletin. This work features novel methodologies for integrating both radioisotopic and astrochronological age information into a Bayesian age modeling framework, as well as providing new U-Pb zircon ages for volcanic tuffs across the Emsian-Eifellian (Early-Middle Devonian) boundary.
