Recalibrating the Devonian Time Scale

Three new timescales for the Devonian.
The biotic, climatic, and tectonic events of the Devonian cannot be correlated and investigated without a well-calibrated time scale. In our new paper out today lead by Claire Harrigan we recalibrated the Geologic Time Scale for the Devonian using three different conodont bio zone schemes, new U-Pb geochronology and a new approach to integrating Bayesian age depth modeling and astrochronologic constraints. The paper is available now in GSA Bulletin, and the modeling code is available on Github.
