Short summary
Sedimentary rocks are typically dated indirectly, by comparing the fossil content of basins with the geological timescale. In this study, we employed an absolute dating approach to date 19\,Myr old sediments in the Paris Basin, using uranium–lead dating of calcite nodules associated with soil formation. The precision of our new ages enable more accurate comparisons (independent of their fossil contents) between the Paris Basin and other basins of similar age.
