Short summary
We introduce a new method to more precisely date ancient sediment layers using astronomical time cycles recorded in the rock. Unlike previous tools, it handles complex, multi-channel data without oversimplifying and gives clear estimates of dating uncertainty. This helps future research in better understand Earth's past climate, biological changes, and geologic events with greater confidence and accuracy.
