Astrochronology of the Early Turonian-Early Campanian terrestrial succession in the Songliao Basin, northeastern China and its implication for long-period behavior of the Solar System

► Astronomical calibration of Early Turonian-Early Campanian terrestrial succession ► Ages of C33r/C34n and durations of three short reversals were inferred. ► Long-period astronomical forcing of lacustrine sedimentary sequences. ► Solar System may have experienced chaotic behavior in Early Turonian-Early Campanian.
