The Thanetian is, in the ICS Geologic timescale, the latest age or uppermost stratigraphic stage of the Paleocene Epoch or Series. It spans the time between 59.2 and 56 Ma. The Thanetian is preceded by the Selandian Age and followed by the Ypresian Age (part of the Eocene).^[5] The Thanetian is sometimes referred to as the Late Paleocene.
