The Albian is both an age of the geologic timescale and a stage in the stratigraphic column. It is the youngest or uppermost subdivision of the Early/Lower Cretaceous Epoch/Series. Its approximate time range is 113.2 ± 0.3 Ma to 100.5 ± 0.1 Ma (million years ago). The Albian is preceded by the Aptian and followed by the Cenomanian.
