In the ICS geologic timescale, the Langhian is an age or stage in the middle Miocene Epoch/Series. It spans the time between 15.98 Ma and 13.82 (million years ago) during the Middle Miocene.
The analysis highlights Stratigraphic definition, Paleontology and Overview as prominent areas in the source structure around Langhian.
Source areas are shown by the number of related topics found in each part of the analysis. Use smaller areas too: they can reveal specialized angles and content gaps.
Smaller areas are not necessarily less important. They contain fewer connections in this analysis and can be useful for finding specialized angles or coverage gaps.
