In the geologic time scale, the Changhsingian or Changxingian is the latest age or uppermost stage of the Permian period and the Paleozoic era as a whole. It is also the upper or latest of two subdivisions of the Lopingian Epoch or Series. The Changhsingian lasted from 254.14 to 251.902 Ma ago. It is preceded by the Wuchiapingian age/stage and is…
The analysis highlights Stratigraphic definitions, Changhsingian life and Notable formations as prominent areas in the source structure around Changhsingian.
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.
