Beginning International Stage:
Cambrian Stage 3
Fraction Up In Beginning Stage:
0
Beginning Date:
519.38
Ending Stage in Treatise Usage:
Lower Cambrian (“Lower Cambrian” in Trilobite volume of Treatise = current Cambrian Epoch 2 of international scale) (upper Qiongzhusian to lower Canglangpuan)
Ending International Stage:
