The global stratotype Section and Point for the base of the Middle Series and the third stage (Dapingian)

Key Points

• The global stratotype section identifies key geological timescale markers for the Dapingian stage's base.
• It emphasizes the significance of stratigraphy in understanding geological history's subdivisions across regions.
• The research outlines specific geological characteristics defining the Middle Series of the geological timescale.
• This designation aids in consistent geological mapping and reference across different regions globally.
