AbstractIn Guangxi, the Lower‐ Middle Devonian boundary beds yield abundant corals, brachiopods, stromatoporoids and conodonts. The former three were common in tropical and subtropical zones, while the last occurred only round the equator. This reveals that the South China Plate in the Early‐Middle Devonian was at or near the equator, which was also supported by palaeomagnetic study giving the palaeolatitude of the Guangxi Region at the time to be 0 ° 3
