South China (continent) South China (continent) South China, also known as South China Craton, South Chinese Craton, or Yangtze Craton, was an ancient continent (craton) that contained today's South and Southeast China, Indochina, and parts of Southeast Asia (i.e. Borneo and adjacent islands). South China had been part of past supercontinents, including Rodinia, Pannotia, Gondwana, Pangaea and Laurasia. About one billion years ago, during the late Proterozoic, the Rodinia supercontinent formed. South China was part of Rodinia. South China was bordered by the Mirovia Ocean to the north, Siberia to the east, Australia to the west, and Laurentia to the south. 750 million
Gondwana and barren landscape. West Gondwana drifted north during the Devonian which brought Gondwana and Laurasia close together. Global cooling contributed to the Late Devonian extinction (19% of marine families and 50% of genera went extinct) and glaciation occurred in South America. Before Pangaea had formed terrestrial plants, such as pteridophytes, began to diversify rapidly resulting in the colonisation of Gondwana. The Baragwanathia Flora, found only in the Yea Beds of Victoria, Australia, occurs in two strata separated by or 30 Ma; the upper assemblage is more diverse and includes Baragwanathia, the first primitive herbaceous lycopod to evolve from the zosterophylls.
