The Fruitiness of August. The Silurian SIBERIA, KAZAKHSTANIA, AND OTHER CONTINENTS

Separated from Baltica by the Pleionic Ocean (essentially the northwestern arm of the Paleotethys Sea), the paleocontinent of Siberia assumed an orientation rotated 180° from its present alignment (as recognized by the inverted position of Lake Baikal). A huge Siberian platform sea extended southward. Similarly, Kazakhstania was a neighbouring continent to the east in the same northern middle latitudes. North China (including Manchuria and Korea) and South China (the Yangtze platform) were two separate continents situated in a more equatorial position. In contrast to Siberia and Kazakhstania, most of North and South China were elevated above sea level during Wenlock time.
