Meridian 90° : 420 Million Years ago

In this view most of the land is to the South (Gondwanaland) extending north-eastwards. The block close to the center of the view is part of present day Northern China and Japan. The island to the left is Mongolia. To the right at a three o'clock position is present day Indonesia connecting through Australia to the vast southern Gondwana super continent.
