This supercontinent formed at the end of the ____________________ Era.

A. The Paleozoic Era began with the breaking up of the super continent called Pannotia. At the end of the period (about 300 million years later) the land masses had merged again to form a new super continent called Pangaea.

Answer 2

The end of the Pennsylvanian Period was marked by a dry climate, the gradual disappearance of the vast coastal coal swamps and changes in plants and animals. These changes were brought about by the assemblage of the super-continent, Pangaea, and retreat of the shallow seas from interior continental areas.
