It was likely part of the Tethys Ocean, the researchers say, an ancient sea from the time of the Pangaea supercontinent. 

During the Permian, however, continental movement ceased for a time, as all of the world’s landmasses came together in a single supercontinent, known as Pangaea.

The earliest known dinosauromorphs lived in parts of the ancient supercontinent Pangaea that are now South America and southern Africa.
