There are maps in "The Shaping of Middle Earth" and "The Atlas of Middle Earth" that show that they are in the same place. The Lake Nurn and the Sea of Rhun were once parts of the Inland Sea of Helcar. The River Running and another river both ran into the Sea of Rhun and the inland Sea of Helcar at the same place. The coasts of the Helcar seem to coer the later site of Osgiliath but never reach Mindolluin AKA the later ste of Minas Tirth. Mordor was definately once part of the Sea.
