The Odisha Coastal Plains or Utkal Plains are the sedimentary landforms of recent origin. Geologically they belong to the Paleogene and Neogene ages (approximately 65 to 2.6 million years ago). Their western boundary is at around 250 feet eastern ghats and they have a nearly straight shoreline in east. This region stretches from the Subarnarekha basin in the north to the Rushikulya basin in the south.
