Historical marker location:

Medora, North Dakota

( Marker is on Main Street north of 3rd Avenue, on the right when traveling north.)

North Dakota was once home to a massive inland sea, known as the Western Interior Seaway, which covered much of the state during the Late Cretaceous period around 80 million years ago. Fossils from marine creatures that lived in this sea can still be found in the state today.
