Triassic Rocks
 

The Triassic Rocks are the oldest rocks that form the World Heritage site and can be seen along the lower edges of the cliffs all the way from Exmouth in the west to Branscombe and forming all but the top caps of the hills and cliffs either side of Charmouth.

The Triassic rocks form the cliffs between Exmouth and up to a few miles east of Seaton. At Beer they temporaily dissapear below ground level and Cretaceous chalk forms the cliffs instead. NB. This last paragraph has been Supplied by Earth Science Advisor to the World Heritage Coast.

The Triassic period was from 250 million years ago to 200 million
