Geological Guide to Seven Sisters
Chalk cliffs at Seven Sisters
The upper chalk here contains a huge variety of fossils in a wide range of zones. The Seven Sisters, from west to east, are: Haven Brow, Short Brow, Rough Brow, Brass Brow, Flat Brow, Bailys Hill and Went Hill. More recently due to cliff erosion, an eighth sister has now appeared and this is called Flagstaff Brow. This can be seen between Brass Brow and Flat Brow. At Birling Gap, the Seaford Chalk Formation can be examined which yields a different variety of fossils from other Seven Sister cliffs. In the 1996 tour, 5 different species of echinoid were collected along with many brachiopods and bivalves.
