The Real Jurassic Park: Geology field course along the south coast of England (TESC 417)
Project: The Cretaceous Chalk in Southern England
Student: Brieanna Graham
The chalk found along the Jurassic Coast is from the Late Cretaceous and is the youngest rock layer along the site. It is composed of billions and billions of photosynthetic calcium carbonate bodies called coccolithophores. The chalk formed in a warm, shallow sea over a period of about 45 million years. During this time the Atlantic Ocean was opening as North America and Europe drifted apart. Famous landmarks were the chalk can be seen are Old Harry Rocks and Lulworth Cove.
