Knowra Jurassic Coast Jurassic Coast The Jurassic Coast is a 95-mile stretch of southern England’s coastline, from Exmouth to Studland Bay, where exposed rocks record roughly 185 million years of geological history.
Jurassic : A geological period lasting from about 201 to 145 million years ago, marked by diverse dinosaurs and the spread of flowering-plant precursors. Jurassic strata are one part of the coast’s much longer record, alongside Triassic and Cretaceous rocks.
Lulworth Cove : A near-circular bay in Dorset formed where waves breached resistant coastal rock and eroded softer rocks behind it. Its compact landform demonstrates how contrasting rock resistance shapes the coastline.
Mary Anning : An English fossil collector and paleontologist whose discoveries near Lyme Regis included important marine reptiles. Her finds from the coast helped establish the scientific significance of its fossil beds.
UNESCO World Heritage Site : A place recognized under the World Heritage Convention for outstanding cultural or natural value. The Jurassic Coast received this designation for its internationally significant geological record.
Ichthyosaur : An extinct marine reptile with a streamlined body and large eyes, known from fossils spanning much of the Mesozoic Era. Lyme Regis discoveries made ichthyosaurs central to early debates about extinction and ancient life.
Stratigraphy : The study of rock layers, their sequence, and their relationships in time and space. Reading the coast’s rock sequence reveals how environments changed through geological time.
Durdle Door : A natural limestone arch on the Dorset coast, formed by marine erosion along fractures in the rock. The arch is a conspicuous example of erosion acting on the coast’s exposed geology.
William Buckland : An English geologist and clergyman who studied fossils and became Oxford’s first professor of geology. He described fossils discovered by Anning and helped interpret the region’s geological evidence.
World Heritage Site : A place inscribed by UNESCO for cultural, natural, or mixed significance of outstanding universal value. The designation guides conservation and public interpretation of the coast’s geology.
Plesiosaur : An extinct marine reptile characterized by a broad body, four flippers, and a long or short neck. A nearly complete specimen found by Mary Anning near Lyme Regis helped establish the group’s anatomy.
