The English seaside town where the Earth’s history is written in stone
In short: In the Dorset town of Lyme Regis, the cliffs are constantly shifting. This geological instability, while a threat to the coast, serves a vital purpose: it exposes a continuous 185-million-year sequence of Triassic, Jurassic, and Cretaceous rock, revealing the ancient secrets of the Jurassic Coast.
The cliffs and beaches of Lyme Regis are part of a much larger World Heritage Site known as the Jurassic Coast, which stretches 153 kilometres from Orcombe Point to Old Harry Rocks. The landscape is defined by its dramatic geological exposures, where landslips frequently reveal well-preserved fossils. These include significant remains from the Early Jurassic, an epoch where high-quality fossil records are often rare. Notable discoveries include the Ichthyosaurus, Plesiosaurus, and the Scelidosaurus, one of the first known armoured dinosaurs.
Much of this scientific progress can be traced to the work of Mary Anning. Between 1811 and her death in 1847, the geological pioneer identified various marine reptile fossils in the cliffs east of the town. Her contributions were so significant that the town now holds an annual Mary Anning Day. Interestingly, the Geological Society of London, which commemorates her via a stained-glass window in the parish church, did not admit women as members until 1904.
However, this wealth of history comes at a physical cost. The coast is highly susceptible to erosion and landslips. In December 1839, the 'Dowlands Landslip' created a massive chasm over 300 feet deep, dislodging 45 acres of farmland and creating what became known as 'Goat Island'. More recently, in May 2008, a 400-metre section of land slipped onto the beach, described by police as the worst in a century. To combat these forces, a £16 million engineering project began in 2005 to stabilise the cliffs and protect the town from the encroaching English Channel.
