10 Fun Facts About Lyme Regis’ Jurassic Coast
Few places in the world tell Earth’s story as clearly as the Jurassic Coast, and Lyme Regis sits right at its heart. Stretching for 95 miles from Exmouth in Devon to Studland Bay in Dorset, this World Heritage coastline reveals 185 million years of geological history. But beyond the fossils and famous cliffs, there are plenty of fascinating facts that make Lyme Regis and its Jurassic Coast truly special. Here are ten that locals love to share — and visitors never forget.
1. It’s England’s Only Natural World Heritage Site
The Jurassic Coast was awarded UNESCO World Heritage status in 2001 — the same level of recognition given to sites like the Grand Canyon or the Great Barrier Reef. This isn’t because of its beauty alone, but because of the way the rocks, cliffs, and beaches reveal an unbroken record of Earth’s history. Every layer tells a story, from tropical seas to icy ages, preserved perfectly along the coast you can walk today.
2. The Name ‘Jurassic Coast’ Comes from Just One of Its Eras
Although the whole coastline is called the Jurassic Coast, it actually covers three major geological periods: the Triassic, Jurassic, and Cretaceous. Together, these span an incredible 185 million years of time. Around Lyme Regis, the cliffs mostly represent the Jurassic period — around 200 to 145 million years ago — which is why this section is particularly rich in marine fossils like ammonites and ichthyosaurs.
3. Lyme Regis Is Known as the Fossil Capital of Britain
It’s no exaggeration to say that Lyme Regis is one of the most important fossil locations in the world. The town’s cliffs and beaches are constantly eroded by the sea, revealing new finds every day. From ammonites and belemnites to ancient marine reptiles, these discoveries have helped scientists understand prehistoric life in extraordinary detail. Fossil walks led by local experts remain one of the most popular activities for visitors year-round.

4. Mary Anning Made History Here — and Changed Science Forever
Born in Lyme Regis in 1799, Mary Anning became one of the most influential fossil hunters of all time. She discovered the first correctly identified ichthyosaur skeleton at just 12 years old, followed by several groundbreaking finds that challenged scientific thought in the 19th century. Despite her limited formal education, her meticulous work earned her posthumous recognition as a pioneer of palaeontology. You can still visit the spot on the beach where many of her fossils were found.
5. Landslides Keep the Coast Alive
The spectacular cliffs that make Lyme Regis so famous are constantly changing. This dynamic landscape is shaped by natural erosion, which causes landslides and rockfalls — especially after heavy rain. While this means the coastline looks slightly different each year, it also ensures new fossils are continually exposed. The combination of danger and discovery gives the area its distinctive energy and makes every fossil walk a true adventure.
6. The Jurassic Coast Has a Colour Code of Its Own
From the red rocks of East Devon to the pale chalk of Dorset, the Jurassic Coast acts like a natural timeline made of colour. Around Lyme Regis, the cliffs are rich in dark grey and blue clays known as the Blue Lias formation — layers that formed under ancient seas where countless creatures were buried and fossilised. If you notice the banded cliffs near Church Cliff Beach, you’re looking directly at this geological layer.
7. It’s a Paradise for Walkers and Photographers
One of the best ways to experience the Jurassic Coast is on foot. The South West Coast Path runs through Lyme Regis and connects to some of the most breathtaking views in England. A favourite local route is the cliff-top walk to Charmouth, where you can look down over the beach and spot fossil hunters below. On a clear day, the layers of the cliffs glow in golden light, making it a dream for photographers and nature lovers alike.

8. You Can Trace an Ancient Ocean Floor Beneath Your Feet
The rocks that make up the cliffs at Lyme Regis were once part of the seabed of a warm, shallow ocean that existed long before humans appeared. The fossils you find — ammonites, fish, and reptiles — are the remains of creatures that lived and died there. As the sea floor turned to stone and was later lifted by geological forces, those layers became the cliffs we see today. Walking the beaches here really is like walking across an ancient ocean floor.
9. The Jurassic Coast Is Still Being Discovered
Scientists continue to study the Jurassic Coast, and new discoveries are made all the time. Recent finds have included a near-complete ichthyosaur skeleton and a giant ammonite almost one metre wide. Local museums and fossil shops in Lyme Regis often showcase new specimens, and visiting them adds another layer to the experience — helping visitors understand how geology and discovery are still unfolding right now.
10. You Don’t Need to Be a Scientist to Appreciate It
Perhaps the best fact of all: you don’t need to know anything about geology to enjoy the Jurassic Coast. Whether you’re beachcombing, photographing the cliffs, or simply watching the tides change colour against the rocks, the sense of deep time and natural wonder is easy to feel. It’s this combination of beauty and history that keeps Lyme Regis so endlessly fascinating — and why the Jurassic Coast continues to inspire everyone who visits.
Bringing It All Together
Lyme Regis isn’t just another seaside town — it’s a gateway to Earth’s ancient past. The Jurassic Coast offers a living classroom for anyone curious about how the world was shaped, and the town’s mix of heritage, scenery, and community makes it the perfect base for exploring it all. Whether you’re here to find fossils, follow in Mary Anning’s footsteps, or simply take in the view, every visit adds a new story to your own Jurassic journey.
