A beginner's guide to fossil hunting on rocky beaches

There is a particular kind of magic in walking a rocky beach at low tide, eyes scanning the ground for something that has not seen daylight for millions of years. The UK’s coastline is a treasure trove for fossil hunters, from the Jurassic shales of Dorset to the coal measures of Yorkshire and the ancient sediments of Scotland. You do not need to be a geologist to start. You just need patience, a good eye, and a respect for the fragile places where these relics rest.

Where to look: reading the rocks and the tide

Fossils are most likely to appear where erosion is active. Look for stretches of beach with fallen boulders, scree slopes, and loose pebbles below cliffs. These are the places where the sea is slowly wearing away the rock, freeing fossils that have been locked inside for millennia. After a storm is often the best time, as fresh material is washed out and scattered across the shore.

Before you go, check a tide table. The best window is the two to three hours either side of low tide, and always on a falling tide. Rocky beaches can be cut off quickly, and cliffs are unstable. Never hammer into the base of a cliff or a bedrock platform; that damages the site and is dangerous. Instead, search among loose stones and shingle. Turn over rocks carefully, and always put them back as you found them.

Some classic beginner spots include the beaches around Charmouth and Lyme Regis in Dorset, Robin Hood’s Bay and Whitby in Yorkshire, and the coasts of Skye and the Isle of Wight. But you do not need a famous name. Any rocky beach with exposed sedimentary layers is worth a look.

What to bring: a simple, low-impact kit

You can start with very little. The goal is to observe and collect responsibly, not to quarry the beach. For most beginners, a hammer and chisel are unnecessary and can cause damage. If you do plan to use them, check local rules first, and always wear eye protection and sturdy gloves.

• Soft brush – a paintbrush or nail brush for gently clearing sand and mud.
• Hand lens – a 10x magnifier helps you see fine details like shell patterns or tiny teeth.
• Notebook and pencil – for recording where and when you found something.
• Small bags or newspaper – for wrapping fragile finds. Bubble wrap is useful for delicate specimens.
• Sturdy boots – rocky beaches are slippery. Wellies or walking boots with good grip are essential.
• Tide table and map – paper or a downloaded version on your phone. Do not rely on signal.
• Phone or camera – for photographing finds in place before you move them.

Dress for the weather. Coastal winds can be biting even on sunny days, and a waterproof layer is always wise. Take water and a snack, and tell someone where you are going.

How to spot a fossil: common finds for beginners

Ammonites are the classic starter fossil: spiral shells that look like tightly coiled snakes. You will often find them as flat impressions or as solid, ridged stones. Belemnites are bullet-shaped and were once part of a squid-like creature. Bivalves and brachiopods look like modern cockles or scallops, but with a stony weight and a different symmetry. Crinoids, or sea lilies, appear as small discs or star shapes. Shark teeth are rare but unmistakable: glossy, black, and triangular with a sharp edge.

The trick is to look for regular patterns. Nature makes many shapes, but fossils often have symmetry, repeating segments, or a texture that is too organised to be random. Wet the surface of a suspect rock with a little water or spit; details pop out. Do not be disheartened if you find only fragments. A single ammonite whorl or a piece of crinoid stem is still a wonderful thing.

Recording your finds: the responsible way

A fossil without a location is just a curious stone. Before you pick anything up, take a photograph of it in place. Note the grid reference, the date, and what you saw around it. A simple notebook is fine, but a phone app that records coordinates works too. If you find something fragile, wrap it carefully and do not clean it aggressively. Mud can be brushed away, but scrubbing can scratch or break delicate structures.

When you get home, label your find with the location and date. Keep a small card with each specimen. If you later decide to donate it to a museum or a local geological group, that information makes it scientifically useful. Never collect from protected sites without permission, and never take more than a few pieces. The beach is not a quarry; it is a shared landscape.

Protecting fragile habitats: leave no trace

Many rocky beaches are Sites of Special Scientific Interest (SSSIs) or nature reserves. They are home to nesting birds, seals, and rare plants. Stay away from cliff edges and do not disturb wildlife. If you move rocks, put them back. Fill any holes you dig. Take all your litter home, including any broken pieces of fossil you decide not to keep.

Most importantly, follow local rules. Some beaches ban hammering entirely; others allow it only in certain areas. If in doubt, ask a local museum or a geologist. The best fossil hunters are the ones who leave the beach as they found it, so that others can enjoy the same thrill of discovery. With a little care, you can bring home a piece of deep time and a memory of a wild, windswept coast.
