A beginner's guide to open sea swimming
An easy to read guide to open sea swimming
Most children love dinosaurs - but few will realise that you can find them outside a museum
Guest post by Phil Davidson, Geological Warden of Charmouth Heritage Coast Centre
Everyone, at some point in their lives, has been fascinated in fossils and dinosaurs, but not many people realise that many of England’s beaches are bursting with fossils. With a bit of knowledge and luck you can discover your own fossil and be the first person to have ever seen it!
Some of the most famous fossil beaches in England are on The Jurassic Coast in East Devon and Dorset, the Isle of Wight and the east Coast of Yorkshire. It is always worth doing your homework before you set out on your fossil adventure. Different beaches have different age rocks and fossils and you can expect to find different things. Knowledge is key, so make sure you know the types of things to look out for so you don’t spend all day looking for the wrong things!
One of the best beaches to find fossils is at Charmouth in Dorset. The cliffs around this coast are the remains of a Jurassic seafloor that was teeming with life 190 million years ago. As these cliffs collapse into the sea and the waves wash against them, fossils are dragged out onto the beaches. Here at Charmouth we find lots of different kinds of fossils, but the most recognisable are the spiral shaped ammonites.
Other fossils that we find here are the remains of Jurassic squid, seashells and small ammonites; all can be found loose among the beach pebbles and gravels. Charmouth is also famous for the skeletons of giant reptiles, the ichthyosaurs and plesiosaurs. The best fossil found here was the most complete skeleton a dinosaur ever found in Britain. It was discovered by a local collector, David Sole, in December 2000. Scelidosaurus was an armoured plant-eating dinosaur that lived on the tropical islands that surrounded Charmouth in the Jurassic.
You can go any time, but the best time of year to go fossil hunting is between November and April. Over the winter months the beaches are churned up by the rough seas and more fossils are revealed. It is the combination of rough seas and high tides that produce the most fossils, but these conditions can also be dangerous (see below). You should ALWAYS go out onto the beach as the tide is going out.
The best tools for fossil hunting are a good pair of eyes, as most of the time the fossils are loose among the stones on the beach. Special geological hammers can be used to gently spit open some of the rocks to reveal fossils, but you need to know exactly which kinds of rocks contain fossils. Always wear safety glasses as small chips of rock can damage your eyes.
Here is a list of some of the equipment:
Again, it is best to do your homework and find some information about the fossils that are local to the beach you plan to visit. It is very important to only collect what you need. Some fossils are best left where they are for others to enjoy. Some places (Sites of Special Scientific Interest) are protected by law, so you can go and look but must not collect from them. Sometimes taking a photograph is the best way to take the fossil home with you.
If you find something unusual or interesting it is always worth getting an expert’s opinion. Take the fossil into a local museum or heritage centre where it can be properly looked at and if it turns out to be something of scientific interest you could make the news headlines!
Here on the Jurassic Coast we have a fossil collecting code. All we wish to do is know what scientifically important specimens are found and make a record of the find. You still get to keep the fossil, but we notify the world experts about your find so that they may contact you if they want to study the specimen.
We want to encourage people to collect the loose material on the beach, because if no one collected these fossils they would be destroyed by the sea.

If it is your first time fossil hunting it is always a good idea to join an organised guided walk. These are a great introduction to fossils and can show you not only what to look for, but where the best things are found.
The Charmouth Heritage Coast Centre is an independent educational charity that runs guided fossil walks all year round. For more information about our events please visit our website.
