Fossil hunting: a quick guide
We go fossil hunting on the Isle of Wight!
Fossil hunters have been flocking to the Isle of Wight since the 1850s. And it’s easy to see why – the Isle of Wight is simply the best place in the UK to go fossil hunting and discover dinosaur remains. So much so, that it’s been lovingly labelled ‘Dinosaur island‘!
The Isle of Wight’s beaches are littered with countless fossils from the Lower Cretaceous period – so a fossil hunting visit to the island is like peering 125 million years back into the past, to a time when giant dinosaurs roamed the Earth. Roooar-some!
What makes the Isle of Wight special for fossil hunting?
The Isle of Wight wasn’t always where it is today. 125 million years ago the Earth looked very different, and the island was much further south – at roughly the latitude of North Africa. Because of this, temperatures on the island were much warmer and it formed part of a subtropical river valley complex. A diverse range of creatures like crocodiles, fish, reptiles and mammals called this swampy and leafy land their home!
In fact, the island is bursting with so many fab fossils that in 2009, a 5-year-old girl named Daisy Morris discovered a brand new species of pterosaur (a type of flying lizard) from bones sticking out of the sand. Scientists named the winged creature Vectidraco daisymorrisae in honour of her. How cool is that?

What do I need?
Clothes – Comfortable clothes and walking shoes are a good idea, as you may need to clamber over some rocks to spot dino footprints. Beaches can be quite exposed to the elements, so make sure to pack sunscreen and a cap to protect yourself the sun, and a lightweight jacket that’ll keep you warm if the temperature suddenly drops.
Kit – Keep kit to a minimum! Try to avoid using things like chisels and picks. Sometimes amateur fossil hunters will hammer away at rocks and unknowingly causing damage a dinosaur fossil. Chipping away at the bottom of cliffs could put you in danger of rock falls, too. It’s also illegal to dig fossils out of the cliffs without the landowner’s permission, so avoid taking a shovel.
What do I look for?
Fossilised wood – Keep an eye out for the charred remains of ancient trees. These look like black lumps of coal. Excitingly, these often appear to be laced with gold, but it’s actually a similar looking mineral called iron pyrites.
Fossilised shells – Ancient Isle of Wight was covered in swamps, rivers and ponds. Along the beach, you’ll spot the fossilised remains of many water-dwelling creatures that lived during this time embedded in the clay or rock. You might find sea urchins, mussels, oysters, ammonites, corals, sponges, and more!
Dinosaur bones – Often dinosaur bones tumble out of the cliffs, into the sea and eventually wash up on the beach. Usually black or brown in colour, the best way to spot them is the look for a honeycomb structure. This is where the bone marrow has been filled with minerals over time.
What do I do if I find something?
If you find a small fossil on the beach, feel free to pick it up and take it away! However, larger fossils shouldn’t be moved from their location, as they may get damaged. If you feel like you you’ve found something important, get in touch with Dinosaur Expeditions Centre, the Island’s fossil museum. They will be able to advise you on your find!
Which dinosaur fossils might I spot?
Over 20 different types of dinosaur have been found on the Isle of Wight. Here are three of our favourites!
The distinct footprints of this huge herbivore are easy to spot on beaches of the Isle of Wight. These big plant-munching dinosaurs mostly moved around on all fours but could run on two legs when needed. The iguanodon stood at around 10 metres tall and weighed about the same as an African elephant!
The polacanthus was a bit like an armoured sheep! The plant-chomping dinosaur was very distinct-looking, with scary looking spikes running down its back to help protect it from predators. In fact, its name literally means ‘many spines’.
The Baryonyx was a fearsome looking meat-eater had a head that looked a little bit like a crocodile. The Baryonyx would likely have crouched on river banks hooking fish with its enormous 30cm-long-claws.
