Find a wonderful gift with our range of trilobite fossils. These instantly recognisable fossils are between 540 and 250 million years old and make remarkable gifts, ornaments and display pieces. Trilobites were marine arthropods that were once found in every ocean. They had a wide range of subspecies, shapes and lifestyles that made the trilobite one of the most successful creature of its era. Our trilobite fossils range from small individual fossils to attractive fossil plates that make excellent gifts. We also have ammonite fossils and rare dinosaur fossils.
