Fossils Direct strive to bring to our customers the best available fossils. This is a large and extremely well preserved portion of one of the largest Trilobites to be found in the British Isles. Being so large, researchers think that this Trilobite was a carnivore and could have fed on smaller Trilobites. This Trilobite is one of the world's classic Cambrian fossils and is highly sought after. The specimen is approximately 510 million years old. A choice collectors item.
