Trilobite fossil. Fossil of a quadrops trilobite (Flexuosa sp.) showing the animal's many spines. Trilobites are extinct hard-shelled, segmented arthropods that lived in ancient seas. They are considered one of Earth's earliest, complex life-forms and are one of the most well-known creatures of the Palaeozoic Era. Trilobites existed between the Cambrian and Permian periods around 542-250 million years ago, and were mainly bottom-feeding, scavengers.
