Trilobite fossils. Rock containing a number of trilobite fossils (Ellipsocephalus hoffi) from the middle Cambrian period (about 515 million years ago). Trilobites are extinct hard-shelled, segmented arthropods that lived in the Earth's 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.
