Elrathia kingii trilobite. Location: Wheeler shale (House range), Millard County, Utah, USA. Period: Middle Cambrian Age: 520million years approx. Size: 21.5x17.5mm (1inch=25.4mm) Supplied with label and display box (fossil and label are easily removable). The term Trilobite refers to an extinct class of arthropods. The word trilobite (Tri-lobeite) alludes to the three-part, longitudinal division of their exoskeleton. These animals first appeared at the beginning of the Cambrian Period around 570 million years ago and were primarily bottom dwellers. They flourished throughout the early Paleozoic Era then decreased in diversity until their extinction in the late Permian Period around 240 million years ago. Fossilized remains of trilobites have been found on every continent. Scientists use Trilobites as stratigraphic index fossils which help to determine the age of rock formations.
