Genuine Fossil Trilobite - Elrathia Kinghi - 2” x 1 7/8”

You will receive the exact genuine Elrathia Kinghi trilobite specimen pictured. Elrathia kingii is an iconic, small Cambrian-period - approx. 500 million years ago) trilobite - with a smooth, oval-shaped exoskeleton. Found in Utah's Wheeler Shale, this common, bottom-dwelling arthropod had 13 thoracic segments, a small cephalon, and a distinct, wide pygidium. The first appearance of trilobites in the fossil record defines the base of the Atdabanian stage of the Early Cambrian period, and they flourished throughout the lower Paleozoic era before beginning a drawn-out decline to extinction when, during the Devonian, all trilobite orders except the Proetids died out. Trilobites disappeared in the mass extinction at the end of the Permian about 252 million years ago. The trilobites were among the most successful of all early animals, existing in oceans for almost 300 million years. Great fossil collectible or fossil gift.
