$5.95 Shipping Condition: Unspecified Location: Tucson, United States Hi there. I am selling this really amazing Elrathia trilobite fossil. It inhabited the ocean floor in what is now Utah, in the United States about 500 ... moremillion years ago. I bought it at a gem show in Arizona and it was found in the Wheeler Shale, Utah. Trilobites are extinct marine arthropods. They existed for 270 million years, from 520 to 250 million years ago. This makes them one of the most successful of all early animals, with 17,000 known species. The trilobites survived several extinction events but finally disappeared from the fossil record shortly before the Great Permian Extinction; Earth's most severe mass extinction event, where 96% of all marine species went extinct. If you have any questions, do not hesitate to ask me. Thanks so much for visiting my store!.
