The state of Ohio boasts some truly world-class fossil locales including the Arnheim formation near Mount Orab. This site is as famous for its incredible preservation as it is for the prolific volume of specimens one can find here. These trilobites are often prepared commercially at great speed for the quick n' dirty fossil market. If you are reading this, you know that we don't do that here. These trilobites have been prepared with care under high magnification and using soft blast media. These specimens come from the Flat Run fossils quarry, a pay-to-dig site with affordable daily rates and quality operators. Check them out if you're near Ohio!
