The Cincinnati Museum Center has opened a new permanent exhibit called "Ancient Worlds Hiding in Plain Sight," which showcases the geologic riches of the Cincinnati region. The exhibit spans the majority of the Paleozoic Era, from the Ordovician Period to the Carboniferous Period, and features over 400 specimens, including fossils of trilobites, brachiopods, and corals. The gallery aims to connect the study of deep time with current issues such as climate change and evolution. The exhibit also includes interactive elements, such as hands-on displays and a life-sized image of an Ordovician hardground. The gallery is a collaboration between the Cincinnati Museum Center and local amateur collectors, and it aims to educate visitors, inspire future scientists, and foster a connection to the natural world.
