Berlin-Ichthyosaur State Park contains a town built in the 1890s that is preserved in a state of arrested decay. A true Nevada ghost town, many of Berlin’s original buildings remain and some of its original residents are interred in the town’s cemetery. Trails throughout the town site tell the story of Berlin and its mine. The park is also home to the most abundant concentration, and largest known remains, of Ichthyosaurs, an ancient marine reptile that swam in a warm ocean that covered central Nevada 225 million years ago. The fossils are protected and displayed at the park’s Fossil House.
