This beautiful XL cluster of Dactylioceras ammonites comes from the famous Holzmaden region of Germany, known for its incredibly well-preserved Jurassic fossils. The ammonites, with their coiled shells and detailed ribbing, are naturally embedded in fine shale and date back around 180 million years. It’s like holding a piece of ancient seafloor—these once-swimming creatures now frozen in time, offering a stunning glimpse into life in the Early Jurassic seas.
