Here is a limestone rock that we found in a loose shale slab and extracted using our larger tools before opening it up on the beach with our geology hammer 🏝🌊 The surrounding shale is softer than the limestone and is easily removed. Inside was a beautiful Dactylioceras tenuicostatum ammonite fossil from the Jurassic 😳 This ammonite is around 185 Million Years Old 💀 If you would like an ammonite rock to crack open, please message us directly on yorkshire fossils or visit our website yorkshire
