20 rock samplesarranged stratigraphicallySpecimens: 60 x 90 mmsorted into collection boxes, delivered in a wooden case.Typical rocks from all geological formations reveal the evolutionaryhistory of our planet. They document periods of increased volcanic or tectonicactivity, extensive marine areas or large landmasses, climatic changes,and tell the story of how life spread across the Earth.The specimens are labeled with tags indicating the exact name, age,and locality. A protective film covers each label to prevent scratching.The rocks are numbered so they can be easily re-identifiedin case one is misplaced. This series of rocks comes in system-bloccollection boxes, which are arranged in a wooden case.A detailed list of contents is included with each collection.Our collections are handcrafted in-house.Please note that rocks are natural products and no two piecesare ever exactly alike.Due to technical limitations, the colors on your screen may differ from those of the original pieces.Our images are for illustrative purposes; upon purchase, you will receive a collection of equivalent quality.
