A belemnite fossil sculpted as a long bullet-shaped guard with its chambered end cut open to show the inner structure. The smooth rostrum tapers to a sharp point and carries faint lengthwise growth lines, while the upper section opens into a ribbed phragmocone with stacked chamber walls and a small siphuncle opening on one side. Weathered stone detail gives it the look of a real specimen pulled from rock. It suits a fossil collection shelf, a paleontology lesson in the classroom, or a natural history display beside ammonites and trilobites.
