Rare and striking Acanthoceras heteromorph spiral ammonite fossil display specimen with a dramatic coiled “ram-horn” form, pronounced ribbing, and strong sculptural presence. The fossil is naturally presented on a pale stone matrix base, making it an excellent collector specimen, natural-history display piece, or cabinet-of-curiosities centerpiece.
The specimen features dark brown to charcoal tones with visible ridging, natural surface texture, mineral variation, and excellent visual contrast against the lighter matrix. Its unusual spiraled form gives it a distinctive architectural look and makes it stand out from more common flat ammonite specimens.
