An extraordinary circular mosaic of Upper Cretaceous ammonites (mainly Cleoniceras) has been meticulously cut, polished, and inlaid into a thin resin disc, creating a seamless 23.3 cm‐diameter plate only 0.5 cm thick. The overlapping spiral patterns, ranging from honeyed amber to smoky gray, are highlighted by occasional pyrite and chalcedony infills that catch the light. Every fossil shows crisp chamber walls and sutures, preserved in remarkable detail. The surface is flawlessly buffed to a glossy finish, with smooth edges and no cracks. Ready to display on an easel or mounted on a wall (mounting hardware not included), this piece combines scientific intrigue with elegant craftsmanship, making it a captivating focal point in any setting.
