Polished Stone Tabletop – Ammonite Shell Fossils (Auction 2026-06-05, Lot 142)

$578.25

North Africa, Morocco, Devonian Period, ca. 419.2 to 358.9 million years ago. Polished to a lustrous and smooth surface, this circular stone tabletop slab reveals a cross-section of ancient seafloor life – a dense, naturally occurring mosaic of Orthoceras and ammonite fossils locked in dark limestone matrix. Pale spiral ammonite chambers and the long, tapered cylinders of Orthoceras shells emerge in dramatic contrast against the mottled, gray, brown, and black stone. The slab is finished with a smooth beveled edge that lends the piece a clean architectural profile, making it equally at home as a functional table surface or a standalone sculptural object. Size: 24″ Diameter x 0.5″ W (61 cm x 1.3 cm)

Provenance: private Colorado, USA collection
