Rare Rachiphyllites sp. Ammonite – Timor, Indonesia This exceptional ammonite, attributed to Rachiphyllites sp., originates from the fossil-rich region of Timor, Indonesia. Specimens of this genus are uncommon on the market, making this piece particularly desirable for collectors. Expertly cut and polished on one side, the fossil reveals a beautiful arrangement of internal chambers, many of which are filled with crystal formations that add brightness and depth. The natural suture lines and the spiral geometry are clearly visible and create a striking visual effect. The reverse side remains unpolished, preserving the fossil’s authentic texture and geological character — a fascinating contrast between natural preservation and prepared display. A rare and unusual ammonite, ideal for advanced collectors, museums, or anyone seeking an eye-catching and scientifically interesting decorative specimen. Includes a clear acrylic stand for elegant display.
