Craspedodiscus discofalcatus, a Late Jurassic specimen from Ulyanovsk, Russia, with a complete spiral and excellent preservation, professionally polished surface to enhance the color play, weighing 5870 g and measuring 295 × 255 × 70 mm.
Description from the seller
Rare and precious specimen of Craspedodiscus discofalcatus, originating from the famous paleontological area of Ulyanovsk, along the banks of the Volga (Russia).
This is a species from the Upper Jurassic, known among collectors for the very rare possibility of exhibiting opalization phenomena. In this specimen, the red opalescence is particularly intense and widespread, with large areas that react to light, producing red, orange, and gold reflections.
The optical effect is due to the transformation of the original aragonite lamellae, which in some cases are preserved in microstructures capable of diffracting light, generating the characteristic 'ammonite-like' luminescence.
Specimens of Craspedodiscus with a similar quality of opalescence are extremely rare and highly sought after on the international collector's market.
The conservation is excellent: the spiral is complete, the internal chambers are legible, and the surface has been professionally polished to enhance the play of colors to the fullest.
A piece of great presence, ideal for both collectors specializing in Russian ammonites and collectors of aesthetic and valuable fossils.
