Description
Offered here is an authentic and visually striking Aspidoceras rogozniziense fossil ammonite, from the Kimmeridgian stage of the Late Jurassic (~157 to 152 million years ago). This fossil was unearthed in the famous fossil-rich beds near Tulear, Madagascar, a region renowned for its abundance of well-preserved marine fossils.
Aspidoceras is a genus of large ammonites within the family Aspidoceratidae. These ammonites are known for their thick shells and pronounced ribbing, often with tubercles (knob-like projections), giving them a distinctive appearance. As nektonic carnivores, they were active swimmers in the ancient seas that once covered Madagascar.
This specimen is a superb example of the genus, showcasing its robust form and shell detail. It has been carefully selected and prepared to display its natural beauty and palaeontological significance. The fossil shown in the photo is the exact one you will receive, and the 1cm scale cube included gives a clear reference for size.
