Ammonite fossil, Lytoceras sp., from Madagascar, Cretaceous lower (approximately 145–100.5 million years ago), natural condition, weight 20.5 kg, dimensions 400 × 330 × 140 mm.
Description from the seller
The ammonite fossil belongs to the species Lytoceras, originating from Madagascar. This ammonite dates back to the Jurassic period, approximately 150-160 million years ago, when dinosaurs dominated the land and the first flowering plants began to appear.
Madagascar, during the Jurassic period, was part of the supercontinent Gondwana. The region was characterized by a tropical climate and hosted a wide range of marine habitats. The ideal conditions for fossilization, including limestone-rich sediments and low tectonic activity, allowed for the exceptional preservation of these fossils. The Lytoceras was found in shallow marine waters, where it thrived by feeding on small planktonic organisms and utilizing ocean currents for movement.
