Description
This listing features a genuine and well-preserved specimen of Euaspidoceras jeanneti, an extinct genus of ammonite from the Middle Oxfordian stage of the Jurassic Period (~163 to 157 million years ago). This impressive fossil was discovered in Sakahara, Madagascar, a location renowned for its rich and diverse Jurassic marine deposits.
Euaspidoceras belongs to the family Aspidoceratidae and is known for its robust, thick shells with distinctive ribbing and a rounded, involute coiling style. These ammonites were nektonic carnivores, free-swimming in warm Jurassic seas. Their fossilised remains help scientists reconstruct the biodiversity and environmental conditions of Late Jurassic marine ecosystems.
