Description
An exceptional and rare specimen of Cleoniceras morgani, a beautifully preserved fossil ammonite from the Lower Albian Stage of the Early Cretaceous, discovered in the fossil-rich layers of Boeny, Madagascar.
Cleoniceras is one of the most iconic ammonite genera known for its smooth, involute shells and intricate suture patterns. This genus is a hallmark of the Albian marine environments, where it thrived in warm, shallow epicontinental seas.
