Description:

Western Europe, France, Lyon, Jurassic period, ca. 184 to 175 million years ago. A striking sculptural cluster of ammonite fossils, likely of the genus Hammatoceras, preserved in a natural stone matrix. The composition rises in a tiered formation, with a prominent upper ammonite displayed in almost fully freed from the surrounding stone. Below and around it, several additional specimens - ranging from nearly complete to partial - remain embedded within the matrix, creating a layered and visually dynamic arrangement suggestive of their original depositional context.
