Ammonite Euhoploceras (sonninia) modestum

The ammonite from the genus Euhoploceras from the south coast of England will delight any fossil connoisseur. The shell of the ammonite is slender, disk-shaped, placed on a natural stone matrix. What draws attention is the front edge of the shell, which was once in contact with the living cell of the shell. The protrusion, which resembles a plant leaf, is a lobed line, cleaned and free of mineral deposits. This line is the edge of the internal partition, which has a very complex shape. Such partitions are located inside the whole spiral of the shell, giving it greater strength. From the outside, the joints between the partitions and the shell walls look like a plant ornament.
