Ammonite Lytoceras sp.

The magnificent ammonite Lytoceras looks like a piece of jewelry from the god of the sea, Poseidon. In spite of its somewhat massive shell, these cephalopods were excellent swimmers and hunted in the water column for a long time, from the Jurassic to the Cretaceous periods.

The large, heavy whorls of the shell carry a pattern of light cross sections and tree-like lobed lines. The color of the shell varies harmoniously from brown to olive colors. If you turn the ammonite shell at a certain angle to the source of light, its surface will brighten with rainbow iridescence.
