Quick Overview

This large, uncoiled, Audouliceras matherioanum, from Russia exudes a purplish iridescent hue on a large portion of its outer shell. We consider this specimen “museum grade” due to the large retention of exterior shell, and the nice, purple play of light, from layers of aragonite which formed during the specimens fossilization process.

Location: Saratov, Volga Region, Russia Time Period: Aptian - Cretaceous - Approx. 120 myo Measurements: ~ 6" tall x 9-1/2" wide x 3" thick Actual Ammonite: ~ 6" tall x 9-1/4" wide x 1-1/2" deep

More Information

Ammonites are an extinct group of marine animals in the Cephalopoda class. They are invertebrates and are more closely related to coleoids (squids, octopus, and cuttlefish) than they were to the chambered nautilus, even though they looked much more similar to the later.

The name Ammonite was derived from "ammonis cornua," translated to mean Horns of Ammon. Ammon was an Egyptian god that was typically depicted wearing ram horns, whose spiraled shape is similar to that of an Ammonite.

Ammonites first appeared in the oceans during the Devonian Period, some 400 million years ago. They died out around 65.5 million years ago along with the dinosaurs.

Unlike more commonly structured (homomorphs) Ammonites, Audouliceras matherioanum Ammonites had uncoiled shells. This body shape made them very poor swimmers. They most likely drifted along in the seas, feeding on plankton, or crawled along the seabed, feeding on slower prey.
