Lot description
Polished ammonite seabed fossils in natural Moroccan upright sculptural stone slab. Ammonites are extinct members of the Cephalopod class. Modern members include nautilus squid and octopus. They first appeared during the Silurian Period (435 million to 410 million years ago) and were abundant and widespread in the seas of the Jurassic and Cretaceous periods (175 million to 65 million years ago). Ammonites are important index fossils. They often link the rock layer in which they are found to specific geological time periods. This is a carved and polished Moroccan fossil plaque. It is essentially huge piece of rock pulled from a dry seabed and then hand polished. 25 1/2"H x 21"W.
