Ammonite Orthoceras Plaque
Ammonite is an extinct cephalopod that lived aproximately 425 - 65 millions years ago in shallow seas. The oldest ammonites lived in the Devonian period; they went extinct in the end of the Cretaceous, when an asteroid colliding with Earth brought on a global mass extinction. They had a characteristic spirally coiled shell made of calcium carbonate. As a matter of interest, the oldest petrified ammonite shells have been found in Czech republic around Prague.
Orthoceras is an extinct cephalopod that lived 350-400 millions years ago in the shallow seas of the present-day Morocco (in the Erfoud site). The name means straight horn, referring to its characteristic long, straight, conical shell.
About the product: On the plaque there are both fossils of ammonite and orthoceras in earthy brown shades. Polished fossils are left grown in a sedimentary rock. We have now available only bigger plaques over 35 cm. Fossils are sold individually; the price is per 1 piece.
