Ammonites & Nautilus for Sale

Ammonites are an extinct group of marine cephalopods with a coiled external shell that appeared during the Devonian period and into the Cretaceous period 240-65 million years ago. This was about the same time as dinosaurs disappeared so ammonites are valuable in dating rocks. Fossils were formed when the remains of ammonites became covered in sediment, which later hardened into rock.

Ammonites were predators and were related to octopus, cuttlefish and nautilus. Nautilus, which date back to the Cambrian period, have lived unchanged for millions of years.

They lived in open water and moved by jet propulsion. The ammonite’s shell was divided into separate chambers. The smaller chambers were filled with gas which maintained their buoyancy. On the shell there is a suture line, which is a narrow, wavy line which are important for identifying species.
