6.7" Free-Standing Fossil Ammonite (Hammatoceras) Pair - France
This is a beautiful display piece featuring a pair of Hammatoceras ammonites from Belmont, France. It measures 6.7" tall and the base of stone has been cut flat so that is displays nicely on a hard surface without the need for a display stand. These ammonite fossils are Lower Jurassic (Toarcian Stage) in age, or around 180 million years old.
Ammonites were predatory mollusks that resembled a squid with a shell. These cephalopods had eyes, tentacles, and spiral shells. They are more closely related to a living octopus, though the shells resemble that of a nautilus. True ammonites appeared in the fossil record about 240 million years ago. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
