18" Jurassic Ammonite and Belemnite Cluster - England

Jurassic Ammonite and Belemnite Cluster - England #279471

This is a gorgeous, 18" wide, natural association of ammonites (Parkinsonia rarecosta) and belemnites collected from Dorset, England. They are Jurassic (Bajocian Stage) in age, or approximately 168 million years old. All have been nicely exposed from the rock they were found in. The largest ammonite measures 6.2" wide.

This specimen is accompanied by a metal display stand to assist with presentation.

Ammonites were predatory cephalopod mollusks that resembled squids with spiral shells. They are more closely related to living octopuses, though their shells resemble that of nautilus species. True ammonites appeared in the fossil record about 240 million years ago during the Triassic Period. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
