16" Tall Fossil Ammonite (Parkinsonia) Association - England

This is an absolutely huge Parkinsonia sp. ammonite association from Dorset England. There are three well-preserved ammonites and a small bivalve prepared within the rock in which they were found. The largest ammonite measures 7" wide and has rather unique coloring.

There are a few repaired cracks in the rock that have been stabilized to maintain the specimen's integrity and longevity. The base has been cut flat for ease of display.

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.
