Beautiful, 3.65" Ammonite (Arnioceras) Fossil - England

This is a 3.65" wide, Lower Jurassic ammonite (Arnioceras sp.), collected from the Lower Lias stratigraphic layer in Dorset, England. There is one extremely well-preserved ammonite on the specimen which was expertly prepared from the hard limestone. A second, smaller, unidentified ammonite rests on the shell of the Arnioceras.

It comes with an acrylic display stand.

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.
