2.7" Polished Fossil Ammonite (Dactylioceras) Half - England

Polished Fossil Ammonite (Dactylioceras) Half - England #240744

This is a classic English ammonite of the species Dactylioceras commune. These well preserved ammonites are Jurassic in age and are found in hard concretions that must be split open to reveal the fossil. This pyritized nodule has been cut in half and completely polished, exposing the inner detail of these beautiful ammonite fossils. The base of the nodule has been cut flat, creating a perfect fossiliferous paperweight.

Comes with an acrylic display stand.

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.
