2.8" Cretaceous Ammonite (Buchiceras) Fossil - Peru

This is a 2.8" wide Buchiceras bilbatum ammonite fossil, collected from Cajamarca, Peru. The rock surrounding this ammonite has almost completely been removed. These ammonites are Upper Cretaceous, Coniacian Stage or approximately 86-90 million years old.

Please note, Peru no longer allows the export of fossils. This ammonite was part of an old collection that we recently purchased with a lot of unique ammonites from around the world.

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.
