1.9" Ammonite Aptychus Fossil in Rock - Drügendorf, Germany

This is a fossil aptychus that has been exposed from the rock it was found it. It was collected from the Drügendorf Quarry of Drügendorf, Germany. This is a unique fossil that comes from a part of the body of an ammonite and is known as an aptychus. It's debated as to whether the aptychus is a two part hatch that covered the opening of the ammonite, or a double-plate jaw piece. Originally it was mistaken as a bivalve fossil.

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.
