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.

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. Ammonites appeared in the fossil record about 240 million years ago and they barely survived several major extinction events. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
