2.2" Fossil Ammonite (Pachydiscus) - Alaska

This is a 2.2" ammonite (Pachydiscus) from the Kaguyak Formation of Alaska. It is in good condition. Some of the inner shell remains showing the intricate suture lines. It is from an old collection and has a painted label.

This ammonite comes out of an old fossil collection we recently purchased with a lot of unique material from unusual and often no longer accessible sites.

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.
