4.2" Fossil Ammonites (Aegocrioceras) on Rock - Germany

Fossil Ammonites (Aegocrioceras) on Rock - Germany #77950

This is a pair of unusual Aegocrioceras ammonites collected near Groß Resse, Germany. There are a few crack repairs and some minor gap fill restoration on the specimen. The center ammonite on what could be considered the front of the rock is 4.2" wide, with a 1.4" wide ammonite sitting adjacent to the center ammonite. The back side of the rock also features an ammonite that measures 3.7" wide.

The rock that these ammonites are on is 7" x 6.3".

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.
