Specimen approx. size: 6.75" x 2.5" x 1.25"

This concretion reveals a stunning display of small ammonites, including two larger Caenisites brooki and numerous Promicroceras. It has been meticulously prepared to reveal many of the ammonites in high relief.

Ammonoids are a group of extinct marine mollusk animals in the subclass Ammonoidea of the class Cephalopoda. These mollusks, commonly referred to as ammonites, are more closely related to living coleoids (i.e., octopuses, squid, and cuttlefish) than they are to shelled nautiloids such as the living Nautilus species. The earliest ammonites appear during the Devonian, and the last species vanished in the Cretaceous–Paleogene extinction event.
