They can be separated into 3 categories: the Nautiloidea (chambered Nautilus), the Ammonoidea (the extinction ammonites), and also the Dibranchiata (squids, the die out belemnites, and octopuses).

Ammonite fossils take place in locations in the Cretaceous of Delaware. One ammonite have the right to be thought of as an octopus stuffed within a straight, coiled, or spiral shell. They space uncommon finds at the C & D Canal, commonly occuring as broken pieces; a complete one is a rare and also exciting find. Most of the bigger coiled people are discovered in the Merchantville Formation. Sections of the straight-shelled Baculites are much more common in the mountain Laurel Formation.

The belemnite varieties Belemnitella americana is the Delaware State Fossil. They room amber colored, bullet-shaped fossils that offered as the internal skeleton in an die out squid-like animal called a belemnoid. Belemnites are a common find top top the mount Laurel spoils pile since they probably traveled in huge schools.
