The orthoceras is a fossil that is often found in a black or brown marble-like material. This stone fossil material can be polished to a beautiful finish. The orthoceras creature is an ancestor to the modern day squid. Scientists believe that, like the modern squid, the orthoceras would shoot ink out to scare off predators. To move it would suck water in one end and shoot it out the other, the action being similar to that of a jet engine. The orthoceras lived from 345 million to 395 million years ago.
The ammonite agoniatite has beautiful patterns and coils. The ancient creature would grow and continue to build a shell to cover its soft body parts. The creatures would continue to wrap around themselves numerous times and thus the fossils show the growth of the creature, much like the growth lines on a tree. The agoniatite is a Devonian age variety of ammonite. It is approximately 345 million to 395 million years old. Some believe the fossils show cycles and lifetimes, as the coils never end.
