Orthoceris had a straight shell and existed from the Lower Ordovician
through Upper Triassic - 400 Million Years to about 200 Million years.
The Ammonite, or Ammonoidea, had a tightly coiled shells, and many are
ornamented with ribs, bumps, and spines. The Ammonite existed from the
Devonian through Cretaceous - 395 Million Years to about 100 Million
Years. Living cephalopods include the squids, cuttlefish, octopods, and
nautilus. In these fossils, what you see is the fossilized outer shell of
the animal.
