During the Jurassic and Cretaceous periods, ammonites lived on Earth. These critters lived on the planet for 140 million years, growing more abundant in the Mesozoic age.
Their tentacles and shells allowed them to float freely in water. They were so tiny that the fossils can only be seen under the right kind of light, and researchers were able to examine them by using high-resolution X-rays and neutrons to create a detailed 3D model of the animal's body.
This model allowed researchers to determine the functions of the muscles and tendons in this critter.
Ammonites are extinct marine cephalopods related to modern octopus and squid.
They formed chambers inside their shells and died out during the Cretaceous period 65 million years ago.These animals were abundant in seas during the Jurassic and Cretaceous periods, and are considered index fossils by scientists.
Some fossils are pyritized, forming an iron-disulfide shell, which is known as fool's gold. Ammonite Fossil are categorized by their shells. Some have a spiral-like shell, a flat spiral, or a helical shell. A few species have been found with a knot-like structure called a Nipponites mirabilis.
Despite their many similarities, scientists still don't know how to identify them, and that's the reason why their fossils are so interesting.
