AMMONITE FREE FORM WITH BASE
An ammonite is a type of fossilized sea creature that belongs to the class Cephalopoda, which also includes modern-day animals such as squids, octopuses, and nautiluses. Ammonites were marine mollusks that lived in the sea during the Mesozoic era, from about 252 to 66 million years ago. They were characterized by their coiled shells, which were divided into chambers separated by thin walls called septa.
Ammonites were abundant during the Jurassic and Cretaceous periods and are found in many locations around the world. Their shells were often preserved in sedimentary rocks, and as the shells fossilized, they became transformed into a hard, mineralized material called calcite.
Ammonites are popular fossils among collectors because of their distinctive shape and the wide range of sizes and patterns that are found in their shells. They are also important to scientists because they can be used to study the geology and paleontology of the Mesozoic era, including the evolution of marine ecosystems and the changing climates of the time.
