About Ammonites
Ammonites were extinct marine mollusks with coiled, chambered shells, related to modern squid and octopuses. They lived in oceans around the world and are known for their beautiful spiral forms and intricate suture patterns.
How Old Are They?
Ammonites first appeared around 400 million years ago during the Devonian Period and thrived until their extinction around 66 million years ago during the Cretaceous-Paleogene extinction event. Their widespread presence in ancient marine sediments makes them valuable index fossils for dating rock layers.
