12/01/2026

An Ammonite is probably the most commonly recognised types of fossils since it being one of the most commonly found types off fossils found especially along England's Jurassic Coast, Yet few people actually know what they are.


An ammonite is an extinct marine mollusc known for its distinctive spiral shell, which is often found as a fossil in sedimentary rocks.  It is closely related to modern squids and octopuses, ammonites lived in ancient oceans from the Devonian to the Cretaceous period. Their beautifully patterned shells make them important index fossils, helping scientists date rock layers and understand Earth’s geological history.
