Ammonite fossils are the preserved remains of extinct marine mollusks that lived during the Mesozoic era, approximately 240 to 66 million years ago. These creatures had coiled, spiral shells divided into chambers, which they used for buoyancy control. Ammonites are well-known for their intricate suture patterns, which are the lines where the walls of the chambers met the outer shell. These fossils are significant in geology and paleontology as index fossils, helping scientists date and correlate the age of rock layers.
