Ammonite fossil specimen

Ammonites are extinct marine mollusks that lived during the Mesozoic Era, approximately 240 to 65 million years ago. These cephalopods were related to modern-day nautilus, octopus, and squid, and are characterized by their distinctive spiral shells with chamber divisions called septa. Ammonite fossils are highly valued by paleontologists and fossil collectors for their scientific importance and aesthetic appeal. These specimens provide crucial information about ancient marine ecosystems and are used for dating rock formations. Collectors particularly prize well-preserved specimens with visible suture patterns, original shell material, or those displaying the internal chambers.
