Fossilized shells are mineralized shells left over from ancient Marine organisms that formed over millions of years and provide important information about Earth's history and paleoecology, revealing changes in the ancient environment.

Shell fossils are the remains of ancient Marine organisms, which record the earth's history and environmental changes, provide important information about paleoclimate and ecological evolution, and are important resources for paleontology research.

Shell fossils are a common type of fossil derived from the shells of ancient mollusks. They have undergone deposition and fossilization processes over millions of years

Shell fossils are a precious gift given to human beings by nature, which not only records the evolution of the earth for millions of years, but also provides us with a window to understand paleontology and ancient environment
