👉 Petrocodon is a type of fossilized sea snail, known for its unique, highly calcareous and transparent shells that are rich in minerals such as iron, sulfur, and magnesium. This combination of materials creates an incredibly protective shell that protects the snail from external threats such as predators or harsh environments. Petrocodons are thought to have played a crucial role in the evolution of marine life by providing protection against harmful substances like toxins and pathogens.
