Phacops Trilobites are extinct marine arthropods that lived in ancient oceans millions of years ago. They are one of the most well-known types of trilobites because of their distinctive appearance and well-preserved fossils.
Parts of a Phacops Trilobite:
- Cephalon (Head): The front section containing the eyes, mouth, and facial features.
- Thorax: The middle section made up of multiple articulated segments that allowed the trilobite to move and curl up for protection.
- Pygidium (Tail): The rear section formed by fused segments, creating the trilobite's tail shield.
Compound Eyes: Large, well-developed eyes composed of many individual lenses. - Exoskeleton: A hard outer shell that protects the trilobite and is commonly preserved as a fossil.
