Trilobite Anatomy Diagram - Cephalon, Thorax, and Pygidium Explained #295701 (License: Personal Use)

This educational diagram illustrates the classic tripartite body plan of a trilobite fossil, with the cephalon (head shield) bearing eyes and antennae, the flexible thorax composed of articulated segments allowing enrollment, and the pygidium (tail shield) fusing the posterior segments. Each region is clearly labeled in red for easy identification, supporting learning in evolutionary biology and paleontological studies.

Used in educational websites, museum exhibits, and academic resources to teach basic arthropod morphology and fossil identification; matches user intent for quick visual reference or classroom instruction on Paleozoic marine life.
