Trilobite Fossil Anatomy Diagram | Paleontology Educational Resource #3610360 (License: Personal Use)

This black-and-white line drawing depicts the dorsal view of a typical trilobite, an extinct marine arthropod from the Paleozoic era. Key anatomical features include the cephalon (head) with glabella and facial sutures, a multi-segmented thorax allowing enrollment, and a fused pygidium (tail). The illustration emphasizes symmetry and segmentation, crucial for taxonomic identification in paleontological studies.

Used in educational websites, museum exhibits, and academic textbooks to teach fossil morphology and evolutionary biology; serves users seeking visual aids for identifying trilobite species or understanding early arthropod body plans.
