Trilobite Fossil Illustration - Paleontological Anatomy Diagram #295700 (License: Personal Use)

This precise line-art illustration depicts a dorsal view of a trilobite fossil, likely from the genus Phacops, emphasizing its characteristic three-lobed body plan: axial lobe flanked by two pleural lobes. Fine hatching renders texture and depth, revealing the articulated thorax, well-defined glabella, and genal spines on the cephalon. The image reflects historical paleontological documentation methods used before modern imaging.

Used in educational resources, museum exhibits, and academic publications to illustrate trilobite morphology; serves users seeking fossil identification, evolutionary biology context, or historical scientific art.
