Trilobite Fossil Illustration - Paleozoic Arthropod Anatomy #295711 (License: Personal Use)

This black-and-white line illustration depicts a classic trilobite fossil in dorsal view, emphasizing its tripartite body structure: the cephalon (head) with prominent glabella and facial sutures, a flexible thorax composed of numerous articulated segments with pleural lobes, and a fused pygidium (tail). Fine details such as the axial lobe, genal spines, and possible eye ridges are rendered with scientific accuracy, reflecting common morphological traits of orders like Phacopida or Asaphida. The style mimics 19th- to early 20th-century paleontological plates used in taxonomic descriptions.

Used in educational websites, museum digital collections, academic publications, and geology/paleontology courses to illustrate trilobite morphology, evolution, and fossil identification. Matches user intent for learning about ancient arthropods, preparing teaching materials, or identifying fossil specimens.
