Historical Illustration of Two Dolphin Species - Delphinus superciliosus & Delphinus cruciger #2061973 (License: Personal Use)

This hand-colored lithograph from the early 19th century illustrates two cetacean species: the white-sided dolphin (Delphinus superciliosus, now reclassified as Lagenorhynchus acutus) and the hourglass dolphin (Delphinus cruciger, now Lagenorhynchus cruciger). The image features precise anatomical rendering, including dorsal fin shape, flank markings, and ventral coloration, typical of pre-modern marine mammal taxonomy. Published by Pourrat in Paris, it reflects the era’s emphasis on visual documentation for scientific classification.

Used in educational or historical contexts-museum exhibits, academic articles on cetacean taxonomy, or digital archives of natural history illustrations. Targets users researching marine biology history, vintage scientific art, or dolphin evolution and classification.
