## Curiosity - Did you know?

In rigorous anatomical nomenclature, the spiked tail of the Stegosaurus is officially called a "thagomizer." Surprisingly, this scientific term was born from a comic strip! In 1982, the brilliant cartoonist Gary Larson published a Far Side panel showing a caveman pointing to the dinosaur's tail during a lecture, stating: "Now this end is called the thagomizer... after the late Thag Simmons." The joke was so popular that paleontologist Ken Carpenter began using the term professionally. Today, the thagomizer is a universally recognized scientific concept.

IMPORTANT - Some statements regarding behavior, coloration, and sensory abilities reflect ongoing scientific hypotheses, not established certainties.
