Rang a giant bell with its head. An extinction event of its own making. The real Pachycephalosaurus (say it pak-ee-SEF-ah-loh-SORE-us) lived in the Late Cretaceous — its skull dome was up to ten inches of solid bone. From Extinction Fails: wordless black-ink skeleton comedy, drawn as pure vectors so even the six-inch print keeps every line crisp. Printed to order on thick matte vinyl, laminated, waterproof and dishwasher-safe, and die-cut to the silhouette with a clean white edge.
