Ran at a tunnel painted on a rock. It worked for the bird. 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. Black-and-white vector ink in the Extinction Fails style — morbid, deadpan and very satisfying on a laptop lid. Teens and up. Printed to order on thick matte vinyl, laminated, waterproof and dishwasher-safe, and die-cut to the silhouette with a clean white edge.
