Celebrate one of the most iconic dome-headed dinosaurs with our Pachycephalosaurus Born to Bonk T-Shirt. Featuring a bold vintage-style graphic of two Pachycephalosaurus squaring off, this design pays homage to the “thick-headed lizard” that lived about 72 million years ago during the Late Cretaceous. Known for their distinctive domed skulls, these herbivores are believed to have engaged in head-butting contests — a prehistoric display of strength and dominance.

The distressed retro typography and natural earth-tone print give this tee a timeless, vintage appeal perfect for paleontology fans, dino enthusiasts, and natural history collectors.

Crafted from 100% ring-spun cotton, this shirt is sensory-friendly, soft, and eco-conscious. Every order funds kelp restoration on the Pacific Northwest coast. Wear your love for science, sustainability, and prehistoric power with pride.
