This vintage prehistoric Halloween t-shirt combines spooky seasonal style with natural history, featuring a roaring Tyrannosaurus rex beneath a carved jack-o'-lantern in a dramatic retro illustration. The distressed design uses bold orange, black, and warm autumn tones to create a classic fossil-inspired Halloween look, celebrating the Late Cretaceous Period and one of Earth’s most iconic dinosaurs. Made from 100% ring-spun cotton (high-quality cotton) with a soft, sensory-friendly feel. Every order funds kelp restoration on the Pacific Northwest coast.
