Scientists Find Dinosaur Covered in Never-Before-Seen Spikes

Picture a plant-munching dinosaur that rolled out of the Early Cretaceous looking like it lost a bet with a porcupine: meet Haolong dongi, the newly discovered Chinese dino sporting hollow, skin-based spikes never seen before in the fossil record. This 125-million-year-old juvenile was so perfectly preserved that scientists could peek at individual cells, revealing these punk-rock protrusions weren’t bony but dermal defenses—perhaps to scare off theropods, regulate heat, or just look extra intimidating. Named after a legendary paleontologist, H. dongi proves nature’s been experimenting with edgy fashion for eons.
