Doolysaurus

Jung et al. 2026

Doolysaurus is an extinct genus of thescelosaurid ornithischian dinosaur known from the Cretaceous Ilseongsan Formation of South Korea. The genus contains a single species, Doolysaurus huhmini, known from the partial skeleton of a small juvenile individual. It is the first named South Korean dinosaur with diagnostic cranial material, providing important insight into the early evolution of thescelosaurid ornithischians in East Asia, and the second named basal neornithischian from South Korea after Koreanosaurus.

Scientists found a baby dinosaur hidden in rock and it is surprisingly cute
bone drawing South Korea Dinosauria Doolysaurus +3
Scientists uncovered a rare baby dinosaur in South Korea and named it Doolysaurus after a famous cartoon character. Using cutting-edge CT scans, they discovered hidden bones—including a skull—inside rock much faster than traditional methods. The young dinosaur, possibly fluffy and lamb-like, even had stomach stones that reveal it ate a mix of plants and small animals. The discovery suggests many more dinosaurs may still be hidden in Korea’s rocks.
