Scientists found a baby dinosaur hidden in rock and it is surprisingly cute
bone drawing South Korea Dinosauria Doolysaurus CT-scan discovery skull
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.

Triceratops had a giant nose that may have cooled its massive head
fossil Triceratops CT-scan skull
Triceratops’ massive head may have been doing more than just showing off those famous horns. Using CT scans and 3D reconstructions of fossil skulls, researchers uncovered a surprisingly complex nasal system hidden inside its enormous snout. Instead of being just a supersized nose for smelling, it likely housed intricate networks of nerves and blood vessels—and even special structures that helped regulate heat and moisture.
