New dinosaur named for iconic Korean cartoon character Dooly
- Scientists discovered a new baby dinosaur in South Korea. They named it Doolysaurus, after a beloved Korean cartoon character.
- They scanned the fossil using micro-CT technology, revealing hidden bones and skull parts without disturbing the rock.
- The researchers also found over 40 stomach stones with the bones. These suggest Doolysaurus was an omnivore that ate both plants and small animals.
The small, fuzzy, baby dinosaur may have looked like a lamb
Scientists have discovered the fossils of a rather charming baby dinosaur in South Korea. The researchers from the University of Texas at Austin said on March 19, 2026, that it was an omnivorous, turkey-sized youngster, about two years old. And it ran around on its hind feet. Plus, researchers think it might have had a coat of fuzzy hair-like filaments. They named it Doolysaurus huhmini, after a cute and mischievous green baby dinosaur named Dooly. Dooly is a much-loved character in a South Korean cartoon series.
Jongyun Jung, at the University of Texas at Austin, is the lead author of the new paper. Jung said:
Dooly is one of the very famous, iconic dinosaur characters in Korea. Every generation in Korea knows this character. And our specimen is also a juvenile or ‘baby,’ so it’s perfect for our dinosaur species name to honor Dooly.
Julia Clarke, also at the University of Texas at Austin, is a paper co-author. She added:
I think it would have been pretty cute. It might have looked a bit like a little lamb.
The peer-reviewed journal Fossil Record published the new paper on March 19, 2026.

A high-tech dinosaur reveal
Researchers have found dinosaur tracks and eggs in Korea before, but dinosaur bones have been rare. In fact, Doolysaurus is the first dinosaur described from fossilized bones in South Korea in 15 years. Paper co-author Hyemin Jo found the fossil in 2023 on Aphae Island, located off the southwestern coast of South Korea.
The fossil was a partial skeleton entombed in hard rock. As a result, scientists had to excavate the rock containing the fossils as a block, with bones still buried inside. A fossil preparator will need several years to gently recover the delicate fossils.
But the scientists did not have to wait that long to find out what was hidden in the block. They scanned its interior using micro computed tomography (micro-CT) at the University of Texas at Austin. This technique uses X-rays to probe the rock, revealing three-dimensional images of what lies within it.
The researchers were delighted to see that the micro-CT scans revealed more bones, including parts of the skull. Jung commented:
When we first found the specimen, we saw some leg bones preserved and some vertebrae. We didn’t expect skull parts and so many more bones. There was a fair amount of excitement when we saw what was hidden inside the block.
This was a significant find because it’s the first dinosaur with parts of its skull, including teeth, that scientists have recovered in South Korea.
What we know about Doolysaurus
As previously mentioned, the dinosaur’s genus name, Doolysaurus, celebrates the beloved Korean cartoon dinosaur, Dooly. Meanwhile, its species name, huhmini, honors the prominent Korean paleontologist Min Huh. He founded the Korean Dinosaur Research Center and has studied Korean dinosaurs for more than 30 years.
Scientists found Doolysaurus in rock dating to between 113 million to 94 million years ago, placing the dinosaur in the mid-Cretaceous Period. It was a juvenile, around two years old, when it died. The researchers were able to determine its approximate age by studying growth markers visible in a thin slice of the dinosaur’s femur (thigh bone). It was the size of a turkey and may have weighed just 18 pounds (8.3 kg). Moreover, the scientists think that an adult Doolysaurus could have been double that size.
The bones also placed Doolysaurus in the Thescelosaurid family of dinosaurs. Scientists have found these types of dinosaurs in East Asia and North America; they were bi-pedal and may have had a coat of fuzzy hair-like filaments.
They also found gastroliths
The scientists also found over 40 pebbles among the bones in the block, ranging in size from 1/16th to 4/10th of an inch (2 to 10 mm). These are gastroliths, also called stomach stones. Herbivorous and omnivorous dinosaurs swallowed pebbles to grind food in their digestive tract. (Some living animals, such as crocodiles, alligators, and herbivorous birds, also carry gastroliths.)
The size and shape of the gastroliths they found suggested that Doolysaurus was an omnivore. It likely fed on plants and small animals including insects. In fact, it was the presence of some gastroliths at the surface of the rock that led the scientists to scan the block to look for additional bones.
Clark remarked:
A little cluster of stomach stones, with two leg bones sticking out, indicates that the animal was not fully pulled apart before it has hit the fossil record. So, I encouraged [Jung and co-authors Minguk Kim and Hyemin Jo] to visit Texas and the University of Texas High-Resolution X-ray Computed Tomography (UTCT) [facility], to try scanning the fossil.
Because the researchers found Doolysaurus largely encased in rock, they hope more dinosaur bones await discovery in South Korea. Jung also hopes to continue using micro-CT technology to expose more hidden fossils.
Bottom line: Scientists discovered a new dinosaur, thought to be two years old, and named it after Dooly, a popular South Korean baby dinosaur cartoon character.
