Tiny tyrannosaur species discovered in Mongolia
A new species of dinosaur has been discovered, which scientists say shows how tyrannosaurs evolved from smaller predators the size of a horse. The 'Dragon Prince', whose bones were found in a Mongolian museum, is thought to be about 20 million years older than the Tyrannosaurus Rex and provides a 'missing link' in the evolution of the apex predators. The skeleton of the Khankhuuluu Mongoliensis demonstrates where the T-Rex got its vicious bite, researchers who 'rediscovered' the species said. 'We see features in its nasal bone that eventually gave tyrannosaurs those very powerful bite forces,' said Jared Voris, from the University of Calgary, the researcher who found the bones. The fossils were initially found in the early 1970s, but at the time were misidentified as belonging to a different tyrannosaur, Alectrosaurus. The bones were put away in a drawer at the Institute of Palaeontology of the Mongolian Academy of Sciences in the capital Ulaanbaatar, until they were re-discovered by then-PhD student Mr Voris. He was handed two plastic tubes full of bones while visiting the institute – and eventually found the fossils were partial skeletons of two different dinosaurs from a new species. Darla Zelenitsky, a palaeontologist from the University of Calgary, said: 'It is quite possible that discoveries like this are sitting in other museums that just have not been recognised.' The skeleton shows that the 'Dragon Prince' was about four metres long and weighed only 750kg, according to the findings, published in the academic journal Nature. An adult T-Rex is believed to have weighed eight times as much. 'They were these really small, fleet-footed predators that lived in the shadows of other apex predatory dinosaurs,' said Dr Voris. 'This discovery shows us that, before tyrannosaurs became the kings, they were princes,' said Zelenitsky. The finding is considered a 'transitional' fossil and has helped clarify the evolution of the tyrannosaur family, which was 'really messy previously,' said Dr Zelenitsky. 'What makes them so important is their age,' said Stephen Brusatte, a palaeontologist at the University of Edinburgh who was not involved in the study. 'They are about 86 million years old, a good 20 million years older than T-Rex. It has been a frustrating gap in the record.' The discovery also helps to paint the migration patterns of the tyrannosaurs. They show that T-Rex's direct ancestors probably migrated from Asia to North America across a land bridge that used to connect Siberia and Alaska 85 million years ago, Dr Zelenitsky said. Tyrannosaurs then evolved in North America and remained there for the next several million years, she said. 'As the many tyrannosaur species evolved on the continent, they became larger and larger,' said Dr Zelenitsky. The records are incomplete so scientists are unsure of what happened in Asia 80 million years ago. However, the Khankhuuluu may have later been replaced by larger, more dominant, tyrannosaurs.

New dinosaur species, the 'Dragon Prince', discovered — what did it look like?
Representational image Hold onto your fossil hats, dinosaur lovers—there's a new prehistoric rockstar in town, and it goes by a name that sounds like it just flew out of a fantasy novel. Say hello to Khankhuuluu mongoliensis, nicknamed the 'Dragon Prince. ' And yes, it's just as cool as it sounds. The findings have been published in Nature . So, what exactly is Khankhuuluu? This ancient predator stomped around what's now Mongolia about 86 million years ago, way before the iconic Tyrannosaurus rex came on the scene. Khankhuuluu was no tiny lizard—but it definitely wasn't the hulking beast T. rex turned out to be. Think of it as the lean, speedy older cousin that paved the way for future dinosaur royalty. It weighed 750 kilos. The wild part? Scientists actually found Khankhuuluu's fossils back in the 1970s, but they thought it was part of a different species. Fast forward a few decades and some super high-tech scans later, and—boom!—turns out we've had a brand-new species hiding in plain sight this whole time. Talk about a plot twist in the fossil record. What did it look like? Unlike the bulky, bone-crushing T. rex, Khankhuuluu was all about agility. It had a slim build, long legs made for sprinting, and a narrow snout packed with sharp teeth—perfect for snapping up smaller prey like oviraptorosaurs and ornithomimosaurs. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Men Over 50: Frequent Urination & Weak Stream?

"'Prince' refers to this being an early, smaller tyrannosauroid," explained Prof Darla Zelenitsky, a palaeontologist from the University of Calgary in Canada told BBC. Tyrannosauroids are the superfamily of carnivorous dinosaurs that walked on two legs. "They were these really small, fleet-footed predators that lived in the shadows of other apex predatory dinosaurs," PhD student Jared Voris, who led the research with Prof Zelenitsky, told the media. They added that Khankhuuluu probably weighed around 750 kilos (about 1,650 pounds). Not bad for an early tyrannosaur, right? A dino with a passport? Besides being a missing puzzle piece in the tyrannosaur family tree, Khankhuuluu is also helping scientists figure out where these dinos came from and how they moved around. The new theory? Tyrannosaurs may have started in Asia, made their way to North America, and then boomeranged back to Asia. This epic dino road trip might explain the range of species we've dug up across continents. Why this matters The discovery of the 'Dragon Prince' is more than just another cool name—it's a reminder that our planet's past is full of surprises waiting to be uncovered. Every fossil, every re-examined bone, tells a deeper story about where life came from and how it evolved. So next time someone mentions the mighty T. rex, throw a little respect to its slimmer, faster, older cousin—Khankhuuluu mongoliensis, the prehistoric royalty that sprinted so the king could roar.

New Tyrannosaur species reshapes T. rex family tree
A newly identified dinosaur species from Mongolia is rewriting the history of the T. rex family tree. Dubbed the 'Dragon Prince' (scientifically named Khankhuuluu mongoliensis), this prehistoric predator lived about 86 million years ago and is believed to be a key ancestor of the famous Tyrannosaurus rex. For decades, fossils of this dinosaur sat largely overlooked in museum collections, misidentified as a known species called Alectrosaurus. But recent re-examination by researchers revealed that the fossils represent a completely new species — one that provides a vital missing link between smaller early tyrannosaurs and the massive apex predators that later dominated Earth. At about 13 feet long and weighing about 1,650 pounds, the Dragon Prince was much smaller than later tyrannosaurs like T. rex, which could grow up to 41 feet long and weigh more than 23,000 pounds. It had a smaller head and longer arms compared to its gigantic descendants, meaning it may have occupied an in-between evolutionary phase. Scientists say the discovery fills a crucial gap in understanding how tyrannosaurs evolved from modest-sized hunters to colossal rulers of their ecosystems. Paleontologists believe the Dragon Prince primarily hunted prey smaller than itself, unlike later giants that tackled enormous herbivores. Beyond its size and anatomy, experts say the find offers fresh insights into tyrannosaur migration patterns. Research shows that around 85 million years ago, a species closely related to K. mongoliensis migrated from Asia to North America across a land bridge near today's Bering Strait. This migration likely gave rise to the first true tyrannosaurs in North America, which went on to become dominant predators of the Late Cretaceous period. Later migrations back and forth between Asia and North America helped shape tyrannosaur diversity, producing both massive species like Tarbosaurus bataar and smaller, slimmer ones like Qianzhousaurus sinensis, nicknamed 'Pinocchio rex.' About 68 million years ago, one giant tyrannosaur species likely migrated back to North America and evolved into T. rex. This discovery, published in Nature, highlights how migration events fueled tyrannosaur evolution and offers a fascinating glimpse into the complex family tree of these iconic dinosaurs — the princes before they became kings.

Mongolia's 'Dragon Prince' dinosaur was forerunner of T. rex
This handout artist's illustration made available by University of Calgary on June 6, 2025, shows the newly discovered dinosaur species Khankhuuluu mongoliensis, an ancestor of Tyrannosaurus Rex. - AFP WASHINGTON: A newly identified mid-sized dinosaur from Mongolia dubbed the "Dragon Prince" has been identified as a pivotal forerunner of Tyrannosaurus rex in an illuminating discovery that has helped clarify the famous predator's complicated family history. Named Khankhuuluu mongoliensis, it lived roughly 86 million years ago during the Cretaceous Period and was an immediate precursor to the dinosaur lineage called tyrannosaurs, which included some of the largest meat-eating land animals in Earth's history, among them T. rex. Khankhuuluu predated Tyrannosaurus by about 20 million years. It was about 4 metres long, weighed about 750 kg, walked on two legs and had a lengthy snout with a mouthful of sharp teeth. More lightly built than T. rex, its body proportions indicate Khankhuuluu was fleet-footed, likely chasing down smaller prey such as bird-like dinosaurs called oviraptorosaurs and ornithomimosaurs. The largest-known T. rex specimen is 12.3 metres. Khankhuuluu means "Dragon Prince" in the Mongolian language. Tyrannosaurus rex means "tyrant king of the lizards." "In the name, we wanted to capture that Khankhuuluu was a small, early form that had not evolved into a king. It was still a prince," said paleontologist Darla Zelenitsky of the University of Calgary in Canada, co-author of the study published on Wednesday in the journal Nature. Tyrannosaurs and all other meat-eating dinosaurs are part of a group called theropods. Tyrannosaurs appeared late in the age of dinosaurs, roaming Asia and North America. Khankhuuluu shared many anatomical traits with tyrannosaurs but lacked certain defining characteristics, showing it was a predecessor and not a true member of the lineage. "Khankhuuluu was almost a tyrannosaur, but not quite. For example, the bone along the top of the snout and the bones around the eye are somewhat different from what we see in tyrannosaurs. The snout bone was hollow and the bones around the eye didn't have all the horns and bumps seen in tyrannosaurs," Zelenitsky said. "Khankhuuluu had teeth like steak knives, with serrations along both the front and back edges. Large tyrannosaurs had conical teeth and massive jaws that allowed them to bite with extreme force then hold in order to subdue very large prey. Khankhuuluu's more slender teeth and jaws show this animal took slashing bites to take down smaller prey," Zelenitsky added. The researchers figured out its anatomy based on fossils of two Khankhuuluu individuals dug up in the 1970s but only now fully studied. These included parts of its skull, arms, legs, tail and back bones. The Khankhuuluu remains, more complete than fossils of other known tyrannosaur forerunners, helped the researchers untangle this lineage's evolutionary history. They concluded that Khankhuuluu was the link between smaller forerunners of tyrannosaurs and later true tyrannosaurs, a transitional animal that reveals how these meat-eaters evolved from speedy and modestly sized species into giant apex predators. "What started as the discovery of a new species ended up with us rewriting the family history of tyrannosaurs," said University of Calgary doctoral student and study lead author Jared Voris. "Before this, there was a lot of confusion about who was related to who when it came to tyrannosaur species." Some scientists had hypothesized that smaller tyrannosaurs like China's Qianzhousaurus - dubbed "Pinnochio-rexes" because of their characteristic long snouts - reflected the lineage's ancestral form. That notion was contradicted by the fact that tyrannosaur forerunner Khankhuuluu differed from them in important ways. "The tyrannosaur family didn't follow a straightforward path where they evolved from small size in early species to larger and larger sizes in later species," Zelenitsky said. Voris noted that Khankhuuluu demonstrates that the ancestors to the tyrannosaurs lived in Asia. "Around 85 million years ago, these tyrannosaur ancestors crossed a land bridge connecting Siberia and Alaska and evolved in North America into the apex predatory tyrannosaurs," Voris said. One line of North American tyrannosaurs later trekked back to Asia and split into two branches - the "Pinnochio-rexes" and massive forms like Tarbosaurus, the researchers said. These apex predators then spread back to North America, they said, paving the way for the appearance of T. rex. Tyrannosaurus ruled western North America at the end of the age of dinosaurs when an asteroid struck Earth 66 million years ago. "Khankhuuluu was where it all started but it was still only a distant ancestor of T. rex, at nearly 20 million years older," Zelenitsky said. "Over a dozen tyrannosaur species evolved in the time between them. It was a great-great-great uncle, sort of." - Reuters

‘The missing link': Calgary researchers discover new early tyrannosaur species
Scientists from the University of Calgary have discovered a new dinosaur specimen that they say appears to be the 'missing link' in the evolution of tyrannosaurs. The specimen was originally discovered in Mongolia's Gobi Desert over 50 years ago in the 1970s. But its significance wasn't recognized until Darla Zelenitsky, an associate professor in the university's faculty of science, sent graduate student Jared Voris to Mongolia on a research trip. 'He was there a couple of years ago on this research trip and looked at the fossil and texted me (that) he thought it was a new species. I was like, 'yay,'' Zelenitsky told The Canadian Press. 'I said, 'This is good, but we don't want to jump the gun on this.' It turned out it (was) a new species.' The species, Khankhuuluu mongoliensis — meaning 'Dragon Prince' or 'Prince of Dragons of Mongolia' — is believed to have crossed via a land bridge from Siberia to Alaska roughly 85 million years ago. Story continues below advertisement Zelenitsky said it appears to sit on the evolutionary scale between smaller tyrannosauroids and tyrannosaurs. 'It's the missing link between smaller tyrannosauroids and the large predatory tyrannosaurs,' she said.

Its ancestors were a couple of hundred kilograms and just tiny, but then when you get to tyrannosaurs proper, they were over a thousand kilograms, up to estimates of 5,000 kilograms.' The findings were published Wednesday in the British weekly scientific journal Nature. 'It's really exciting to be involved in a discovery of something that's been sitting in a drawer for 50 years. But it's even more exciting when it's a PhD student that makes that discovery,' Zelenitsky added. 'This discovery forced us to look at the family tree of tyrannosaurs in a very different light. It ended up with us rewriting the family history of tyrannosaurs.' Story continues below advertisement The arrival of Khankhuuluu or a similar species after moving from Asia to North America may have been the result of following their prey to a new location, said Zelenitsky. 'It's possible that there weren't many tyrannosaur type predators so it's possible they were able to take over that niche in North America and moved to the top of the food chain,' she said. 'Tyrannosaurs were in the right place at the right time. It allowed them to diversity and evolve a large body size, ultimately becoming the massive apex predator that terrorized North America and Asia during the late Cretaceous period.' Zelenitsky said the evolution to the tyrannosaur happened rapidly, geologically speaking, and probably took a few million years. She has co-authored over 50 different publications during her career and was part of a team that first found evidence of feathered dinosaurs in North America.
