Tyrannosaurus Rex relative discovered: New dinosaur species identified in Mongolia

A new dinosaur species, related to the famous Tyrannosaurus rex, has been discovered by paleontologists. The fossils, originally found in the 1970s, were recently reanalyzed after Jared Voris, a Ph.D student in the University of Calgary's Department of Earth Energy and Environment, noticed the dinosaur remains during a trip to Mongolia in 2023. The new species has been named Khankhuuluu mongoliensis, meaning 'Prince of Dragons of Mongolia."
The fossils consisted of two partial skeletons found in Mongolia's Gobi Desert in the 1970s. A Mongolian paleontologist had initially attributed the remains as those of the meat-eating dinosaur Alectrosaurus olseni, Darla Zelenitsky, an associate professor at the University of Calgary's Faculty of Science, told ABC News. The fossils had not been "seriously" looked at since then, she noted. She was part of a group that authored a study related the new discovery in the journal Nature.
According to ABC News, Jared Voris noticed the fossils in a glass case while on a visit to the Central Museum of Dinosaurs of Mongolia. He realized that the remains had characteristics that were never seen before in a Tyrannosaurus species. The skull contained an air cavity close to the nose. The toe bones were attached to the leg of a predator in a different manner.
The results of the study mean that the fossils help fill a gap between the early ancestors of Tyrannosaurus rex and the predators that evolved later. 'They're almost the immediate ancestor of the family that we call tyrannosaurs,' Dr Darla Zelenitsky told the Guardian.
The dinosaurs were believed to weigh around 750 kilos. The creature was about four meters in length. According to Voris, if humans had lived at the same time as the dinosaur, they would have been a perfect meal for the Khankhuuluu. As per researchers, the species was related to the Eutyrannosaurias, which originated in North America and included T-rex.
The discovery sheds light on Alioramus, a group of small, long-nosed tyrannosaurs also called 'Pinocchio rexes.' Some experts had proposed that the species might sit closer to the ancestors of tyrannosaurs than believed earlier. However, the discovery of the Khankhuuluu has shown this was not the case.
The T-Rex was among the biggest predators in North America until 66 million years ago, when an asteroid slammed into the Gulf of Mexico, wiping out three-quarters of all life on Earth.
It is a new dinosaur species related to the Tyrannosaurus rex. Its name means 'Prince of Dragons of Mongolia'.
The dinosaur was an apex predator. Its size, speed and portrayal in films has made it among the most famous dinosaurs of all time.
The fossils of the Khankhuuluu mongoliensis were found in Mongolia in the 1970s.

Meet the 'Dragon Prince': New dinosaur discovery rewrites the Tyrannosaur family tree

A fascinating fossil discovery in Mongolia has uncovered a new species of dinosaur that could reshape everything we thought we knew about the evolution of Tyrannosaurs. Named Khankhuuluu Mongoliensis, or "Dragon Prince of Mongolia", this 86-million-year-old predator is now considered the closest known ancestor of the fearsome Tyrannosaurus rex. With its transitional traits and smaller size, the find reveals a crucial evolutionary chapter between small, agile hunters and the massive apex predators that ruled the Late Cretaceous. Scientists say the discovery, buried for decades in a museum collection, offers fresh insight into how Tyrannosaurs evolved their powerful bite, skull shape, and dominant ecological role in both Asia and North America. A dinosaur fossil of 'Dragon Price' hidden in plain sight The partial skeletons that led to this discovery were actually excavated in Mongolia back in the 1970s. At the time, they were thought to belong to a species called Alectrosaurus. It wasn't until PhD student Jared Voris took a closer look, decades later, that the unique features of this new species began to emerge. Working alongside Professor Darla Zelenitsky from the University of Calgary, Voris spotted key differences in the skull and nasal bones that clearly separated it from other known dinosaurs. What is Khankhuuluu Mongoliensis Named after the word for 'dragon' in Mongolian and the region it was found in, Khankhuuluu Mongoliensis bridges a crucial gap in the Tyrannosaur timeline. Weighing around 750 kilograms, it was far smaller than the T. rex, which could tip the scales at over 6 tonnes. But it had key traits that hint at the future kings of the dinosaur world. Its skull showed signs of strengthening, and its jaw was developing the structure needed for the bone-crushing bite Tyrannosaurs are known for. The evolution of Tyrannosaurs Early members of the Tyrannosaur family were small, quick-footed hunters living in the shadows of larger meat-eaters. Khankhuuluu represents a shift from these agile predators towards the bulkier, more powerful giants of the Late Cretaceous. With stronger jaws and a larger build than its predecessors, it shows how evolution favoured size and strength over time. These adaptations eventually led to the dominance of species like T. rex, which could take down massive prey and even crush bones. A journey across continents Another important insight from this discovery is the role of ancient land bridges between Asia and North America. During the Late Cretaceous period, areas like Siberia and Alaska were connected, allowing species like Tyrannosaurs to migrate and evolve in new environments. This movement helped spark the emergence of distinct groups on different continents, explaining how similar predators could be found in both Asia and North America. Rewriting the family tree With the addition of Khankhuuluu Mongoliensis to the record, palaeontologists now have a clearer picture of how Tyrannosaurs evolved. It fills a key gap between the small early forms and the gigantic predators that came later. The findings, published in the journal Nature, could prompt scientists to revisit other old fossils that may have been misclassified. This discovery serves as a reminder that sometimes the answers to big questions have been waiting quietly in storage. What museum collections can still teach us What makes this story even more remarkable is that the fossil had been sitting in a Mongolian museum for over 40 years. It highlights how valuable museum collections are and how new techniques, fresh perspectives and even young researchers can uncover major breakthroughs from existing specimens. Not every discovery requires a dig, some are hidden in plain sight. Before the kings, there were princes The discovery of Khankhuuluu Mongoliensis gives us a rare look at the early days of a dynasty. While this dinosaur didn't have the size or fearsome presence of its famous descendants, it carried the building blocks of what would become one of Earth's most iconic predators. As Professor Zelenitsky put it, 'Before Tyrannosaurs became the kings, they were princes.' And this dragon prince may just be the missing link we didn't know we needed.

Harvard scientist accused of smuggling frog embryos, ‘biological materials' to US; trial begins

In a US court hearing on Wednesday, attorneys argued over whether a Harvard researcher accused of smuggling frog embryos brought 'biological materials' in the US. Russian-born scientist named Kseniia Petrova, aged 30, conducting cancer research for Harvard Medical School, appeared in Massachusetts federal court, ABC News reported. In February, Petrova was questioned by US Customs and Border Protection at Boston Logan International Airport, while she was returning from a vacation in France. Earlier, she had stopped at a lab specialising in splicing superfine sections of frog embryos and obtained a package of samples for research. Federal officials accused her of lying about 'carrying substances' into the country and alleged that Petrova planned to smuggle the embryos through customs without declaring them. Meanwhile, Petrova told Associated Press news agency in an interview that she did not know the items needed to be declared and was not trying to sneak anything into the country. She also said that her visa was being canceled and detained by immigration officials in Vermont after her initial arrest. After filing a petition for her release, she was briefly sent to an ICE facility in Louisiana, after which a judge ruled the immigration officers' actions were unlawful. In May, she was charged with one count of smuggling. The Homeland Security Investigations agent, Brian Goldsworthy, who wrote the affidavit in support of the criminal complaint against Petrova, testified that Petrova would not have been allowed to leave the airport had she declared the frog embryos in her luggage, ABC News reported. He also said that Customs and Border Protection agriculture experts and a federal laboratory that reviewed the samples deemed them to be biological material, ABC News reported. In Petrova's defense, her attorney argued that it was unclear what definition of biological material, government was operating under. After the hearing, both sides will now have the chance to submit briefs to the judge. If convicted of the charges, Petrova could face up to 20 years in prison and a fine of up to $250,000.

Australian Researchers Develop AI Model That Turns Brainwaves Into Words

Australian scientists are developing an artificial intelligence (AI) system that decodes brainwaves into text, or simply put, thoughts from brainwaves. While doctors use electroencephalogram (EEG) to diagnose brain conditions, researchers at Sydney's University of Technology (UTS) are using it to read thoughts. An AI Model, developed by PhD students Charles (Jinzhao) Zhou and his supervisors Chin-Teng Lin and Dr Leong, uses deep learning to translate the brain signals from EEG into specific words. "I am jumping happily, it's just me," the AI model produced the result when Dr Leong wore the 128-electrode EEG cap and did not utter a single word. Currently, the AI model has been trained on a small set of words and sentences to simplify the process of recognising each word, according to a report in ABC News. The AI is used to filter out noise and clarify the brain signals because signals from different brain sources overlap on the skull's surface, he added. While Elon Musk's Neuralink is known for producing something similar, the research by the Sydney scientists is non-invasive in nature. "We can't get very precise because with non-invasive, you can't actually put it into that part of the brain that decodes words," said Mr Lin. The technology has immense implications for stroke rehabilitation, speech therapy in autism, and restoring communication for paralysis patients. AI and human brain Across the globe, scientists have been combining EEG and AI to produce impressive results. In April, researchers at Mass General Brigham came up with an AI tool capable of predicting brain decline in patients, years in advance. The AI tool analyses subtle changes in brain activity during sleep using EEG to make the prediction. During one of the studies, it correctly flagged 85 per cent of individuals who eventually experienced cognitive decline, with an overall accuracy of 77 per cent.
