NEW YORK: Not all two-legged dinosaurs were like the lumbering Tyrannosaurus rex.
An analysis of dinosaur tracks from 120 million years ago unearthed in Spain adds to growing evidence that these meat-eating prehistoric beasts belonging to the same group as T.rex could be highly agile.
The findings, published Thursday in Scientific Reports, reveal one of the fastest known sets of fossilized dinosaur footprints.
These tracks join the ranks of other speedy sets found in Utah and Texas, one of which shows dinosaurs running at speeds over 30 mph. The Spanish footprints showed speeds of nearly 28 mph.
To calculate the running speed, scientists measured the length of the footprint and took into account the dinosaur’s hip height and stride length — the distance between two consecutive footprints of the same foot.
All of the fastest known sets of prints come from a family of dinosaurs called theropods. These carnivorous dinosaurs stood on two legs and could not fly, like the famed velociraptor. The animals that created the most recent impressions were probably 5 to 6 1/2 feet tall and 13 to 16 feet long from mouth to tail, the researchers estimated.
Scientists think there may be other faster dinosaurs, but the tracks of theropods have been easier to track down.
“Behavior is something very difficult to study in dinosaurs,” said lead author Pablo Navarro-Lorbés of the University of La Rioja. “These kind of findings are very important, I think, for improving that kind of knowledge.”
Scientists typically predict dinosaur behavior through computer modeling of the creatures’ movement. Physical examination of fossilized footprints confirm the results.
These are “clearly active, agile animals,” said Smithsonian paleontologist Hans Sues, who had no role in the study.

Cambodia takes back looted historic artifacts handled by British art dealer
- The objects were returned under a 2020 agreement between the Ministry of Culture and Fine Arts and the family of the late Douglas Latchford, a British art collector and dealer who allegedly had the items smuggled out of Cambodia
PHNOM PENH, Cambodia: Cambodian officials on Friday received more than six dozen historic artifacts described as part of the country’s cultural heritage that had been looted during decades of war and instability.
At a ceremony attended by Deputy Prime Minister Hun Many, the 74 items were unveiled at the National Museum in Phnom Penh after their repatriation from the United Kingdom.
The objects were returned under a 2020 agreement between the Ministry of Culture and Fine Arts and the family of the late Douglas Latchford, a British art collector and dealer who allegedly had the items smuggled out of Cambodia.
“This substantial restitution represents one of the most important returns of Khmer cultural heritage in recent years, following major repatriations in 2021 and 2023 from the same collection,” the Culture Ministry said in a statement. “It marks a significant step forward in Cambodia’s continued efforts to recover, preserve, and restore its ancestral legacy for future generations.”
The artifacts were described as dating from the pre-Angkorian period through the height of the Angkor Empire, including “monumental sandstone sculptures, refined bronze works, and significant ritual objects.” The Angkor Empire, which extended from the ninth to the 15th century, is best known for the Angkor Wat archaeological site, the nation’s biggest tourist attraction.
Latchford was a prominent antiquities dealer who allegedly orchestrated an operation to sell looted Cambodian sculptures on the international market.
From 1970 to the 1980s, during Cambodia’s civil wars and the communist Khmer Rouge ‘s brutal reign, organized looting networks sent artifacts to Latchford, who then sold them to Western collectors, dealers, and institutions. These pieces were often physically damaged, having been pried off temple walls or other structures by the looters.
Latchford was indicted in a New York federal court in 2019 on charges including wire fraud and conspiracy. He died in 2020, aged 88, before he could be extradited to face charges.
Cambodia, like neighboring Thailand, has benefited from a trend in recent decades involving the repatriation of art and archaeological treasures. These include ancient Asian artworks as well as pieces lost or stolen during turmoil in places such as Syria, Iraq and Nazi-occupied Europe. New York’s Metropolitan Museum of Art is one of the prominent institutions that has been returning illegally smuggled art, including to Cambodia.
“The ancient artifacts created and preserved by our ancestors are now being returned to Cambodia, bringing warmth and joy, following the country’s return to peace,” said Hun Many, who is the younger brother of Prime Minister Hun Manet.
