Dinosaur tail found in Chile stuns scientists

AFP

Chilean paleontologists on Wednesday presented their findings on a dinosaur discovered three years ago in Patagonia which they said had a highly unusual tail that has stumped researchers

The remains of the Stegouros elengassen were discovered during excavations in 2018 at Cerro Guido, a site known to harbor numerous fossils, by a team who believed they were dealing with an already known species of dinosaur until they examined its tail.

“That was the main surprise,” said Alexander Vargas, one of the paleontologists. “This structure is absolutely amazing.”

“The tail was covered with seven pairs of osteoderms … producing a weapon absolutely different from anything we know in any dinosaur,” added the researcher during a presentation of the discovery at the University of Chile.

The osteoderms — structures of bony plaques located in the dermal layers of the skin – were aligned on either side of the tail, making it resemble a large fern.

Paleontologists have discovered 80 percent of the dinosaur’s skeleton and estimate that the animal lived in the area 71 to 74.9 million years ago. It was about two meters (almost seven feet) long, weighed 150 kilograms (330 pounds) and was a herbivore.

According to the scientists, who published their research in the journal Nature, the animal could represent a hitherto unknown lineage of armored dinosaur never seen in the southern hemisphere but already identified in the northern part of the continent.

“We don’t know why (the tail) evolved. We do know that within armored dinosaur groups there seems to be a tendency to independently develop different osteoderm-based defense mechanisms,” said Sergio Soto, another member of the team.

The Cerro Guido area, in the Las Chinas valley 3,000 km (1,800 miles) south of Santiago, stretches for 15 kilometers. Various rock outcrops contain numerous fossils.

The finds there allowed the scientists to surmise that present-day America and Antarctica were close to each other millions of years ago.

“There is strong evidence that there is a biogeographic link with other parts of the planet, in this case Antarctica and Australia, because we have two armored dinosaurs there closely related” to the Stegouros, said Soto.

Report: Vatican mediation included russian asylum offer ahead of Maduro’s capture

The Vatican reportedly attempted to negotiate an offer of asylum in Russia for Venezuelan President Nicolás Maduro before his capture by U.S. forces last Saturday, according to The Washington Post.

The U.S. newspaper reported that Vatican Secretary of State Cardinal Pietro Parolin spoke with U.S. Ambassador to the Holy See Brian Burch about a supposed Russian proposal to grant Maduro asylum. A source familiar with the offer said that what was proposed “was that he would leave and be able to enjoy his money,” and that part of the plan involved Russian President Vladimir Putin guaranteeing Maduro’s security.

Despite these diplomatic efforts, the United States carried out a military operation that resulted in Maduro’s capture and detention, along with his wife Cilia Flores, who are now being held in New York on narcoterrorism charges.

The Washington Post also noted that U.S. President Donald Trump may have invited Maduro to Washington for in-person discussions about safe conduct, an offer that Maduro reportedly declined.

Pope Leo XIV warns of rising “war enthusiasm” in global politics

“War is becoming fashionable again, and war enthusiasm is spreading.” Pope Leo XIV delivered a somber assessment of international politics on Friday, sharply criticizing the growing reliance on force by nations at a time when his country of birth is increasing military displays.

While offering New Year’s greetings to the diplomatic corps, the U.S.-born pope — who also holds Peruvian nationality — delivered one of his strongest speeches to date, denouncing the “worrying weakening of multilateralism” and the emergence of what he described as “war enthusiasm.”

From the outset of his address to ambassadors accredited to the Holy See, delivered in English, the pontiff lamented the rise of a “diplomacy of force, by individuals or groups of allied states,” at the expense of dialogue, warning that such trends threaten the global order established after World War II.

“Peace is no longer sought as a gift or as a good desirable in itself, or as the pursuit of ‘the establishment of an order willed by God, one that entails greater justice among human beings.’ Instead, it is pursued through weapons as a condition for asserting one’s own dominance,” the head of the Catholic Church said, without directly naming any country.

His remarks come amid ongoing conflicts between Ukraine and Russia and in the Gaza Strip, and against a broader international backdrop marked by European concerns over a potential U.S. takeover of Greenland, the autonomous Danish territory, a scenario that could threaten the cohesion of NATO.

The incident occurred at around 4:10 p.m. local time in the Carabanchel neighborhood, in the southwest of the Spanish capital, according to a spokesperson for emergency services.

One person, whose identity was not disclosed, was killed, and nine others sustained minor injuries, the spokesperson said.

When asked about the possible cause of the explosion, emergency services did not provide any details.

Images shared by authorities on their official X account show a partial collapse of the building’s façade.

In October 2025, the collapse of a building under renovation in central Madrid left four people dead.
