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.

Mexico City Mayor Invites U2 to Perform at Iconic Zócalo Plaza
Irish rock band U2, which spent Tuesday and Wednesday filming a new music video for its song Street of Dreams in the Historic Center of Mexico City, received an invitation to perform at the capital’s iconic Zócalo square from Mayor Clara Brugada.
Brugada shared the invitation through social media posts accompanied by photos and a video showing her meeting with the band members.
“This is an invitation for you to perform in our wonderful public square, the Zócalo. You are welcome here, and we would love to have you,” Brugada said in the video while handing a document to Bono, the band’s lead singer.
Bono responded by saying that the group would like “to begin its new tour in Mexico City.”
Referencing one of the band’s most famous songs, In the Name of Love, Brugada said she was greeting Bono along with The Edge, Adam Clayton and Larry Mullen Jr..
“Welcoming U2 to our capital means celebrating music, connection and the emotion that can be felt in every corner of this city,” Brugada wrote in one of her messages. “We are a city open to the world, vibrant and full of stories shared from the stage to the streets.”
She also described the Zócalo as “the country’s most important public square” and a cultural landmark for Latin America.
Over the years, the Zócalo has hosted massive concerts by internationally renowned artists and bands including Roger Waters, Paul McCartney, Manu Chao, Café Tacvba, Los Fabulosos Cadillacs, Los Tigres del Norte, La Maldita Vecindad, Silvio Rodríguez, Joan Manuel Serrat, Rosalía and Shakira, drawing hundreds of thousands of fans.

Marco Rubio Urges China to Help Restrain Iran Amid Gulf Tensions
Marco Rubio said Wednesday that Washington hopes to persuade China to take a more active role in stopping Iran from escalating tensions in the Persian Gulf, arguing that the crisis directly threatens Asian commercial interests.
“It is in China’s interest to resolve this situation. We hope to convince them to play a more active role in getting Iran to stop what it is doing now and trying to do in the Persian Gulf,” Rubio said during an interview with journalist Sean Hannity on Fox News while traveling aboard Air Force One.
The top U.S. diplomat said the conflict and concerns over the possible disruption of the Strait of Hormuz have already affected China’s interests.
Rubio noted that “a Chinese cargo ship was struck over the weekend,” referring to the exchange of attacks reported last Friday between Iran and the United States.
The remarks come amid growing international concern over rising tensions in the region and the potential impact on global trade routes and energy supplies.

Trump floats Vance-Rubio potential Republican ticket for 2028 election
U.S. President Donald Trump suggested on Monday that Vice President JD Vance and Secretary of State Marco Rubiocould potentially form a Republican presidential ticket for the 2028 elections.
Speaking during a dinner with law enforcement officials as part of National Police Week, Trump publicly praised both officials and said they could make “an ideal team” for the next presidential race.
“Who likes JD Vance? Who likes Marco Rubio?” Trump asked attendees before adding that the pair “sound like a good combination.”
The president highlighted his vice president’s performance in office, stating that their current partnership has been highly effective. “JD is perfect, that has been a perfect formula,” Trump told reporters later.
He further suggested that a Vance-Rubio pairing could represent a strong presidential and vice-presidential ticket, although he stopped short of offering any formal endorsement.
“I think it sounds like a presidential candidate and a vice-presidential candidate,” he said, while clarifying that his remarks should not be interpreted as an official backing of any future campaign.
So far, neither Vance nor Rubio has publicly confirmed any intention to run in the 2028 presidential election.
Rubio previously sought the Republican nomination in 2016 but withdrew after losing the primary race to Trump. Later, in a December 2025 interview with Vanity Fair, he said he would be among the first to support Vance if he decided to run for the White House.
Vance, meanwhile, has recently dismissed speculation of any political rivalry with Rubio amid growing discussion about potential future GOP leadership.
