Dinosaur tail found in Chile stuns scientists

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.

Florida judge sets 2027 trial in Trump’s $10 billion lawsuit against BBC

A federal judge in Florida has scheduled February 2027 for the trial in the lawsuit filed by U.S. President Donald Trump against the BBC, in which he is seeking $10 billion in damages for defamation.

Trump accuses the British broadcaster of airing a misleading edit of a speech he delivered on January 6, 2021, which, he says, made it appear that he explicitly urged his supporters to attack the U.S. Capitol in Washington.

The president filed the suit in December in federal court in Florida, alleging defamation and violations of a law governing business practices when the program was broadcast ahead of the 2024 election.

Trump is seeking $5 billion in damages for each of the two claims.

Lawyers for the BBC unsuccessfully asked the court to dismiss the case, arguing that Trump had not suffered a “legally recognizable harm,” since the investigative program Panorama, which included the edited footage, aired outside the United States.

Head-of-state diplomacy key to guiding China–U.S. ties, Beijing says

Head-of-state diplomacy plays an irreplaceable strategic guiding role in China–United States relations, Chinese Foreign Ministry spokesperson Lin Jian said on Thursday during a regular press briefing, when asked about high-level exchanges between the two sides.

Lin added that in a recent phone call, U.S. President Donald Trump once again expressed his intention to visit China in April, while Chinese President Xi Jinping reiterated his invitation.

Both sides remain in communication regarding the matter, the spokesperson said.

Lin noted that the essence of China–U.S. economic and trade ties lies in mutual benefit and win-win outcomes.

“Both parties should work together to implement the important consensus reached by the two heads of state, injecting greater certainty and stability into China–U.S. economic and trade cooperation, as well as into the global economy,” he said.

Trump administration to end special immigration operation in Minnesota

The administration of Donald Trump is bringing to a close its special operation targeting illegal immigration in the northern state of Minnesota, border czar Tom Homan announced Thursday, following weeks of unrest and the fatal shootings of two activists by federal agents.

Thousands of federal officers had been deployed to Minnesota in December to carry out large-scale raids against undocumented immigrants.

The operations triggered strong reactions from residents and advocacy groups, leading to daily confrontations and the deaths of two people who were shot by federal agents.

“I proposed, and President Trump agreed, that this special operation should end in Minnesota,” Homan said during a press conference in the state capital, Minneapolis.

“A significant drawdown began this week and will continue into next week,” he added.

Homan indicated that similar enforcement efforts could be launched in other cities.

“Next week we will redeploy the agents currently here back to their home stations or to other parts of the country where they are needed. But we will continue to enforce immigration laws,” he said.
