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.

Security Council to Hold Emergency Meeting on Middle East Crisis

UN Secretary-General António Guterres on Saturday condemned the “military escalation in the Middle East” following attacks by the United States and Israel against Iran and Tehran’s retaliatory strikes, just hours before an urgent meeting of the UN Security Council.

“I call for the immediate cessation of hostilities and de-escalation,” Guterres said in a statement.

The Security Council is scheduled to meet on Saturday at 21:00 GMT (4:00 p.m. in New York) to address “the situation in the Middle East,” the United Nations announced.

The meeting, during which Guterres will deliver remarks, was convened at the request of France, Bahrain, Colombia, Russia and China, according to a diplomatic source.

Trump Floats “Friendly Takeover” of Cuba Amid Rising Tensions

U.S. President Donald Trump said Friday that his administration is considering what he described as a “friendly takeover” of Cuba, as Washington continues to increase pressure on the island’s communist government.

“The Cuban government is talking to us and they have very serious problems, as you know. They have no money, they have nothing at this moment, but they are talking to us and maybe we will see a friendly takeover of Cuba,” Trump told reporters as he departed the White House for a trip to Texas.

Earlier in the week, U.S. Secretary of State Marco Rubio said Cuba needed a “radical change,” shortly after Washington eased restrictions on oil exports to the island for what officials described as “humanitarian reasons,” amid a deep economic crisis.

The United States has imposed an energy blockade on Cuba since January, citing what it calls an “extraordinary threat” posed by the communist-run island, located roughly 150 kilometers (90 miles) off the coast of Florida, to U.S. national security.

Argentina’s Senate Reviews Milei-Backed Labor Overhaul

Argentina’s Senate on Friday began reviewing the Labor Modernization Law promoted by the administration of President Javier Milei, a proposal that would significantly reshape labor rules across the country.

The upper chamber opened its final discussion of the contentious initiative, which revises the method used to calculate severance payments — lowering the amounts owed in dismissal cases — and introduces an “hour bank” mechanism that allows overtime to be offset with paid leave rather than extra wages.

The legislation also broadens the classification of essential services, a change that would place new limits on the right to strike in designated sectors.

The bill was initially approved by the Senate on February 11 and then moved to the Chamber of Deputies, where lawmakers passed it with amendments. It has now returned to the Senate for definitive approval.

Outside the Congress building in Buenos Aires, workers, trade unions and left-wing organizations staged demonstrations beginning at midday. The gathering later thinned out amid reports of disturbances and a strong police presence. Security forces had secured the area surrounding the legislature since early morning hours.

Union leaders contend that the reform weakens labor protections, while many business representatives back the measure but stress that sustainable formal employment will require economic expansion, improved credit conditions, greater investment and a more dynamic domestic market.
