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.

German president says trust in U.S. leadership is ‘lost’ amid global tensions
German President Frank-Walter Steinmeier said on Tuesday that trust between the United States and its Western allies has been “lost,” warning that the damage could persist beyond the presidency of Donald Trump.
“The rupture is very deep, and the loss of trust in U.S. great power policy is significant—not only among its allies, but also, as I observe, globally,” Steinmeier said during a speech in Berlin marking the 75th anniversary of Germany’s Foreign Ministry.
Referring to the future of transatlantic relations, he stated that “there is no return to the situation before January 20, 2025,” the date marking the start of Trump’s second term in the White House.
“Even a future U.S. administration will no longer be able to resume the role of a benevolent hegemon guaranteeing a liberal international order,” added Steinmeier, who previously served as Germany’s foreign minister.
He also criticized the war against Iran, describing it as “contrary to international law” and calling it “a political mistake with serious consequences.”
“This war is avoidable and unnecessary,” he said.
Although the German presidency is largely ceremonial, Steinmeier’s remarks reflect a broader concern within Germany, aligning with the government’s cautious stance while going further in tone.

Trump claims talks with Iran as G7 meets to address global tensions
U.S. President Donald Trump said that the United States has held talks with Iran—a claim denied by Tehran—and has temporarily paused his threat to target the country’s electrical infrastructure.
In his first overseas trip since the United States and Israel launched their offensive on February 28, U.S. Secretary of State Marco Rubio is expected to address key global issues, including the situation in the Middle East, according to State Department spokesperson Tommy Pigott.
Foreign ministers from the Group of Seven will meet in Cernay-la-Ville, close to Versailles, on the outskirts of Paris.
During the meeting, Rubio will hold discussions with his counterparts on “the war between Russia and Ukraine, the situation in the Middle East, and threats to global peace and stability,” Pigott said.
France currently holds the presidency of the G7, whose members also include the United Kingdom, Canada, Germany, Italy, and Japan.
Although all G7 nations are close allies of the United States, none has offered explicit support for Washington’s military actions against Iran, a stance that has reportedly frustrated Trump.
Last Saturday, G7 foreign ministers called for an “immediate and unconditional end” to Iranian attacks against U.S. allies in the Middle East.

Pentagon to deploy 3,000 troops to Persian Gulf as Middle East tensions escalate
The Pentagon is planning to deploy nearly 3,000 troops from the 82nd Airborne Division to the Persian Gulf, according to two senior officials cited Tuesday by Spanish newspaper El País.
Meanwhile, Hezbollah warned it would confront any attempt at occupation following Israel’s announcement that its military will take control of southern Lebanon up to the Litani River, located about 30 kilometers from the border.
In recent hours, the Israel Defense Forces carried out airstrikes on Beirut, while Iran and Hezbollah responded with attacks on Israel, leaving at least six people with minor injuries in Tel Aviv.
The escalation comes as global markets react to renewed instability. The price of oil rose again above $100 per barrel after a brief decline the previous day, following an announcement by U.S. President Donald Trump of a five-day truce on attacks targeting Iran’s energy infrastructure.
Despite the announcement, Iranian authorities reported that two projectiles struck a gas pipeline in Khorramshahr and administrative buildings at a gas facility in Isfahan early Tuesday.
