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.

Iran issues threat to Trump as conflict escalates over Strait of Hormuz
The head of Iran’s Supreme National Security Council, Ali Larijani, threatened U.S. President Donald Trump on Tuesday, warning him to “beware of being eliminated.”
The Republican president had warned on Monday that he would strike Iran “very hard” if the Islamic Republic blocked oil shipments through the Strait of Hormuz, which has effectively been closed since the war began eleven days ago.
“Iran is not afraid of your empty threats. Others more powerful than you tried to destroy the Iranian nation and failed. Beware that you are not eliminated,” Larijani wrote on X.
Earlier, Iran’s Revolutionary Guards — the ideological military force of the Islamic Republic — also said their forces would move to block oil exports from the Gulf.
Meanwhile, Israeli Prime Minister Benjamin Netanyahu said Israel’s military offensive against Iran is far from over.
“Our aspiration is that the Iranian people free themselves from the yoke of tyranny; ultimately, that depends on them. But there is no doubt that with the measures taken so far we are breaking their bones, and we are not finished yet,” Netanyahu said in a statement.

Driver detained after suspicious vehicle incident near the White House
The driver was detained and no injuries were reported after an incident that occurred before dawn in Lafayette Square, just north of the White House.
The U.S. Secret Service, which is responsible for presidential security, said in a statement that it was “investigating a suspicious vehicle.” The driver of the car was taken into custody and is currently being questioned.
Washington remains under heightened security measures amid the ongoing conflict involving the United States and Israel against Iran.
Police closed several major streets around the White House. However, by about 8:30 a.m. local time (12:30 GMT), government employees and staff from nearby institutions were allowed to pass through the area with proper identification, according to an AFP journalist at the scene.
Dozens of emergency vehicles with flashing lights responded to the location, while tourists and residents waited for authorities to reopen the streets.

Trump Raises Possibility of “Friendly Takeover” of Cuba Amid Deepening Crisis
The President of the United States, Donald Trump, reiterated Monday the possibility that Washington could pursue a “friendly takeover” of Cuba, amid the severe crisis facing the island following the oil blockade promoted by the U.S. government.
Speaking at a press conference in Miami, the president said that U.S. Secretary of State Marco Rubio is currently “negotiating” with representatives of the Cuban government, although authorities in Havana have repeatedly denied that such talks are taking place.
Trump suggested that Washington could play a more direct role in the island’s future.
“It may be a friendly takeover. It may not be a friendly takeover. It wouldn’t matter because they’re really down to, as they say, fumes. They have no energy, they have no money. They are in deep trouble on a humanitarian basis, and we really don’t want to see that,” the U.S. president said.
The president also argued that the Cuban government had long depended heavily on support from Venezuela, particularly oil supplies.
According to Trump, that support has been drastically reduced following measures adopted by Washington.
“They were living off Venezuela. Venezuela doesn’t send them energy, fuel, oil, money, or anything anymore. They couldn’t survive without Venezuela, they couldn’t have made it, and we cut everything off,” Trump said.
