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.

Claudia Sheinbaum: Operation Against ‘El Mencho’ Was Based on Pending Arrest Warrants
Mexico’s President Claudia Sheinbaum on Wednesday rejected claims that the military operation that resulted in the death of Nemesio Oseguera Cervantes, known as “El Mencho,” leader of the Jalisco New Generation Cartel (CJNG), was carried out under pressure from the United States government.
Sheinbaum explained that the deployment of federal forces was aimed at executing outstanding arrest warrants against Oseguera Cervantes, who was considered one of the most wanted criminals in both Mexico and the United States.
“That was not the objective (to ease pressure from the United States). It is very important, and I want to repeat it. This individual had an arrest warrant, or several,” Sheinbaum said, referring to the operation conducted on February 22.
According to the president, the initial goal was to capture Oseguera Cervantes, but military forces responded after coming under attack during the intervention.
“The operation was to detain him. The problem is that they were attacked — the Secretariat of National Defense — and they responded at that moment,” she said.
The president insisted that the action was not carried out in response to external demands, although she acknowledged intelligence cooperation with the United States.
“It was not done in any way because of pressure from the United States, not at all. Of course, there was intelligence information from the United States that was used specifically,” she concluded.

Spain Denies Any Agreement to Cooperate with U.S. Military in Iran Operations
Spain’s Foreign Minister José Manuel Albares on Wednesday firmly denied that Madrid has agreed to cooperate with the U.S. military in operations against Iran, contradicting statements made minutes earlier by White House Press Secretary Karoline Leavitt.
“I categorically deny it,” Albares said in a radio interview cited by EFE. “The position of the Spanish government regarding the war in the Middle East, the bombings in Iran, and the use of our bases has not changed by a single comma.”
Earlier in the day, Leavitt told reporters that Spain had “agreed to cooperate with the United States military in recent hours,” following President Donald Trump’s threat to impose a trade embargo on Madrid. Trump had warned of economic measures after Spain reportedly refused to allow the Pentagon to use facilities at Spanish bases for operations related to Iran.
“I have no idea what that could be referring to or where it could be coming from,” Albares said, insisting that Spain’s position “has not changed at all” and therefore “remains absolutely unchanged.” He added that he had “no desire” and “almost no time” to speculate about the White House spokesperson’s remarks.
Albares reiterated Spain’s “No to war” stance, which he said had been clearly and forcefully expressed by Prime Minister Pedro Sánchez in an institutional address. According to the foreign minister, that position has been supported by “many European colleagues.”

White House Says Spain Agrees to Cooperate with U.S. Military After Trump Threatens Trade Embargo
White House Press Secretary Karoline Leavitt said Wednesday that Spain has agreed “in recent hours” to cooperate with the U.S. military, following President Donald Trump’s threat to impose a trade embargo on Madrid.
Trump had warned of potential commercial measures after Spain reportedly refused to allow the Pentagon to use facilities at Spanish military bases for operations related to Iran.
“With respect to Spain, I think you heard the president’s message yesterday loud and clear, and I understand that in recent hours they have agreed to cooperate with the United States military,” Leavitt said during a press briefing.
She added that the U.S. military is currently coordinating with its counterparts in Spain. However, the president expects broader support.
“The president expects that all of Europe, all of our European allies, of course, will cooperate in this important mission — not only for the United States, but also for Europe,” Leavitt said.
Her remarks came in response to questions about Spain’s position and its role as a U.S. ally amid rising tensions surrounding operations involving Iran.
