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.

Mexico, Brazil and Colombia left out of Trump’s “Shield of the Americas” summit
Left-wing governments in Latin America, including Mexico, Brazil and Colombia, were excluded from the “Shield of the Americas” summit convened by U.S. President Donald Trump.
The meeting, held in Miami, Florida, brought together 12 presidents from across the continent to discuss strategies to combat drug cartels and organized crime.
In Mexico’s case, President Claudia Sheinbaum had recently rejected the use of military force as a solution to the drug trafficking problem. She has argued that her administration’s security strategy is producing results and emphasized that force alone is not the answer.
During the summit, Trump said that most narcotics entering the United States come through Mexico and referred to his previous conversations with Sheinbaum on the issue.
“I like the president very much, she’s a very good person,” Trump said. “But I told her: ‘Let me eradicate the cartels.’ And she said, ‘No, no, no, please, president.’ We have to eradicate them. We have to finish them.”
The remarks highlighted ongoing differences between Washington and Mexico over how to confront drug trafficking networks operating across the region.

Trump announces 17-nation alliance in the Americas to “destroy” drug cartels
U.S. President Donald Trump announced on Saturday the creation of a 17-nation alliance across the Americas aimed at dismantling drug cartels, during a regional summit held at his golf club in Doral.
Speaking to a group of allied leaders at the Shield of the Americas Summit, Trump said the initiative would rely on military force to eliminate powerful criminal networks operating throughout the hemisphere.
“The heart of our agreement is the commitment to use lethal military force to destroy these sinister cartels and terrorist networks. Once and for all, we will put an end to them,” Trump told the assembled heads of state.
The Republican leader argued that large portions of territory in the Western Hemisphere have fallen under the control of transnational gangs and pledged U.S. support to governments seeking to confront them. He even suggested the potential use of highly precise missiles against cartel leaders.
Before making the announcement, Trump greeted the roughly twelve leaders attending the summit, including close allies such as Javier Milei, Daniel Noboa and Nayib Bukele, whom he described as a “great president.”
The meeting forms part of Trump’s broader regional strategy inspired by his reinterpretation of the Monroe Doctrine, which seeks to reinforce Washington’s influence in the Americas, strengthen security cooperation and counter the growing presence of powers such as China.
Trump pointed to recent U.S. actions in the region as examples of his administration’s approach, including the operation that led to the capture of former Venezuelan president Nicolás Maduro earlier this year.
The summit also takes place amid escalating international tensions following the conflict launched last week by the United States and Israel against Iran.

Trump replaces Homeland Security Secretary Kristi Noem with Senator Markwayne Mullin
U.S. President Donald Trump announced Thursday the departure of Kristi Noem as Secretary of Homeland Security, one of the key architects of the administration’s policy of deporting undocumented immigrants.
Noem, who has been assigned a new role as a “special envoy” to Latin America, will be replaced starting March 31 by Republican Senator Markwayne Mullin, the president said in a message posted on his social media platform Truth Social.
According to media reports, Trump made the decision after Noem’s recent hearings in Congress, during which she faced tough questions regarding the awarding of a major public contract.
