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.

U.S. Issues Urgent Evacuation Call for Citizens in Venezuela
The U.S. Department of State on Saturday urged American citizens currently in Venezuela to leave the country “immediately,” citing an increasingly unstable security situation.
In a security alert, the State Department warned of reports involving armed militia groups, known as colectivos, that have set up checkpoints and are stopping vehicles to search for evidence of U.S. citizenship or support for the United States.
The warning comes one week after U.S. forces captured Venezuela’s ousted president, Nicolás Maduro, and his wife, Cilia Flores, during a bombing operation in Caracas. Both were transferred to New York to face trial on narcotics trafficking charges.
U.S. authorities emphasized that the volatile security environment poses significant risks to American nationals and reiterated their long-standing advisory against travel to Venezuela.

U.S. strike in Caracas killed 32 cuban security officers, experts say surprise was crucial
Two days after a U.S. military attack on a military complex in Caracas, Havana confirmed that 32 members of its security forces were killed in the operation, some of whom were likely responsible for protecting Venezuelan leader Nicolás Maduro. The Venezuelan government also reported that 23 of its own military personnel died during the assault.
Of the Cuban dead, 21 belonged to the Ministry of the Interior, which oversees intelligence services, and 11 were from the Revolutionary Armed Forces. No official information has been released regarding potential injuries.
Experts consulted by AFP agreed that the element of surprise was the key to the success of the U.S. military operation, which was meticulously prepared over months and kept entirely secret. “Cuban intelligence … convinced the Maduro regime and its security agencies that the United States would never attack Venezuelan territory,” explained José Gustavo Arocha, a former Venezuelan army officer and expert at the Center for a Secure Free Society, a U.S. defense think tank.
Fulton Armstrong, a former U.S. intelligence officer and Latin America researcher at American University in Washington, also highlighted the failure to anticipate the attack and to detect U.S. helicopters entering Venezuelan airspace, noting that even a five- to ten-minute warning could have made a significant difference for the guards and for Maduro.
U.S. forces additionally benefited from “incredible” real-time intelligence provided by stealth drones to monitor movements of the Venezuelan leader, according to experts. A highly sophisticated combat team was deployed, and analysts believe the order to “fire to kill” was likely given.
Paul Hare, former British ambassador to Cuba and Venezuela, added that Cuban intelligence also underestimated the extent of U.S. access to internal cooperation within Venezuela’s security apparatus, contributing to the operation’s success.

Report: Vatican mediation included russian asylum offer ahead of Maduro’s capture
The Vatican reportedly attempted to negotiate an offer of asylum in Russia for Venezuelan President Nicolás Maduro before his capture by U.S. forces last Saturday, according to The Washington Post.
The U.S. newspaper reported that Vatican Secretary of State Cardinal Pietro Parolin spoke with U.S. Ambassador to the Holy See Brian Burch about a supposed Russian proposal to grant Maduro asylum. A source familiar with the offer said that what was proposed “was that he would leave and be able to enjoy his money,” and that part of the plan involved Russian President Vladimir Putin guaranteeing Maduro’s security.
Despite these diplomatic efforts, the United States carried out a military operation that resulted in Maduro’s capture and detention, along with his wife Cilia Flores, who are now being held in New York on narcoterrorism charges.
The Washington Post also noted that U.S. President Donald Trump may have invited Maduro to Washington for in-person discussions about safe conduct, an offer that Maduro reportedly declined.
