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.

Trump: U.S. has hit three venezuelan narco boats in Caribbean
U.S. President Donald Trump said Tuesday that American forces have struck three suspected Venezuelan drug-trafficking vessels in the Caribbean so far, not two as previously reported.
“We took down boats. It was actually three boats, not two, but you only saw two,” Trump told reporters at the White House before departing for a state visit to the United Kingdom.
The president was asked about remarks by Venezuelan leader Nicolás Maduro, who accused Washington of plotting to invade his country.
“Stop sending members of the Tren de Aragua to the United States. Stop sending drugs to the United States,” Trump responded.
The Republican leader mentioned this third vessel a day after announcing that U.S. forces had struck a speedboat in which, according to him, three “terrorists” were killed. Later, from the Oval Office, he claimed the boat had been carrying cocaine and fentanyl.
The attacks come amid escalating tensions between Washington and Caracas, as the U.S. military maintains a Caribbean deployment under the banner of counter-narcotics operations.
The Trump administration accuses Maduro of heading the so-called Cartel of the Suns, which the Venezuelan government denies. Washington has also offered a $50 million reward for information leading to Maduro’s capture.
On Monday, Maduro said communications with the U.S. were “broken” in the face of what he called an “aggression” and declared that Venezuela is now “better prepared” in case of an “armed struggle.”

Ecuador’s Noboa declares State of Emergency in seven provinces amid fuel price protests
Ecuadorian President Daniel Noboa declared a state of emergency on Tuesday in seven provinces due to what he described as “serious internal unrest,” as road blockades and demonstrations erupted in response to the elimination of the diesel subsidy and growing concerns over insecurity.
The 60-day measure applies to the provinces of Carchi, Imbabura, Pichincha, Azuay, Bolívar, Cotopaxi, and Santo Domingo de los Tsáchilas.
Since Monday, partial protests have been reported in Pichincha, Carchi, Azuay, and Imbabura. On Tuesday, road blockades extended to northern Pichincha and routes in Carchi, near the Colombian border. In response, the Executive headquarters was temporarily relocated to Cotopaxi and the Vice Presidency to Imbabura.
The presidential decree states that the measure comes amid “strikes that have disrupted public order and provoked acts of violence, endangering the safety of citizens and their rights to free movement, work, and economic activity.”
According to the decree, the goal is to “prevent the radicalization of disruptive actions” in the affected provinces and to limit the impact on the population. It further emphasizes that the situation requires an “exceptional intervention by state institutions to safeguard security, guarantee citizens’ rights, maintain public order, and preserve social peace.”
Social organizations and labor groups, including the Confederation of Indigenous Nationalities of Ecuador (Conaie), have strongly rejected the diesel price increase following the subsidy’s elimination.
The decree justifies the two-month duration as necessary “to ensure a strengthened state presence in the affected territories, restore order, and prevent further acts of violence against people, public, and private property.”

Colombia’s special peace tribunal hands down first sentence against former FARC leaders
Seven former rebel leaders, including their last known commander Rodrigo Londoño, alias “Timochenko,” have been handed the maximum penalty established in the 2016 peace agreement.
Under the ruling, they will face mobility restrictions and be required to carry out activities aimed at restoring the dignity of victims, such as helping locate missing persons and participating in landmine clearance in territories where they once operated. These alternative sentences to prison were part of the historic deal signed in 2016 between the Revolutionary Armed Forces of Colombia (FARC) —once the most powerful guerrilla group in Latin America— and then-President Juan Manuel Santos, Nobel Peace Prize laureate.
The Special Jurisdiction for Peace (JEP) found the ex-commanders guilty of being responsible for the kidnapping of 21,396 people before laying down their arms and transitioning into a political party. “Investigations showed that kidnapping became a systematic practice. These crimes not only broke the law but also left open wounds that persist in families, communities, and the daily life of the country,” a magistrate told reporters in Bogotá, in the absence of the former commanders, who had accepted responsibility for their crimes back in 2022.
It took the tribunal more than seven years to deliver its first ruling, amid criticism from opponents of the peace deal who argue it is too lenient on the rebels. The former commanders still face charges for other crimes against humanity, including the recruitment of minors.
During their decades-long conflict, the FARC held hostage soldiers, police officers, businesspeople, and political leaders, including French-Colombian Ingrid Betancourt. Images of emaciated captives chained in jungle camps shocked the world and became symbols of the conflict.
