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.

Ombudsman confirms deaths of six minors in bombing targeting FARC dissidents
Colombia’s Ombudsman’s Office reported on Saturday the deaths of six minors who had been recruited by guerrilla groups, killed during the deadliest airstrike ordered by President Gustavo Petro in an Amazonian region in the south of the country.
Amid pre-election criticism and pressure from the United States demanding stronger action against drug trafficking, Petro has intensified military operations against armed groups. Over the past week, a series of bombings have left 28 people dead.
The minors were killed in an airstrike announced on Tuesday against a camp belonging to dissident factions of the now-defunct FARC guerrilla in the department of Guaviare, resulting in 19 deaths—the largest operation of its kind under Petro’s administration.
“This is all deeply regrettable; it is war in its most painful and inhumane expression, harming the most vulnerable—minors recruited due to lack of protection and now turned into military targets,” said Ombudswoman Iris Marín in an audio message sent to the press, confirming the deaths of six minors without providing their ages.
Marín held the guerrilla group led by the country’s most-wanted man, alias Iván Mordisco, responsible for recruiting the children.
However, she also stressed that “the military forces must take every feasible precaution to protect children,” in accordance with international principles that require “careful evaluation of the means and methods of warfare to avoid disproportionate or unnecessary harm.”

Colombia reaches $4.5 billion deal to acquire 17 Gripen Fighter Jets from Saab
The Colombian government has finalized a negotiation agreement with the Swedish company Saab for the purchase of 17 SAP-39 Gripen fighter jets, valued at more than $4.5 billion, according to local media reports.
Colombian outlets indicated that payments are scheduled to begin in 2026, starting with an initial installment of 100 billion Colombian pesos. However, the aircraft will be delivered between 2027 and 2032, when the final jet is expected to arrive in Colombia.
This new contract represents the second-largest public purchase made by Colombia so far this century, surpassed only by the investment in the Bogotá metro system, local media noted.
The agreement is expected to be officially signed during the ceremony commemorating the 216th anniversary of the Colombian Aerospace Force, to be held in Cali on November 14 of this year.

Venezuela accuses U.S. of using Naval Deployment to pressure Maduro government
The world’s largest aircraft carrier, the USS Gerald R. Ford, joined the U.S. Navy’s anti-drug operation in Latin America on Tuesday—a deployment Venezuela has condemned as an attempt to pressure President Nicolás Maduro from power.
In a statement, the U.S. Southern Command confirmed that the carrier, ordered to deploy nearly three weeks ago, has entered its area of responsibility, which includes Latin America and the Caribbean.
“The world’s largest aircraft carrier will strengthen the United States’ ability to detect, monitor, and dismantle illicit actors and activities that threaten the security and prosperity of U.S. territory and our safety in the Western Hemisphere,” said Pentagon spokesperson Sean Parnell.
According to the White House, the U.S. government under Donald Trump has carried out about twenty operations in the Caribbean and the Pacific since early September, resulting in the deaths of 76 suspected drug traffickers.
However, U.S. authorities have not yet presented evidence that the targeted vessels were being used for drug trafficking or posed a direct threat to the country.
The operations have raised concerns in Caracas, where the Maduro administration views the deployment as a strategic move aimed at provoking regime change in Venezuela.
