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.

Spain’s irregular migrant population rises to 840,000, study finds
The number of migrants living in Spain without legal residency status continues to rise and has reached 840,000 people, with 91% originating from the Americas, particularly Colombia, Peru and Honduras, according to a report by the Spanish think tank Funcas (Foundation of the Savings Banks).
An estimated 17.2% of the non-EU foreign population living in Spain is in an irregular administrative situation. The estimate is based on the gap between the number of foreign residents effectively living in Spain, according to the National Statistics Institute (INE), and those who hold a residence permit, benefit from international protection, or are in the process of obtaining it.
The data, as of January 1, 2025, point to a notable and sustained increase in irregular migration since 2017, when the estimated figure stood at around 107,000 people, representing 4.2% of the non-EU population residing in Spain.
By origin, migrants from the American continent stand out, totaling around 760,000 people, or 91% of all irregular migrants. Colombians account for nearly 290,000, followed by Peruvians with almost 110,000, and Hondurans with about 90,000. Migrants from Africa (50,000), Asia (15,000) and Europe (14,000) trail far behind.
The figures predate Spain’s latest immigration regulation reform, which came into force in May 2025 and introduces measures to ease access to legal status through residency ties. According to Funcas, the reform would, in principle, tend to reduce the number of migrants in an irregular situation.

Historic snowstorm paralyzes Toronto after 60 centimeters of snow
Toronto, Canada’s largest city and the fourth most populous in North America, was largely paralyzed on Monday after a historic snowstorm dumped up to 60 centimeters of snow and sent temperatures plunging to -15 degrees Celsius, authorities said.
Late Sunday, as the scale of the snowfall became clear, city officials declared a climate emergency, triggering extraordinary measures including parking bans on several major streets to facilitate snow removal operations.
Toronto’s public transit authority reported that while some buses remain immobilized, subway and streetcar services are operating with relative normality, though localized disruptions may occur.
A similar situation is affecting the city’s commuter rail network, which remains operational but is experiencing significant delays on its main routes due to the severe weather conditions.

Venezuela frees at least 80 political prisoners, NGO says
At least 80 political prisoners were released on Sunday across Venezuela, human rights group Foro Penal reported, as the broader process of detainee releases continues at a slow pace under the interim government.
Foro Penal’s director, Alfredo Romero, wrote on social media platform X that verified releases took place nationwide and that the figure could rise as more confirmations are completed.
Attorney Gonzalo Himiob, also from Foro Penal, said the excarcelations occurred during the early hours of the day and emphasized that the number is not yet final pending further verification.
The releases are part of a series of steps announced by Venezuela’s interim leader, Delcy Rodríguez, who took power after the capture of former President Nicolás Maduro in a U.S. military operation on Jan. 3, 2026. Rodríguez has pledged a significant number of liberations but has been criticized by opposition groups and rights organizations for the slow and nontransparent nature of the process.
So far, the Venezuelan government reports that 626 detainees have been freed since December, though independent counts by human rights groups suggest the number of actual political prisoner releases is lower and that many remain behind bars.
Families of those still detained have maintained vigils outside prisons, hopeful for further releases even as broader concerns about political imprisonment and due process persist.
