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.

Protests persist in Uruapan after mayor’s assassination as citizens demand justice
Five days after the assassination of Carlos Manzo, the mayor of Uruapan in the western state of Michoacán, and following the appointment of his widow, Grecia Quiroz, as interim mayor, hundreds of people continue protesting for the third consecutive day demanding justice.
On Wednesday, around 200 vehicles belonging to transport associations and business owners blocked roads in central Uruapan and several major avenues across the city.
Meanwhile, in Morelia, the state capital, two university marches were scheduled. Demonstrations since Monday have been marked by clashes, police response, and protesters forcing their way into the Michoacán Government Palace.
About 200 kilometers away, in the port city of Lázaro Cárdenas, another demonstration was called for 6:00 p.m. local time, in which the Association of Producers and Exporting Packers of Avocado of Mexico (APEAM) announced it would join the demand for greater security.
Total Shutdown Planned in Uruapan
Local business chambers and organizations in Uruapan have called for a “total shutdown of activities” this Friday, the 7th, at 10:00 a.m. (16:00 GMT). They are urging residents to place a black ribbon at the entrance of their homes or businesses as a sign of mourning.
The groups plan to march wearing black or white shirts under the slogan: “For those who are gone, for those who are afraid, for those who remain standing.”

Sexual assault attempt on Mexico’s president sparks outrage in historic center
A man harassed and groped Mexican President Claudia Sheinbaum without her consent on Tuesday while she walked through Mexico City’s historic center, just meters from the National Palace, greeting members of the public.
The man, who appeared to be intoxicated, attempted to kiss the president from behind before grabbing her. Security personnel immediately intervened and detained him, with video footage showing Sheinbaum visibly tense following the incident.
Sheinbaum was on her way to the first National Meeting of Universities and Higher Education Institutions at the Education Secretariat headquarters, located just a few blocks from the palace. She chose to walk to the event due to the short distance.
During the stroll, in one of the busiest parts of the capital, the man took advantage of the crowd surrounding the president, approaching her from behind, trying to kiss her neck and placing his arms around her.
Hours later, federal authorities confirmed that the suspect — identified as Uriel Rivera Martínez — had been arrested and taken to the Mexico City Prosecutor’s Office for Sexual Crimes, according to the National Detention Registry.
Legal sources stated that Sheinbaum was the victim of a flagrant sexual abuse offense under Mexico City’s Penal Code, noting that no close assistant intervened at the very moment the assault occurred.
According to a 2024 survey by the National Institute of Statistics and Geography (INEGI), 15.5% of women in Mexico have experienced sexual harassment, groping, exhibitionism or attempted rape — five times the percentage of men, at 3.2%.

Longest government shutdown in U.S. history deepens airport and aid crisis
The U.S. government shutdown reached a historic milestone on Wednesday, becoming the longest in the nation’s history as Republicans aligned with President Donald Trump continue to clash with Democratic opposition over the federal budget.
The shutdown entered its 36th day, surpassing the previous record set in 2019 during Trump’s first term in office.
Over the past six weeks, the budget impasse has left roughly 1.4 million federal workers without pay. Employees deemed “essential,” including air traffic controllers and law enforcement officers, have been required to continue working despite not receiving their salaries.
Conditions at airports are growing increasingly strained. Transportation Secretary Sean Duffy warned that the federal government may be forced to partially shut down U.S. airspace due to staffing shortages.
“So if we go another week from now, Democrats, you will see massive chaos… you will see massive flight delays,” Duffy cautioned.
Social assistance programs have also been disrupted. On Tuesday, Trump stated that food aid relied upon by millions of Americans would not be distributed until the government reopens — contradicting earlier administration comments indicating that partial benefits could still be provided.
