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.

Nicolás Maduro’s Son Calls U.S. Trial Against His Father and Cilia Flores “Unjust”
Venezuelan lawmaker Nicolás Maduro Guerra on Wednesday described as “unjust” the legal proceedings in the United States against his father, ousted Venezuelan President Nicolás Maduro, and his wife, Cilia Flores, following their capture in Caracas on January 3 by U.S. forces.
“Faced with the unjust trial taking place today, the people raised their voices with a single demand: We demand the immediate release of President Nicolás Maduro and the First Lady,” Maduro Guerra wrote on his Instagram account.
The lawmaker attended a rally in Caracas where supporters of the ruling United Socialist Party of Venezuela (PSUV)gathered to show support for the former president, who faces charges in the United States including conspiracy to commit narco-terrorism and cocaine importation. Flores is accused of crimes related to drug trafficking and weapons possession.
The event was also attended by PSUV Vice President for Mobilizations and Events Nahum Fernández and Caracas Mayor Carmen Meléndez, according to photos shared by Maduro’s son.
The third hearing in the case against Maduro and Flores concluded Wednesday at a federal court in New York after lasting only about 18 minutes. During the hearing, the judge preliminarily set June 2027 as the expected start date for the trial.
One of the main arguments from the defense will focus on immunity. Maduro’s lead attorney, Barry Pollack, who has also represented WikiLeaks founder Julian Assange, said the defense plans to request immunity for both defendants, arguing that Maduro was serving as head of state and Flores as first lady at the time of their detention.
Both Maduro and Flores pleaded not guilty during their first court appearance in New York on January 5.
Meanwhile, Venezuela’s interim president Delcy Rodríguez, who assumed power after Maduro’s capture, has not yet commented on Wednesday’s hearing in the United States.

Mexico Files 20 Complaints in U.S. Over Deaths of 17 Citizens During ICE Operations
The Mexican government announced that it has filed 20 legal complaints across different jurisdictions in the United States seeking investigations into the deaths of 17 Mexican citizens who died since May 2025 during immigration enforcement operations or while in the custody of the U.S. Immigration and Customs Enforcement (ICE).
Mexico’s Secretariat of Foreign Affairs (SRE) reported that the complaints were submitted on July 13 by Mexico’s ambassador to the United States, Roberto Lazzeri. Of the total, eight cases were filed with state prosecutors’ offices and 12 with county prosecutors’ offices in Arizona, California, Florida, Georgia, Illinois, Louisiana, Missouri, and Texas.
According to the Mexican government, the legal actions seek to clarify the circumstances surrounding each death and determine whether any immigration authorities may bear responsibility.
During meetings with representatives from the Department of Homeland Security (DHS) and ICE, Ambassador Lazzeri expressed Mexico’s concerns over conditions in immigration detention centers, including privately operated facilities, and requested thorough investigations into every case.
In addition to the complaints filed in the United States, Mexico’s Foreign Affairs Ministry sent a communication to United Nations High Commissioner for Human Rights Volker Türk, informing him of the deaths and requesting that the UN gather information, assess the situation under international human rights standards, and issue recommendations to prevent similar incidents.
The SRE also stated that Mexico’s consular network continues to provide support to the families of the deceased citizens, including legal assistance, help with repatriation of remains, and other procedures requested by relatives.
The announcement comes after the death of Lorenzo Salgado Araújo, a Mexican citizen who died after being shot by ICE agents during an immigration operation in Texas. The case has gained additional attention after a federal judge in Houston ordered a halt to the deportation of José Trinidad Rojas Pliego, considered a key witness in the incident.
Mexican authorities reiterated that they will continue using all available legal and diplomatic mechanisms to monitor the investigations and defend the rights of Mexican citizens in U.S. territory.

India Approves New Dengue Vaccine as Global Cases Continue to Rise
India has approved a new dengue vaccine as health authorities seek to strengthen prevention efforts against a mosquito-borne viral disease that affects millions of people worldwide every year.
According to the World Health Organization (WHO), half of the global population is currently at risk of contracting dengue, which causes between 100 million and 400 million infections annually.
Since 2021, India has recorded more than one million dengue cases, including at least 1,500 deaths.
The virus can cause high fever, severe headaches, muscle pain, nausea, skin rashes and, in rare cases, internal bleeding and death.
The vaccine, authorized by India’s Central Drugs Standard Control Organization (CDSCO), was developed by Japanese pharmaceutical company Takeda. The Indian Health Ministry said the vaccine is recommended in two doses for people between 4 and 60 years old.
The treatment has already been approved by health authorities in around 40 countries worldwide.
Meanwhile, Indian pharmaceutical company Panacea Biotec has begun the final phase of clinical trials for a single-dose dengue vaccine, aiming to provide another prevention option against the disease.
Brazil recently announced the suspension of the use of another single-dose dengue vaccine developed in the country after two suspected deaths were reported.
