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.

President Noboa Declares New Security Strategy as Ecuador Faces Record Violence Levels

Ecuadorian President Daniel Noboa on Tuesday declared the National Comprehensive Security Plan 2025-2029 as a nationwide public policy, a strategy aimed at guiding state actions on security matters over the next four years.

The measure was formalized through an executive decree that activates the plan approved on March 9 by the Public and State Security Council (Cosepe) and replaces the National Comprehensive Security Plan 2019-2030, which had been designated as public policy in 2021.

Under the new decree, implementation of the strategy will be led by the ministries of Interior, Defense, and Foreign Affairs and Human Mobility, along with the National Intelligence Center and the National Secretariat for Risk Management. These institutions will be responsible for coordinating actions according to their respective areas of responsibility.

According to the official document, the new plan adopts a multidimensional and comprehensive security approach, with a long-term vision focused on national interests and on strengthening the State’s ability to respond to current threats.

The Ecuadorian government said the strategy seeks to improve coordination among public institutions within the framework of the “internal armed conflict” declared by Noboa in 2024 as part of the fight against criminal organizations operating across the country.

The plan also includes measures to strengthen international cooperation against transnational organized crime, which authorities identify as one of Ecuador’s main security challenges due to its links to drug trafficking and illegal mining.

The government described the document as a roadmap for prevention, protection, response and recovery actions in the face of national security risks, promoting coordinated efforts among state institutions.

Ecuador has remained under an internal armed conflict declaration since 2024, when Noboa intensified operations against criminal gangs that his administration has labeled terrorist organizations. Despite the increased security measures, the country recorded around 9,300 homicides in 2025, the highest figure in its history, according to data from the Ministry of Interior.

The new security plan comes as Ecuador seeks to strengthen its institutional response to escalating violence and the growing influence of organized crime networks.

Foreign Medical Teams Race to Prevent Health Crisis in Venezuela Earthquake Camps

More than two weeks after the twin earthquakes that devastated parts of Venezuela and left thousands of people without homes, medical teams from several countries are working to prevent a potential health crisis in temporary shelters where survivors are living in precarious conditions.

The magnitude 7.2 and 7.5 earthquakes that struck on June 24 have left more than 4,561 people dead and 16,740 injured, according to the latest government figures. The hardest-hit area has been La Guaira state, located near Caracas and considered the epicenter of the disaster.

Field hospitals from El Salvador, Mexico, the United States, Brazil and Spain are now facing the challenge of containing respiratory illnesses, gastrointestinal problems and psychological conditions linked to the tragedy.

Among those affected is 54-year-old Darwin López, one of nearly 18,000 Venezuelans who lost their homes and are now living in crowded emergency shelters set up in stadiums, parks, public squares and even sidewalks across La Guaira.

During the first three days after the earthquakes, López focused on rescuing his 44-year-old wife and their three-year-old child from the rubble of the building where they lived.

On Friday, he took another of his children, a 35-year-old man, to a U.S.-operated mobile hospital after he developed severe stomach pain.

“He had a strong stomach ache, and I took him to Pariata Hospital in La Guaira, but it was overwhelmed. So they gave us this alternative,” López told AFP while waiting outside a Samaritan’s Purse field hospital installed in large white tents.

Doctors are now treating him and his family hopes the condition is not serious, although López fears it may have been caused by contaminated food or unsafe water.

In the immediate aftermath of the earthquakes, international medical teams focused primarily on treating severe trauma cases, fractures and performing emergency surgeries. However, their priorities have now shifted toward addressing post-disaster illnesses and implementing epidemiological monitoring programs to reduce the risk of disease outbreaks.

Health authorities and humanitarian organizations warn that overcrowded shelters, limited access to clean water and difficult living conditions could increase the possibility of respiratory and gastrointestinal outbreaks among thousands of displaced survivors.

France Holds Largest Bastille Day Military Parade as Europe Highlights Strategic Defense

France held its largest-ever Bastille Day military parade on Tuesday, with nearly 6,700 troops, 98 aircraft, 31 helicopters and 315 military vehicles marching along the iconic route from the Arc de Triomphe to Place de la Concorde.

The annual parade, held to commemorate the storming of the Bastille prison in 1789, which marked the beginning of the French Revolution, was centered this year on France’s defense capabilities and Europe’s growing security challenges.

According to the Élysée Palace, the event aimed to highlight “France’s rearmament, France’s strategic autonomy and the strategic awakening of Europe.”

Among the main guests in the presidential stand was Ukrainian President Volodymyr Zelensky, who received a warm welcome upon his arrival, including a greeting from French First Lady Brigitte Macron and Prime Minister Sébastien Lecornu.

Zelensky was joined by 24 European heads of state and government, including German Chancellor Friedrich Merz, Spanish Prime Minister Pedro Sánchez, Polish Prime Minister Donald Tusk, Danish Prime Minister Mette Frederiksen and outgoing British Prime Minister Keir Starmer.

The parade also featured military contingents from 35 countries, with around 500 international participants, as well as 25 Ukrainian soldiers who took part in the ceremony.

The event came one day after a new summit in Paris of the so-called “Coalition of the Willing,” a group of countries committed to supporting Ukraine over the long term. Some members of the coalition have considered deploying troops to Ukraine once a ceasefire agreement with Russia is reached.

The large-scale celebration reflected France’s efforts to reinforce its role in European defense and underline unity among allies amid ongoing security concerns across the continent.
