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.

ICE to prioritize security over immigration enforcement during 2026 World Cup, says official

U.S. Immigration and Customs Enforcement (ICE) will prioritize event security and the protection of attendees over immigration enforcement during the 2026 World Cup, according to its director, Tom Homan.

The tournament will be jointly hosted by the United States, Mexico, and Canada from June 11 to July 19, 2026, and is expected to draw millions of visitors across the three countries.

Speaking in an interview with ABC, Homan said the agency’s main responsibility during the competition will be to prevent any security threats that could disrupt one of the world’s largest sporting events.

“We have a national security responsibility that we are going to carry out,” Homan stated, emphasizing that ICE operations during the tournament will focus on intelligence, prevention, and the protection of critical infrastructure rather than immigration enforcement actions targeting undocumented individuals.

He added that the agency’s priority will be safeguarding players, teams, fans, and stadiums throughout the event.

However, Homan clarified that immigration status could still be taken into account in cases where national security concerns arise. “If we find a national security issue and it involves an illegal alien, of course we will take action,” he said.

The comments came in response to questions about concerns from international visitors regarding possible immigration enforcement activity during the tournament.

Homan reiterated that ICE’s operational focus will remain strictly on security-related matters. Known as the “border czar” within the U.S. administration, he said the agency will concentrate on preventing risks and ensuring the safety of all participants and spectators.

The 2026 World Cup will be the first edition of the tournament to feature 48 national teams, significantly increasing travel and logistical demands across the host nations. As a result, authorities are coordinating extensive security preparations involving federal, state, and international agencies.

Officials have described the tournament as one of the most complex security and organizational challenges ever undertaken in North America, with preparations already underway to ensure its safe and orderly execution.

Two Police Officers Shot During Road Clearance Operation in Eastern Bolivia

At least two police officers were wounded by gunfire on Saturday during an operation to clear roadblocks in Bolivia’s eastern Santa Cruz region, which has remained partially cut off for 24 days amid protests demanding the resignation of President Rodrigo Paz.

The joint operation involving the Police and the Armed Forces began at 6:00 a.m. local time near the town of San Julián, approximately 117 kilometers northeast of Santa Cruz city. The effort focused on reopening an alternative highway linking the region with Beni and western Bolivia.

According to Santa Cruz Police Commander David Gómez, protesters initially responded aggressively to the security operation.

“Local groups organized themselves and began attacking us brutally with firecrackers, stones, and other objects,” Gómez told reporters. “We used chemical agents in an attempt to disperse the crowd, which was behaving aggressively.”

Authorities initially succeeded in reopening the roadway, allowing vehicles to pass through. However, protesters later regrouped and engaged in renewed clashes with police forces that lasted for more than four hours.

During the confrontation, gunshots were heard, forcing both police and military personnel to withdraw from the area.

Gómez reported that one officer suffered a gunshot wound to the head, while another was struck in the right thigh. Both officers were evacuated for medical treatment.

The police commander stated that demonstrators not only carried out physical attacks against officers but also used firearms during the confrontation, prompting authorities to order a tactical retreat.

The incident marks a significant escalation in tensions surrounding the ongoing protests in Santa Cruz, where demonstrators have maintained roadblocks for more than three weeks as part of their campaign against the government.

U.S. to invest $700 million in coal plants and mines under Trump initiative

U.S. President Donald Trump announced on Thursday a $700 million funding package aimed at supporting the American coal industry, marking the latest step in his administration’s efforts to boost the use of the fossil fuel.

According to Trump, the funding will be used to keep 14 coal-fired power plants operating across ten states, maintain 42 coal mines, and support the construction of two new power plants and an export terminal.

The president said the initiative will be financed through the Defense Production Act, a law enacted in 1950 that grants emergency powers to the president to support and direct domestic industries considered critical to national interests.

Since returning to the White House last year, Trump has pursued policies designed to expand domestic energy production and roll back a number of environmental regulations. He has also repeatedly questioned the scientific consensus regarding human-caused climate change.

Coal remains the most carbon-intensive fossil fuel and is the largest source of greenhouse gas emissions among major energy sources, making it a central focus of debates over climate policy and energy security.

U.S. Energy Secretary Chris Wright defended the initiative, describing coal as a critical resource for both electricity generation and industrial production.

The announcement comes as global energy markets continue to evolve. According to an analysis by the Global Energy Monitor, the world added and commissioned more coal-fired power capacity in 2025, although overall coal consumption declined. The report also found that the United States was the only major economy to record a significant increase in coal-fired power generation during that period.

The new funding package underscores the administration’s commitment to supporting traditional energy industries while debate continues over the balance between energy security, economic growth and environmental objectives.
