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.

U.S. Proposes Higher Citizenship Fees and Limits on Immigration Fee Waivers

The U.S. Department of Homeland Security (DHS) has proposed increasing fees related to citizenship applications, while also seeking changes to programs that reduce or waive immigration-related costs for certain applicants.

The proposal would eliminate fee waivers and reduced-fee programs for immigrants whose household incomes are at or below 400% of the federal poverty level.

However, the changes would not take effect immediately. Before receiving final approval, the proposal must go through a 60-day public comment period, allowing individuals and organizations to submit feedback.

DHS justified the proposed increases by stating that the goal is to fully cover the costs associated with processing citizenship and naturalization applications.

“Although the Department of Homeland Security has historically limited form fees to promote naturalization, the agency no longer considers that these applications should have lower costs at the expense of other immigration benefits,” the department said in the proposal document.

If approved, the reform would modify the current immigration fee structure and could impact thousands of applicants who rely on financial assistance programs to complete their citizenship process.

U.S. authorities said the measure is part of a broader review of immigration service fees and the mechanisms used to fund the administration of these programs.

Cristiano Ronaldo Makes History as First Player to Score in Six World Cups

Cristiano Ronaldo made football history on Tuesday by becoming the first player ever to score in six different editions of the FIFA World Cup.

The Portuguese forward opened the scoring in Portugal’s Group K match against Uzbekistan in Houston. Just six minutes into the game, Ronaldo found the back of the net with a right-footed strike from inside the box, sending the Portuguese fans into celebration.

The “Commander” sparked excitement throughout the stadium with his iconic celebration, as supporters joined in with his famous “Siuuu!” chant to honor another milestone in the career of one of football’s greatest stars.

At 41 years old, Ronaldo has now scored in Germany 2006, South Africa 2010, Brazil 2014, Russia 2018, Qatar 2022, and North America 2026. With his two goals in this tournament, he has surpassed Lionel Messi’s record, as the Argentine has scored in every World Cup he played except South Africa 2010.

The Portuguese captain has also reached nine World Cup goals, matching Eusébio as Portugal’s all-time top scorer in the history of the tournament.

Ronaldo’s achievement came just one day after Messi also made history by becoming the outright leading scorer in World Cup history, reaching 18 goals after scoring twice in Argentina’s 2-0 victory over Austria.

With his appearance at the 2026 World Cup, Cristiano Ronaldo has also extended another remarkable record by becoming the first player to participate in six consecutive editions of the tournament, further cementing his legacy as one of the most influential players in football history.

Mbappé Ties Klose on All-Time World Cup Scoring List After Brace Against Iraq

Kylian Mbappé moved another step closer to World Cup history on Monday, scoring twice against Iraq to reach 16 career goals in the tournament and draw level with German legend Miroslav Klose on the all-time scoring chart.

The French forward found the net in the 14th and 54th minutes of France’s Group I clash in Philadelphia, registering his second consecutive brace of the 2026 FIFA World Cup.

Mbappé’s achievement came on the same day that Argentina captain Lionel Messi set a new all-time World Cup scoring record. The Argentine star scored twice against Austria to raise his career total to 18 goals, surpassing the previous mark of 16 held by Klose.

Klose established his record on July 8, 2014, during Germany’s historic 7-1 victory over Brazil in the World Cup semifinals in Belo Horizonte.

Before facing Iraq, Mbappé was tied with German striker Gerd Müller on 14 World Cup goals. His first goal of the match lifted him to 15, drawing level with Brazilian great Ronaldo Nazário.

The second strike moved the Real Madrid forward to 16 goals, allowing him to surpass Ronaldo, match Klose’s tally, and position himself just two goals behind Messi in the race for World Cup immortality.

The match also marked a personal milestone for Mbappé, as he made his 100th appearance for the French national team.

At 27 years old, the French superstar remains firmly in pursuit of Messi’s newly established record and continues to strengthen his legacy as one of the most prolific scorers in World Cup history.
