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.

Venezuela Earthquake Death Toll Rises to 4,490 as Rescue Efforts Continue
The death toll from the powerful earthquakes that struck Venezuela on June 24 has risen to 4,490, according to the latest official figures released by the government on social media.
Authorities reported that 16,740 people have been injured, while more than 19,500 residents remain in temporary shelters after the twin earthquakes devastated Caracas and the neighboring state of La Guaira.
Rescue teams from Venezuela and several foreign countries continue searching through collapsed buildings in an effort to recover victims who remain trapped beneath the rubble.
Government officials said the earthquakes damaged more than 850 buildings, with 190 structures completely collapsing.
Thousands of families who lost their homes are currently staying with relatives or friends, while more than 19,500 displaced people are living in overcrowded emergency camps set up in parks, stadiums, and public squares across La Guaira and Caracas.

Tensions Escalate in Middle East as U.S. Bombs Iran After Maritime Attacks
The United States launched new strikes against Iran on Wednesday, following President Donald Trump’s warning that Washington would “hit hard” against the Islamic Republic. While Trump ordered the retaliation after attacks on vessels in the Strait of Hormuz, he also said he hoped the latest wave of bombings would end soon and left the door open for renewed negotiations.
U.S. forces “have begun carrying out additional strikes against Iran to further reduce its ability to threaten freedom of navigation in the Strait of Hormuz,” the United States Central Command said in a post on X.
Washington blamed Iran for what it described as “recent unjustified aggression against commercial shipping.”
Iran’s state news agency IRNA reported that explosions were heard in the port cities of Bandar Abbas, Konarak, and Chabahar.
“This is in retaliation for yesterday’s bombing of ships by Iran. If it happens again, it will be much worse,” Trump wrote on social media alongside an image showing what appeared to be a bombing at an Iranian location.
Before ordering the strikes, the U.S. president said that the ceasefire with Iran had ended. Mediators Pakistan and Qatar called for de-escalation, while the United Nations also urged both sides to reduce tensions.
The Strait of Hormuz remains a critical flashpoint in the Middle East conflict, which began in late February after U.S. and Israeli strikes that killed Iran’s Supreme Leader Ali Khamenei.
Iran-linked attacks on at least three vessels in recent days triggered a U.S. offensive against Iranian targets on Tuesday. Tehran responded by launching attacks against Gulf countries that are allies of Washington.

Deadly Drug Trade Rivalry Suspected After Eight Bodies Discovered in Southern Mexico
Eight bodies were found Wednesday along a highway in the southern Mexican state of Chiapas, near the border with Guatemala, in an incident authorities believe may be linked to a dispute over local drug sales.
The victims — six men and two women — were found abandoned on a road in a mountainous area of the municipality of El Bosque, according to the state prosecutor’s office in a statement published on Facebook.
Initial investigations indicate that the killings may be connected to “a dispute over retail drug sales between local criminal groups operating in the region,” the prosecutor’s office said.
Local media reports that several criminal incidents have increased in the area since the beginning of the year.
The road where the bodies were discovered is located in a mountainous region largely inhabited by Indigenous communities. Authorities have not released further details about the victims or possible suspects as the investigation continues.
