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.

Authorities Say Teotihuacán Gunman Was Obsessed With Mass Shootings and Extremist Symbolism
Julio César Jasso Ramírez, identified by authorities as the gunman behind the armed attack at the archaeological site of Teotihuacán, had allegedly spent years building a personal narrative shaped by an obsession with historical mass shootings, extremist symbolism, and an increasing detachment from reality.
According to preliminary findings from the Fiscalía General de Justicia del Estado de México, the 27-year-old suspect, originally from the southern Mexican state of Oaxaca, acted alone and appeared to have carefully planned the attack.
Investigators also pointed to signs of a severe psychological or psychiatric disorder. One official involved in the case stated that the suspect seemed to live in “his own reality,” disconnected from the world around him.
“I would not speak of a motive; I would speak of psychopathy, a condition, an illness,” the official said while discussing the ongoing investigation.
Authorities reported that Jasso Ramírez was allegedly fixated on mass violence incidents that occurred outside Mexico, particularly in the United States.
Among the items found in his possession were writings, images, and materials reportedly linked to the Columbine High School massacre, the school shooting that took place on April 20, 1999.
The investigation remains ongoing as authorities continue analyzing evidence connected to the suspect’s background and mental state.

Iran refuses to reopen strait of Hormuz amid ongoing U.S. Naval blockade
Iran reaffirmed on Wednesday that it will not reopen the Strait of Hormuz while the United States maintains its naval blockade against Iranian ports and vessels, amid rising geopolitical tensions in the region.
Iranian Parliament Speaker Mohamad Baqer Qalibaf warned that reopening the crucial maritime route depends on Washington honoring the ceasefire agreement. According to Qalibaf, Iran considers the deal to be violated due to ongoing U.S. actions.
The Iranian official accused the United States of carrying out a “naval blockade and the hijacking of the global economy,” while also pointing to Israeli military operations in Lebanon as part of the broader conflict affecting the region.
Qalibaf stated that military and economic pressure would not force Iran to change its position. “The United States and Israel failed to achieve their goals through military aggression, and they will not succeed through intimidation. The only path forward is to recognize the rights of the Iranian nation,” he said.
His remarks come amid stalled negotiations between Iran and the United States following direct talks held on April 11 and 12 in Islamabad.
The discussions, led by U.S. Vice President JD Vance and Iranian representatives, have shown little progress in recent days, increasing uncertainty over whether dialogue between the two sides will resume.
U.S. President Donald Trump recently announced an extension of the ceasefire but decided to keep the naval blockade in place, a move Tehran considers incompatible with ongoing negotiations.
Meanwhile, Iran’s Islamic Revolutionary Guard Corps intensified operations in the area by seizing two vessels in the Strait of Hormuz, accusing them of operating without the required permits and escorting them into Iranian territory.
The Strait of Hormuz remains one of the world’s most critical oil trade routes, and any prolonged disruption could have significant consequences for global energy markets.

Maradona’s daughter accuses medical team of “horrible manipulation” in court
One of the daughters of Diego Maradona testified in court this Tuesday, breaking down in tears as she denounced what she described as “absolute and horrible manipulation” by her father’s medical team, during an emotional hearing in Argentina.
Gianinna Maradona stated that she and her siblings agreed to home hospitalization after doctors presented it as the best option following the neurosurgery Maradona underwent on November 3, 2020.
The football icon died on November 25 of that year, and the ongoing trial seeks to determine whether the conditions of his home care were appropriate.
According to Gianinna, what the family found at the residence where Maradona was recovering did not match what had been promised. She testified that there was no adequate medical equipment, constant monitoring, or even an ambulance available, despite assurances of continuous care.
“The manipulation was absolute and horrible,” she said during the hearing in San Isidro, near Buenos Aires.
She accused members of the medical team, including neurosurgeon Leopoldo Luque, psychiatrist Agustina Cosachov, and psychologist Carlos Díaz, of misleading the family.
“I trusted these people, and all they did was manipulate us and leave my son without a grandfather,” she added.
Later in her testimony, recalling that six years have passed since her father’s death, she became emotional and said she struggled deeply with grief in the aftermath.
