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.

Three U.S. Executions Set for Same Day as Trump Pushes to Expand Death Penalty

The death penalty has been abolished in 23 of the 50 U.S. states, while three others —California, Oregon and Pennsylvania— currently have moratoriums in place.

The United States is set to carry out three executions on the same day, a rare occurrence that has not happened since 2010, according to the nonprofit Death Penalty Information Center.

President Donald Trump has sought to expand the use of capital punishment for what he describes as “the most heinous crimes.” In April, the Department of Justice proposed expanding execution methods to include firing squads, lethal gas and electrocution.

Tennessee is scheduled to execute Anthony Darrell Dugard Hines, 66, on Thursday. He was sentenced to death for the 1985 murder of a woman, according to local media.

In Oklahoma, Carlos Cuesta-Rodríguez, 70, is scheduled to be executed for a 2003 murder.

Meanwhile, Alabama plans to execute Jeremy Williams, 42, who was sentenced to death for the rape and murder of a five-year-old girl.

The United States carried out 47 executions in 2025, the highest number since 2009, when 52 executions were recorded.

Florida conducted the largest number of executions last year, with 19, followed by Alabama, South Carolina and Texas, with five each.

Of the executions carried out in 2025, 39 were conducted by lethal injection. Three were carried out by firing squad and five through nitrogen hypoxia, a method that involves forcing nitrogen gas into a face mask, depriving the prisoner of oxygen.

The United Nations has condemned nitrogen gas as a cruel and inhumane method of capital punishment.

Colombia Earthquake Death Toll Reaches 265 as Rescue Teams Race Against Time

The 7.4-magnitude earthquake that struck Colombia on Monday, the strongest to hit the country this century, has so far left 265 people dead and around 3,500 injured.

In Cali, Pereira and other cities in western Colombia, rescue teams are working around the clock as they search for survivors. The first 72 hours following the earthquake will be reached at 7:34 a.m. local time (12:34 GMT), a critical window for rescue efforts as the chances of finding survivors generally decline significantly after that point.

Among those anxiously awaiting news is Valeria Cardona, a 26-year-old student searching for two of her cousins in Cali.

“We have some suspicions about their location, but there are no signs of life,” she said. “Hope is the last thing you lose, but we are anxious about receiving news we don’t want to hear.”

A team of members from the Topos Aztecas, the renowned Mexican volunteer rescue group, has also arrived in Cali to join the search. The rescuers had been working in neighboring Venezuela, where a double earthquake on June 24 left more than 6,000 people dead.

“We all came from Venezuela, from La Guaira. The 41 days we spent working there made us stronger because we overcame hunger, pain and sleepless nights,” said Héctor Méndez, 80, president of Topos Aztecas.

Méndez encouraged those affected by the disaster not to lose hope and emphasized the commitment required from rescue teams during an emergency.

“Do not feel like victims. This is not an office or workshop schedule. This is real life, where the best part of the human spirit emerges. These are things of nature that happen,” he said.

German Authorities Investigate More Than 100 New Cases Against Convicted Nurse

German authorities announced Monday that they are investigating more than 100 additional cases involving a nurse who was sentenced to life in prison in November for the murder of 10 patients.

The man, who was 44 at the time of his conviction, worked in palliative care at a hospital in Würselen, near Aachen. He was also found guilty of 27 attempted murders.

Aachen prosecutors are now examining 121 new cases, a spokesperson for the office said.

Prosecutors leading the investigation are preparing a new indictment that could be filed next year. Nearly 40 bodies have so far been exhumed as part of the investigation, which covers alleged incidents dating back to September 2022.

Meanwhile, prosecutors in the city of Cologne are investigating 18 additional cases. According to a spokesperson, the oldest case dates back to 2010.

Before working at the Würselen hospital, the nurse is believed to have worked at a clinic in eastern Cologne, according to local media reports.

At the time of his November conviction, the court ruled that the severity of his crimes was particularly serious, a finding that would make it difficult for him to obtain early release after 15 years in prison.

Between December 2023 and May 2024, the nurse administered overdoses of sedatives or painkillers to terminally ill patients, most of them elderly, according to the indictment in the original case.

His alleged motive was to sedate patients who required care so that he could minimize his workload during night shifts, prosecutors said.

According to the indictment, the nurse worked «without enthusiasm» and «without motivation». When faced with patients requiring extensive care, he allegedly became «irritated» and showed a lack of empathy.

The case has revived painful memories in Germany of Niels Högel, a former nurse and serial killer who was sentenced to life imprisonment in June 2019 for the murders of at least 85 patients.
