Dinosaur tail found in Chile stuns scientists

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.

Ecuador’s Noboa vows to continue “war” on criminal groups

Ecuador’s President Daniel Noboa said on Sunday that his government will continue the “war” against criminal organizations and warned that he will not yield to criminal gangs operating in the South American country.

During his state-of-the-nation address before the National Assembly, Noboa stated that criminal structures “will tire first” before his administration abandons its fight against violence and drug trafficking.

The president reaffirmed his hardline security strategy amid ongoing concerns over organized crime and drug-related violence in Ecuador.

Iran says agreement with U.S. to end Middle East conflict is in final stages

Iran’s Foreign Ministry spokesperson, Esmail Baqai, said Saturday that Tehran and the United States were in the “finalization phase” of a memorandum of understanding aimed at ending the conflict in the Middle East.

Speaking to Iranian state television Irib, Baqai explained that Iran had initially sought to draft a memorandum consisting of 14 clauses as part of the negotiations.

“We are currently in the phase of finalizing these memorandums of understanding,” he stated.

Shortly before Baqai’s remarks became public, U.S. Secretary of State Marco Rubio said there was “a possibility” that Iran could agree to a deal to end the conflict as early as Saturday.

“There is a possibility that later today, tomorrow, or within the next couple of days, we may have something to announce,” Rubio told reporters in New Delhi, adding that he hoped for “good news.”

Despite acknowledging progress in the negotiations, the top U.S. diplomat warned that President Donald Trump could still decide to resume military strikes against Iran if talks fail to produce a final agreement.

WHO Warns Ebola Outbreak Is Spreading Rapidly in DR Congo

The World Health Organization on Friday raised the risk level of the Ebola outbreak in the Democratic Republic of the Congo from “high” to “very high,” the highest alert category used by the organization.

WHO Director-General Tedros Adhanom Ghebreyesus said the outbreak is spreading rapidly across the country, particularly in the eastern provinces of North Kivu and South Kivu.

“The Ebola outbreak in the Democratic Republic of the Congo is spreading rapidly,” Tedros stated during a press conference.

He explained that the WHO had previously classified the risk as high at both the national and regional levels, while maintaining a low risk assessment globally.

“We are now revising our risk assessment to classify it as very high at the national level, high at the regional level, and low at the global level,” he added.

A WHO spokesperson told AFP that “very high” represents the organization’s highest risk category.

The outbreak has expanded across North Kivu and South Kivu, regions divided by the frontline between Congolese government forces and the armed group M23, which is reportedly backed by Rwanda and has seized large areas of territory since 2021.
