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.

China calls for dialogue amid rising Iran-Israel conflict
The Chinese government emphasized on Monday the importance of “creating the conditions to return to the proper path of dialogue” between Iran and Israel, which have exchanged attacks in recent days resulting in more than 20 Israeli and over 220 Iranian deaths.
Chinese Foreign Ministry spokesperson Guo Jiakun expressed deep concern at a press conference over the Israeli attacks on Iran and the “sudden escalation” of the military conflict.
Guo called on all parties to “take immediate measures to ease tensions and prevent the region from descending into further turmoil,” stating that “force cannot bring lasting peace.”
“If the conflict between Israel and Iran continues to intensify or even expand, the countries of the Middle East will be the first to suffer the consequences,” he added, while noting that China “will continue to maintain communication with the relevant parties, promoting peace and dialogue.”
Chinese Foreign Minister Wang Yi spoke last Saturday with his Iranian and Israeli counterparts to condemn the Israeli airstrike on Iranian territory, which he described as a “violation of international law” with the potential to trigger “disastrous” consequences.
In both calls, Wang reiterated China’s rejection of the use of force, defended diplomacy as the only solution to the Iranian nuclear dispute, and offered China’s mediation to prevent further destabilization in the Middle East.

Suspect arrested in killing of Minnesota legislator and husband, governor Says
Minnesota Governor Tim Walz announced on Sunday the arrest of Vance Luther Boelter, 57, the main suspect in the killing of Democratic legislator Melissa Hortman and her husband in a Brooklyn Park suburb on Friday night.
Boelter, who also reportedly shot State Senator John Hoffman and his wife early Saturday morning, was apprehended in Sibley County following an intensive manhunt involving hundreds of law enforcement officers.
In a public statement, Governor Walz condemned Boelter’s “unthinkable actions,” which resulted in the death of a woman who “shaped the core of who we are as a state.”
“We cannot become numb to this. We are a deeply divided nation,” Walz said in a statement posted on his X account.
“We move forward not with hatred or violence, but with humility, grace, and civility,” he added.
Expressing solidarity with the victims’ families, Walz said the entire state of Minnesota is in mourning. He also thanked law enforcement for their bravery and professionalism: “They have saved lives,” he emphasized.
“As we heal, we will not let fear win,” Walz concluded. “We must honor Melissa by moving forward with understanding, service, and above all, humanity.”
Throughout Sunday, police and sheriff units searched a rural area in Minnesota for Vance Luther Boelter, a security company director and preacher who, according to Governor Walz, acted out of politically motivated violence.

40,000 tourists stranded in Israel amid airspace shutdown over Iran conflict
Approximately 40,000 tourists are stranded in Israel following the closure of the country’s airspace amid escalating hostilities with Iran, the Israeli Ministry of Tourism reported on Monday.
The ministry has set up a virtual office to provide information via email (virtual@goisrael.gov.il) and phone (+972-53-583-5808), as well as a Facebook page called Israel Virtual Tourist Office.
Israeli Tourism Minister Haim Katz is in contact with hotels and accommodations across the country to offer support to tourists in need, the ministry added.
Many stranded travelers are considering crossing overland into Jordan or Egypt to seek flights from those countries. The Israel Airports Authority reminded the public that land border crossings remain open.
Three German tourists stranded in Jerusalem told EFE today that they have not received any assistance from their country’s embassy in Israel, and their primary option currently is to cross into Jordan to catch a flight from there.
Since early Friday morning, Israel launched operations against Iran, targeting military personnel and infrastructure, including energy and nuclear facilities, as well as numerous residential areas in Tehran.
In response, Iran has fired hundreds of ballistic missiles at Israel, some of which have struck various locations across the country, leaving at least 24 dead so far, according to Israeli authorities.
Iranian health officials report at least 224 deaths, mostly civilians, including at least 17 senior military officials—nine from the Revolutionary Guard—and more than a dozen nuclear scientists.
The Israeli military has warned that many more “targets” remain, while Iran’s Revolutionary Guard declared on Monday that it will continue missile attacks against Israel until its “destruction.”
