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.

Looting Spreads in Venezuela’s Hardest-Hit Areas After Deadly Earthquakes

Not even the wires were left behind at a small grocery store. Before the ground had even stopped shaking, looting and theft began in the areas hardest hit by the double earthquake that struck Venezuela.

Reports of robberies have multiplied in the coastal state of La Guaira, located near Caracas and now transformed into a landscape of collapsed buildings and debris.

Videos circulating on social media show groups of people removing boxes of household appliances from a damaged store. Other images show similar boxes being carried on top of vehicles and motorcycles.

Social media platforms have also been filled with accusations against police officers and military personnel who allegedly stole from homes and even from victims who died during the disaster.

A branch of a major pharmacy chain was looted, along with supermarkets and other businesses. Some residents have described the situation as “disaster tourism,” while others say the looting reflects hunger and desperation among people who lost everything in a country already facing a prolonged economic crisis.

“Is it fair that our own people turn against our own people?” said María Esther Bernal, 71, who rented commercial spaces to Chinese merchants, all of which were looted. “They left nothing behind, not even the wallpaper. They even took the cables,” she said.

“Next door, a man died. He was Chinese. People walked over his body while they looted the place. It was a supermarket,” she added.

An AFP journalist witnessed looting in La Guaira since Thursday, following the earthquakes.

Jenifer Mayora, 34, defended some of the actions, saying that “the things people took were because the owners of the stores allowed us to take them.”

However, she criticized the limited response from authorities. “I have been waiting for a mattress so my children can sleep,” she said.

Residents have expressed anger over what they describe as a slow and insufficient response from authorities after the double earthquake, which has left around 1,450 people dead and tens of thousands missing.

Communities are demanding not only faster rescue operations in La Guaira, but also stronger security measures and urgent assistance with food, water, and medicine.

UN warns Venezuela earthquakes could affect up to 6.76 million people

Up to 6.76 million people could be affected by the devastating earthquakes that struck Venezuela on June 24, according to an assessment released by the International Organization for Migration (IOM), a United Nations agency.

The organization said the projections are based on available population data and damage assessments, and include up to two million people living in Caracas, the country’s capital.

The estimates highlight the potentially massive humanitarian impact of the disaster, the IOM warned.

Entire buildings collapsed in La Guaira, a coastal area north of Caracas, following the powerful twin earthquakes that reached magnitudes of 7.2 and 7.5 on Wednesday.

The national death toll has risen to 920, while rescue teams continue searching for people trapped beneath the rubble in coastal regions and other affected areas.

UN humanitarian chief Tom Fletcher told AFP on Friday that more than 50,000 people were reported missing.

The IOM also revealed that it worked with Microsoft’s artificial intelligence laboratory on an initial satellite mapping analysis, which showed that 31.5% of buildings in the town of Catia La Mar had suffered damage.

Authorities and international rescue teams continue operations as Venezuela faces one of its largest humanitarian emergencies in recent years.

United Nations Coordinates Relief Efforts as Venezuela Death Toll Rises After Twin Quakes

United Nations Secretary-General António Guterres on Thursday expressed his condolences to the people of Venezuela following the two devastating earthquakes that struck the country and highlighted the ongoing coordination between UN humanitarian teams and interim President Delcy Rodríguez.

Speaking during the UN’s daily press briefing, spokesperson Stéphane Dujarric said Guterres was deeply saddened by the loss of life and widespread destruction caused by the disaster.

“The Secretary-General is deeply distressed by the loss of life and the widespread devastation caused by the earthquakes that struck Venezuela yesterday. He extends his heartfelt condolences to the families of the victims and wishes a speedy recovery to those injured,” Dujarric stated.

Venezuela was struck on Wednesday by two powerful earthquakes measuring 7.2 and 7.5 in magnitude. According to official figures, the disaster has left at least 164 people dead and 971 others injured.

Dujarric noted that preliminary reports indicate significant damage across several states, including the capital, Caracas. Numerous casualties have been reported, while other individuals remain trapped beneath collapsed structures or are still missing.

“Critical infrastructure has been damaged and essential services have been disrupted,” the spokesperson said.

The United Nations confirmed that its humanitarian team remains in close contact with interim President Delcy Rodríguez and other relevant authorities as emergency operations continue.

To support relief efforts, the UN has established a coordination center in Caracas and is assisting local authorities to ensure that humanitarian aid reaches affected communities as quickly and efficiently as possible.

Guterres also welcomed the expressions of solidarity and offers of assistance from countries around the world that responded following news of the disaster, underscoring the importance of international cooperation in addressing the humanitarian emergency.
