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.

Venezuela Earthquakes Spark Diplomatic Thaw With Former Critics

The devastating earthquakes that struck Venezuela have triggered an unprecedented diplomatic thaw between Caracas and several governments that had maintained strained relations with the country, raising hopes that the humanitarian response could pave the way for broader international engagement under the administration of U.S. President Donald Trump.

The United States, Chile, Argentina, El Salvador and Israel were among the first countries to announce humanitarian assistance, deploy search-and-rescue teams or establish direct contact with acting President Delcy Rodríguez to coordinate relief efforts in the hardest-hit areas.

Canada also joined the international response by announcing humanitarian aid while opening a domestic debate over the importance of maintaining diplomatic representation in countries such as Venezuela to better respond to emergencies and assist its citizens abroad.

The wave of international cooperation marks a sharp contrast to the diplomatic tensions that followed Venezuela’s disputed presidential election on July 28, 2024, in which Nicolás Maduro was declared the winner.

In the aftermath of that vote, the governments of Argentina, Chile, Costa Rica, Panama, Peru, the Dominican Republic and Uruguay publicly questioned the official election results, triggering one of the region’s most significant diplomatic crises in recent years.

The Venezuelan government responded by withdrawing its diplomatic personnel from several of those countries and demanding the departure of their representatives, further deepening the country’s international isolation.

The humanitarian emergency created by the twin earthquakes has now prompted renewed communication between Caracas and governments that had previously suspended or significantly reduced diplomatic engagement, underscoring how major natural disasters can temporarily reshape international relations despite longstanding political disagreements.

Venezuela Earthquake Death Toll Surpasses 1,700 as Search for Survivors Continues

Venezuelan authorities have raised the death toll from last week’s twin earthquakes to more than 1,700, as rescue teams continue searching for survivors in the country’s hardest-hit coastal region.

According to the latest official report released on Sunday, the powerful earthquakes, measuring magnitudes 7.2 and 7.5, have claimed at least 1,719 lives. National Assembly President Jorge Rodríguez also reported that 5,034 people were injured, while 15,866 have been displaced and another 22,619 are receiving medical care.

The United Nations has expressed growing concern over the scale of the disaster, estimating that as many as 68,000 people could still be missing.

La Guaira bears the brunt of the disaster

The coastal state of La Guaira has suffered the greatest loss of life and the most extensive damage. The Venezuelan government has declared the area a disaster zone and placed it under military control as emergency operations continue.

Five days after the earthquakes struck, search-and-rescue teams remain on the ground, supported by additional heavy equipment and international rescue crews. However, hopes of finding more survivors beneath the rubble continue to diminish with each passing day.

One of the most dramatic rescue operations unfolded Monday in Catia La Mar, where emergency teams from El Salvador, Mexico, and Venezuela worked together to reach a 21-year-old man who has remained trapped inside a collapsed building since the earthquakes struck.

The twin earthquakes hit Venezuela on June 24, with the epicenter located between San Felipe and Yumare in the country’s northern region. The first quake, measuring magnitude 7.2, struck at 6:04 p.m. local time. Just 39 seconds later, a second and stronger magnitude 7.5 earthquake occurred farther to the southeast. Combined, the seismic activity lasted nearly three minutes, causing widespread devastation across several regions of the country.

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.
