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.

Nine People Killed in Two Armed Attacks in Manabí, Ecuador
At least nine people were killed Monday in two nearly simultaneous armed attacks in the province of Manabí, located on Ecuador’s Pacific coast, one of the areas hardest hit by violence in the country, according to the National Police.
The first attack left seven people dead and took place in Camarones, a rural area of the Jama canton. The second occurred in the sector known as La Y, in the seaside town of Canoa, part of the San Vicente canton, where two people were killed.
According to preliminary reports, both incidents occurred early Monday morning when armed men intercepted the victims. Authorities said the motives behind the attacks remain under investigation.
The assault in Camarones happened around 1:15 a.m. local time, when a group of armed individuals stormed a ranch in the area. The victims have not yet been officially identified.
About 15 minutes later, in Canoa, two men traveling in a motorized taxi were intercepted by armed suspects riding motorcycles and shot. One of the victims was identified as a 28-year-old passenger, while the identity of the driver has not yet been confirmed.
The attacks occurred just days after another multiple homicide on February 12 at a ranch in San Juan de las Cucarachas, a rural area of the Santa Ana canton in Manabí, which left six people dead.
Manabí has been experiencing escalating insecurity linked to disputes among organized crime groups, including drug trafficking networks and territorial control conflicts. In response, the government has maintained a state of emergency in the province since August to address the surge in violence attributed to these criminal organizations.

Over 40 Million Affected by Major Snowstorm in Northeastern U.S.
More than 40 million people across the northeastern United States are facing a new major snowstorm this Monday, including residents of New York City, where local authorities have shut down roads to traffic.
The storm triggered widespread flight cancellations early in the morning and caused power outages affecting thousands of homes and businesses throughout the region.
New York City Mayor Zohran Mamdani banned non-essential vehicle travel at least until noon and ordered the closure of public schools as a precautionary measure. Authorities in neighboring states, including New Jersey and Rhode Island, imposed similar restrictions to ensure public safety.
This marks the second major winter storm to hit the East Coast in less than a month, leading to growing frustration among residents.
“I’m fed up. I don’t want to see another snowflake,” said Vincent Greer, a resident of Wildwood, New Jersey, as he shoveled accumulated snow from in front of his building.
Officials continue to urge residents to remain indoors, avoid unnecessary travel, and monitor local advisories as crews work to clear roads and restore power.

Ninth Victim Recovered After Deadliest U.S. Avalanche in Decades
Rescue teams in California on Saturday recovered the body of the ninth and final victim of a deadly avalanche in the Sierra Nevada mountains, according to the local sheriff’s office.
The avalanche struck a group of 11 skiers and four guides on Tuesday as they were returning from a three-day backcountry trip near Castle Peak, a 2,777-meter (9,111-foot) mountain and popular tourist destination on the U.S. West Coast.
Six people were rescued alive on Tuesday. Authorities said the incident marks the deadliest avalanche in the United States since 1981.
“All nine individuals who lost their lives in the February 17 Castle Peak avalanche have been safely recovered from the mountain,” the Nevada County Sheriff’s Office said in a statement.
“There are no words that can truly capture the magnitude of this loss, and our hearts grieve alongside the families affected by this catastrophic event,” Sheriff Shannan Moon said.
Officials had warned on Thursday that search operations would likely continue through the weekend due to severe weather conditions in the area.
Survivors were able to call for help shortly after the avalanche occurred. However, near-zero visibility and the risk of additional snow slides prevented rescue teams from reaching them for several hours.
