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.

Pilot killed and two Pennsylvania state troopers injured in mid-air collision

A pilot was killed and two Pennsylvania state police officers were injured when a Cessna 150 airplane collided with the helicopter they were traveling in during a routine training exercise at a regional airport in the state.

Pennsylvania Governor Josh Shapiro identified the officers as Corporal Bryce Corman and Trooper Jason Mills, members of the Pennsylvania State Police aviation unit. Both are expected to recover from their injuries, according to ABC.

The county coroner’s office identified the pilot as 57-year-old Paul Sokoloski.

George Bivens, acting commissioner of the Pennsylvania State Police, said the collision occurred at around 6:50 p.m. Wednesday. The helicopter was flying several feet above a grassy area near a runway at Carlisle Regional Airport when the small plane approached from behind.

According to investigators, the Cessna suddenly veered to the right moments before the collision, striking the helicopter’s tail rotor before also hitting its main rotor.

The airplane crashed a short distance away and broke into several pieces, while the helicopter lost its tail and other components before crashing on its side.

Police said Corporal Corman opened a window and helped Trooper Mills escape from the helicopter because they feared the aircraft could catch fire.

The Federal Aviation Administration and the National Transportation Safety Board are investigating the circumstances surrounding the crash.

Argentina’s Milei Links Low Birth Rates to Abortion and Feminism

Argentine President Javier Milei on Thursday blamed feminism and the legalization of abortion for the country’s declining birth rate, arguing that the demographic trend is creating economic and pension-system challenges.

“We are paying a very high price for the madness of the green scarves,” Milei said during a speech at the Council of the Americas in Buenos Aires, referring to the symbol associated with the feminist movement and the campaign for legal abortion in Argentina.

According to Milei, Argentina is failing to reach the population growth and birth rates needed to maintain demographic replacement.

He also linked the decline in births to future challenges for the country’s pension system and workforce.

“That passion for killing children in the mother’s womb is costing us in terms of growth and pensions. It is also costing us in terms of human capital,” the president said.

Milei has consistently opposed abortion, which has been legal in Argentina since 2020. The law was considered a major victory for the feminist movement across Latin America at the time of its approval.

In February 2024, lawmakers from Milei’s La Libertad Avanza (LLA) party introduced a bill seeking to repeal voluntary abortion legislation.

Under Argentina’s current law, abortion is legal, safe and free of charge up to the 14th week of pregnancy. After that period, it is permitted when the pregnancy poses a risk to the woman’s life or health, or when it resulted from rape.

Milei has repeatedly criticized abortion

The Argentine president has also criticized abortion and feminism in international forums. During his speech at the World Economic Forum in Davos in January 2024, he attacked the feminist movement and denounced what he described as the “bloody agenda of abortion.”

His latest comments come amid growing concerns over Argentina’s demographic outlook and the potential long-term effects of declining birth rates on economic growth, the labor force and social security.

Virginia Police Arrest Salvadoran Man in Great Falls Woman’s Killing

Alexis Antonio Cedillos-Campos, 19, identified by federal officials as an undocumented immigrant from El Salvador, was arrested in connection with the death of Carmen Lizet Puch, 42, who was found dead Monday, the Fairfax County Police Department said.

Authorities said Cedillos-Campos and Puch were coworkers and were also involved in an “intimate relationship.”

“Our victim suffered numerous stab wounds in a truly brutal and indescribable manner,” Police Chief Kevin Davis said during a news conference Wednesday.

Investigators said surveillance video showed Cedillos-Campos at the restaurant where he and Puch worked, allegedly taking a fixed-blade knife, a pair of black latex gloves and a bottle of water before leaving.

“He left with the intent to harm and kill the victim,” Davis said.

Cedillos-Campos was arrested Wednesday morning in Maryland and confessed to the killing, according to Davis. He is awaiting extradition to Virginia. Authorities have not said whether he has an attorney representing him.

The Department of Homeland Security said Cedillos-Campos had previously been arrested by U.S. Customs and Border Protection in 2024 after allegedly crossing the U.S.-Mexico border illegally near El Paso, Texas.
