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.

Japan reopens Kashiwazaki-Kariwa Plant despite public concerns

La centrale nucléaire japonaise de Kashiwazaki-Kariwa, la plus grande au monde, a repris ses activités mercredi pour la première fois depuis la catastrophe de Fukushima en 2011, malgré les inquiétudes persistantes d’une partie de la population.

La remise en service a eu lieu à 19h02 heure locale (10h02 GMT), a indiqué à l’AFP Tatsuya Matoba, porte-parole de la compagnie Tokyo Electric Power (Tepco).

Le gouverneur de la préfecture de Niigata, où se situe la centrale, avait donné son feu vert à la reprise le mois dernier, en dépit d’une opinion publique divisée. Selon une enquête menée en septembre par la préfecture elle-même, 60 % des habitants se déclaraient opposés au redémarrage, contre 37 % favorables.

Mardi, plusieurs dizaines de manifestants ont bravé le froid et la neige pour protester près de l’entrée du site, sur les rives de la mer du Japon.

« L’électricité de Tokyo est produite à Kashiwazaki. Pourquoi seuls les habitants d’ici devraient-ils être exposés au danger ? Cela n’a aucun sens », a déclaré à l’AFP Yumiko Abe, une riveraine de 73 ans.

La centrale de Kashiwazaki-Kariwa avait été mise à l’arrêt lorsque le Japon a fermé l’ensemble de ses réacteurs nucléaires à la suite du triple désastre de mars 2011 — un séisme, un tsunami et un accident nucléaire — survenu à Fukushima.

Markets rise as Trump halts Europe tariffs and floats Greenland agreement framework

U.S. President Donald Trump on Wednesday lifted his threat to impose new tariffs on several European countries and said he had outlined the framework of a future agreement on Greenland during a meeting in Davos with NATO Secretary General Mark Rutte.

“Based on this understanding, I will not impose the tariffs that were scheduled to take effect on February 1,” Trump wrote on his social media platform Truth Social, without providing details about the proposed “framework.”

The announcement boosted financial markets. Wall Street, which had been trading slightly higher, extended its gains following Trump’s message, while the U.S. dollar strengthened against the euro.

Trump has repeatedly insisted that Greenland, rich in mineral resources, is ‘vital’ to the security of the United States and NATO, particularly as Arctic ice melts and global powers compete for strategic advantage in the region amid rising tensions with China and Russia.

Last week, the U.S. president threatened to impose tariffs of up to 25% on eight European countries for supporting Denmark and sending a military exploratory mission to Greenland. All of the targeted countries are NATO members, including the United Kingdom, Germany, and France, Europe’s largest economies.

Trump said on Wednesday that additional discussions are underway regarding the “Golden Dome” missile defense system, specifically in connection with Greenland.

He assigned Vice President JD Vance, Secretary of State Marco Rubio, and special envoy Steve Witkoff to lead the negotiations.

Hours before his post, Trump ruled out the use of force to seize Greenland for the first time, but demanded “immediate negotiations” for its acquisition, reiterating his view that only the United States can guarantee the security of the Arctic island.

Venezuela’s interim president predicts 37% increase in revenues for 2026

Venezuela’s interim president, Delcy Rodríguez, said Wednesday that the country’s revenues are expected to increase by about 37% in 2026, in a statement made during a session of the Federal Government Council at the Miraflores Presidential Palace in Caracas.

Rodríguez said the projected rise in foreign currency income comes as agreements on Venezuelan oil sales with the United States are being implemented, including deals in which Washington will trade Venezuelan crude and manage the proceeds before transferring funds to Caracas.

“This year, revenues expressed in foreign currency will increase by 37%,” Rodríguez declared, according to EFE. She noted that the increase will also benefit regional governments and local authorities. “You will have more resources for your management, which I know you need,” she added.

Rodríguez said the distribution formula for revenues will remain the same as in 2025: 53% for communes, 29% for state governments, 15% for municipalities, and 3% for institutional strengthening. She also said the government would intervene to “correct imbalances” in how funds are allocated, particularly among some municipal and regional authorities.

The announcement follows reporting that Venezuela received at least $300 million from oil revenues tied to a U.S.–Venezuela deal that could involve up to 50 million barrels of crude. Washington officials have said the interim government met U.S. requirements under the agreement.
