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.

Erin brings strong winds and storm surge despite weakening offshore

Hurricane Erin weakened to a Category 2 storm on Tuesday but continues to pose a threat to parts of the U.S. East Coast with potentially dangerous flooding, according to meteorologists.

Although the hurricane’s eye is expected to remain offshore, experts are concerned about Erin’s size, as strong winds extend hundreds of kilometers beyond the storm’s center.

In its 18:00 GMT bulletin, the U.S. National Hurricane Center (NHC) lifted tropical storm warnings for the Bahamasand Turks and Caicos Islands, but kept them in effect for parts of North Carolina.

Erin was located several hundred kilometers southeast of North Carolina and was moving northwestward.

“This means there is a risk of potentially life-threatening flooding of 60 to 120 centimeters above ground level,” said NHC Director Michael Brennan.

He also warned of the possibility of destructive waves, combined with storm surge, that could cause severe damage to beaches and coastal areas, making roads impassable.

Three U.S. Warships deploy near Venezuela to combat drug trafficking

Three U.S. naval vessels are moving toward the coasts of Venezuela, according to international media reports on Tuesday, after White House spokesperson Karoline Leavitt confirmed that President Donald Trump is ready to combat and curb international drug trafficking.

Reports indicate that the ships will reach Venezuelan waters within the next 36 hours as part of a recent U.S. deployment aimed at countering international narcotics operations.

The announcement coincides with Leavitt’s statement that Trump is prepared to “use the full extent of his power” to halt drug flows into the United States. The naval deployment involves approximately 4,000 military personnel.

“The President has been clear and consistent. He is ready to use every element of U.S. power to prevent drugs from flooding our country and to bring those responsible to justice. The Maduro regime is not the legitimate government of Venezuela—it is a narco-terror cartel,” the spokesperson said during a press conference.

Cuban authorities free salvadoran convicted in 1997 hotel bombing

Salvadoran national Otto René Rodríguez Llerena was released after serving a 30-year prison sentence for his involvement in a terrorist attack at a hotel in Cuba in 1997, the Cuban Ministry of Foreign Affairs reported.

During his trial, Rodríguez Llerena admitted to placing an explosive device at the Meliá Cohiba Hotel under the orders of anti-Castro exile leaders. He was arrested the following year when he returned to Havana with another load of explosives that failed to detonate.

“The Cuban government reiterates its commitment to combating terrorism, respecting human rights, and the need for the international community to hold accountable those who promote such acts,” the statement read.

He was released on August 15 and is the second Salvadoran to complete his sentence. In December of last year, another Salvadoran, Ernesto Cruz León, was released after planting bombs at tourist centers, one of which killed an Italian tourist identified as Fabio Di Celmo.

A third Salvadoran, Francisco Chávez Abarca, also received a 30-year sentence from Cuban courts in 2010 after being extradited from Venezuela through Interpol for actions against Cuba.

Rodríguez Llerena had requested conditional release in 2016, arguing that his actions had not caused any direct fatalities, but no further information was released about his situation until now.
