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.

Brazil’s Bolsonaro Returns to Prison After Supreme Court Denies House Arrest
Former Brazilian president Jair Bolsonaro left a hospital in Brasília on Thursday after spending more than a week admitted and returned to prison, after the Supreme Court denied his request for house arrest, an AFP journalist reported.
Bolsonaro, 70, departed the DF Star Hospital under a police motorcycle escort and was transferred back to a small room at a police facility, where he is serving a 27-year sentence for attempting to stage a coup to remain in power after losing the 2022 election to Luiz Inácio Lula da Silva.
The nine-day hospitalization marked Bolsonaro’s first time outside custody since his imprisonment. His legal team had requested house arrest on health grounds following surgery last week for an inguinal hernia, arguing there was a “concrete risk of sudden deterioration” in his condition. He was also treated for recurring bouts of hiccups.
However, Supreme Court Justice Alexandre de Moraes rejected the request, stating that, contrary to the defense’s claims, there had been no worsening of Bolsonaro’s health condition. The former right-wing leader was admitted to the hospital on December 24 and underwent surgery the following day.
