Santiago: The remains of a letter-like creature that lived during the dinosaur era have been found in Chile’s Patagonia, adding further evidence that mammals roamed that part of South America long before they were thought to exist.
Part of the five-toothed creature’s organic jaws was found near the famous Torres del Paine National Park.
Christened Orretherium zen, meaning “fifth tooth of an animal,” is considered in a group of Greeks and the local indigenous language; this animal lived at the end of the Mesozoic era, during the Upper Cretaceous period, 72 to 72 million years ago, and A vegetarian
Before its discovery, and last year in the same area, the teeth of a mouse-like creature, Magellanodon bikshanke, were found in the southern part of the United States, where normal mammals lived only 38 to 46 million years ago, the team said.
The findings are important to complete the evolutionary puzzle of Gondwanatheria, a long-disappearing group of simple mammals associated with dinosaurs, said Sergio Soto, a Chilean University scientist.
“These and other discoveries that we are going to report in the future show that there is a lot of potential for archeology in the southern part of Chile,” Soto said.
“We are looking for things we didn’t expect, and they will help us answer many of the questions we have long had about dinosaurs, mammals, and other groups.”
The findings were published in the journal Scientific Reports by experts from the University of Chile working with researchers from Argentina’s Natural History and La Plata Museums and the Chile Antarctic Institute.
Scientists believe that the auditorium zen worked closely with Maglanodon Beksakshenke, believed to be an evolutionary step between platypus or marsupials and dinosaurs, such as the long-necked titanosaur.
