What do the remains found in the Chilean desert reveal? | Digital Trends Spanish

Located in the north of Chile, the Atacama Desert constitutes a good setting for the study of the fossil remains of the ancient inhabitants, this due to the lack of humidity in the area since it is the driest desert in the world. A new study of human remains from tombs between 3,000 and 1,400 years old reveals the violent struggle that could have occurred between the inhabitants of the area when agriculture began. According to research to be published in the Journal of Anthropological Archeology, the inhabitants of the desert attacked each other with maces, knives and hunting weapons, probably fighting for the scarcity of water and the availability of fertile land. The study found dozens of individuals with hair, meat and organs still intact, due to the aridity of the desert. Vivien Sta...

Two new species of dinosaurs discovered in China | Digital Trends Spanish

According to a study published in Nature Scientific Reports, a group of scientists discovered the fossils of three dinosaurs dating from the Early Cretaceous, between 130 and 120 million years ago. The fossils were found in the Turpan-Hami basin in northwestern China. The remains are believed to belong to two new species in a region where dinosaur fossils have never been unearthed before. The first specimen corresponds to a Silutitan sinensis, a new species of sauropod, a herbivore characterized by having a very extensive neck, a long tail, a large body and a small head, according to the study. Meanwhile, the second specimen, Hamititan xinjiangensis, is estimated to be more than 1.5 meters long and possessed characteristics similar to those of South American sauropods. Recreation. Chua...

Rare Ancient Creatures Keys to Explaining Evolution | Digital Trends Spanish

An article published in Nature explains in detail how some of the oldest and most unique species provide relevant information that allows the evolution of animals to be rewritten. One of the oldest known, the Yilinga spiciformis, evidence that some animal traits appeared five hundred million years ago. When it was found last year in China, they found tracks left by this creature, which has allowed us to know about the movement it made. In fact, many call this creature "the first walker." In the same region where it was discovered, the researchers found two parallel rows of dimples. They believe they were made by an animal 550 million years ago that might be capable of burrowing and possessed multiple pairs of appendages. This would make it one of the first known animals with legs...

The step by step of how was the mass extinction on Earth | Digital Trends Spanish

The Permian-Triassic period 252 million years ago ended abruptly with the extinction of millions of life forms. About three-quarters of all life on land and about 95 percent of life in the ocean disappeared within a few thousand years. The truth is that hethe latest analytical methods and detailed model calculations, the scientists at the Center GEOMAR Helmholtz Kiel Ocean Research, in cooperation with the Potsdam GFZ Helmholtz Center German Geosciences Research Center and international partners, have succeeded for the first time to provide a conclusive reconstruction of the geochemical processes that led to this unprecedented biotic crisis. The study has been published this October 19 in the journal Nature Geoscience. The investigation details step by step how the destruction was...

Drastic environmental change recorded in tree fossil in Peru | Digital Trends Spanish

Researchers at the Smithsonian Tropical Research Institute (STRI) were surprised by the finding of a huge fossil tree buried in an arid plateau in the Peruvian Andes, Europa Press reported. In a study published in the journal Science Advances, scientists point out that this and other high-altitude fossils are dramatic reminders that the environment has changed dramatically over the past 10 million years, but not in the way that past climate models suggest. By analyzing the tree, along with fossils of wood, leaves and pollen, they discovered that, when the plants were alive, "the ecosystem was more humid than predicted by old climate models," says Camila Martínez, a STRI fellow, who was part of Of the investigation. For his part, the head of the expedition, scientist Car...

Unpublished turtle that lived 200 million years ago found | Digital Trends Spanish

Fossils of an unpublished species of tortoise that inhabited Argentina about 205 million years ago, which lived with different kinds of dinosaurs, were found by paleontologists from the National University of San Juan (UNSJ), reported Sputnik. The researchers found four specimens of the turtle, baptized as Waluchelys Cavitesta, in the town of Balde de Leyes, in the Cuyo region, the same place where they previously discovered remains of the huge dinosaur Ingentia Prima. The specimens of this turtle were found in different explorations carried out between 2015 and 2018. "This new species is among the oldest known turtles and its study provided us with data on how its shell originated," said Juliana Sterli, researcher at the Egidio Feruglio Museum (MEF) and the National Co...
