They find an unknown function of the tail of dinosaurs | Digital Trends Spanish

New research carried out by Harvard University has revealed an unknown function of the dinosaurs' tail. Researchers have now discovered that the tail helped them run more stably and efficiently. This, after previous research focused especially on the legs of these animals. In fact, dinosaurs' tails were previously thought to be passive structures that only served to help with balance. Now, aided by a simulation method, Peter Bishop, lead author of the study, and his team wanted to take a deeper look at the biomechanics of bipedal dinosaurs and the function of their tails. The model used was applied in a digital design made from computed tomography of the fossils of a Coelophysis bauri, a species of dinosaur that lived during the Triassic period, more than 200 million years ago. In the ...

A reptile survived the meteorite that killed the dinosaurs | Digital Trends Spanish

The fall of the meteorite that extinguished the dinosaurs and other large vertebrates had a survivor that is still present today. A new study has revealed that snakes already existed more than 66 million years ago. The study published in Nature by a group of scientists explains that snakes are one of the few animals that survived the mass extinction, which took 76 percent of the existing species. The cataclysm created new spaces for the snakes, which had a free way to expand to other places and continents. Not only that, but that expansion was also reflected in the appearance of new subspecies or lineages, beyond the six that survived the event. This is what scientists call creative destruction, a concept that can be read contradictory but that postulates that the destruction of one ...

This dinosaur was the great predator before the T-Rex | Digital Trends Spanish

Until now, it is accepted that the Tyrannosaurus Rex has been the king of predators among the dinosaurs. But before the T-Rex there was another great dinosaur, the predecessor on the throne of the great predators and that was recently discovered by researchers at the University of Tsukuba: the Ulughbegsaurus uzbekistanensis. This specimen lived 90 million years ago and the analysis of a fossil found in Uzbekistan - hence the name of the animal - reveals that it had a mass of more than 1 ton, while measuring between 7.5 and 8 meters long. The Ulughbegsaurus belongs to the group of the carcharodontosauria, which were the largest predators existing before the emergence of tyrannosaurs. This group of dinosaurs also shared territory with other smaller tyrannosaurs, which at that time were ...

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...

Asteroid that killed dinosaurs left crater that housed life | Digital Trends Spanish

In May 2020, a study published by the journal Nature revealed the trajectory angle of the meteorite that struck our planet 66 million years ago in the Yucatan Peninsula. A gigantic impact that left a 180 square kilometer crater and produced an underground magma chamber. By the way, I end the life of the dinosaurs. An investigation published this Monday in the magazine Astrobiology ensures that the underground chamber, which persisted for millions of years, sheltered a relevant microbial ecosystem, reported Gizmodo. According to David Kring, lead author of the study and a geologist at the Lunar and Planetary Institute (LPI) in the United States, the hydrothermal system that survived in the crater, called Chicxulub, could help explain the beginning of life on Earth. Artistic recrea...

Pterosaurs improved their flight for millions of years | Digital Trends Spanish

Pterodactyls and other winged reptiles that lived during the time of the dinosaurs steadily improved their ability to fly, allowing them to dominate the skies for approximately 150 million years. The study of the universities of Reading, Lincoln and Bristol, published in the journal Nature, is considered the most detailed yet on how animals evolve to better adapt to their environments. Pterosaurs, the first flying vertebrates on Earth, evolved from land animals. They first emerged as fliers in the Early Triassic period, about 245 million years ago, but became extinct 66 million years ago along with the dinosaurs. "Pterosaurs were a diverse group of winged lizards, some the size of sparrows and others with the wingspan of a small airplane (...) Their diet consisted mainly of other ...

T-Rex skeleton auction would break all records | Digital Trends Spanish

Okay, we admit it: the Tyrannosaurus rex It is one of our favorite dinosaurs, especially for those of us who grew up in the nineties and the cinema and literature were in charge of growing this admiration for the giant with the short arms. This fanaticism can reach unsuspected instances, as it can now happen with the auction of the most complete skeleton of T-rex, which can reach a record sale price. This is Stan, named after Stan Sacrison, a paleontologist who discovered him in 1987, on private land near Buffalo, South Dakota. The skeleton dates back to the Upper Cretaceous, between 66 and 67 million years ago. Stan spent the last decades at the Black Hills Institute in South Dakota, where he was studied. As a result, paleontologists have generated a large number of ...

This is how birds survived the extinction of the dinosaurs | Digital Trends Spanish

About 150 million years ago, the first birds evolved from small feathered dinosaurs, similar to what we know today as birds of prey, thus becoming another branch of the dinosaur family tree. That happened in the Jurassic. For more than eighty million years, all kinds of birds emerged, and with various characteristics. Today, birds are known as "the only dinosaurs left." In hindsight, scientists are able to classify birds into avian dinosaurs, while all other types (from stegosaurus to brontosaurus) would be non-avian dinosaurs. The meteorite that fell 66 million years ago in the Yucatan Peninsula triggered the fifth mass extinction in the history of our planet. Earth became a true hell, where forest fires abounded. In total, it is estimated that 75 percent of the sp...

Study casts doubt on everything that is known about dinosaurs | Digital Trends Spanish

The word 'dinosaur' was first uttered by British anatomist Richard Owen in 1841 at the annual meeting of the British Association for the Advancement of Science. It was up to him to make an exhibition about some reptile fossils discovered in the south of his country and Owen could not find anything better than to refer to them by joining two Greek words: 'terrible lizards'. Some time later, 160 years ago, Owen received another wonderful find at the British Museum, the first complete skeleton of a dinosaur. It was a Scelidosaurus, which had been found on the so-called Jurassic Coast of Dorset, England. The remains were around 193 million years old. Owen then published two short articles on the anatomy of the dinosaur, but many details were left unrecorded, the agency not...

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...
