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...

How much did the dinosaurs weigh? These methods answer it | Digital Trends Spanish

How exactly is an extinct dinosaur weighed? Although paleontologists use different methods, for obvious reasons, none involve actual weighing. But to determine which is the most appropriate formula, one study compared the different approaches. The research, published Sept. 1 in the journal Biological Reviews, involved a review of techniques for estimating the body mass of dinosaurs that have been in use for more than a century. Estimating the mass of a dinosaur like the iconic tyrannosaurus rex is not an easy thing: it is a creature that took its last breath some 66 million years ago and, for the most part, there are only traces of its bones. It is a challenge that has put the ingenuity of paleobiologists to the test. Scientific estimates of the mass of the largest l...

Dinosaur of the Tyrannosaurus Rex Family Discovered | Digital Trends Spanish

A new species of theropod dinosaur, the group that includes the tyrannosaurus rex and modern birds, was discovered by paleontologists at the University of Southampton. After analyzing four bones found in 2019, the researchers concluded that the dinosaur lived in the Cretaceous period, 115 million years ago, and could measure up to four meters long. The bones of the so-called vectaerovenator inopinatus They were discovered on Shanklin Beach on the Isle of Wight, UK, and correspond to the neck, back and tail. Darren naish The name alludes to the large air spaces in some of the bones, one of the features that helped scientists identify their theropod origins. Air sacs, also seen in modern birds, were extensions of the lung likely to help feed an efficient respiratory syst...

Historic: Cancer Discovered in Dinosaur Fossil | Digital Trends Spanish

In a landmark event, Canadian paleontologists discovered a cancer tumor in a fossil of dinosaur 76 million years old. This is highlighted in a report published this Tuesday in Lancet Oncology. It is the first time that specialists in palentology discover evidence of cancer in a prehistoric animal, he reported. Gizmodo. In 1989 researchers at the University of Alberta, Canada unearthed the fibula of a Centrosaurus Apertus, a four-legged and chubby dinosaur from the Cretaceous period. The piece was deformed, but the scientists did not pay much attention to it and believed that it was a malformation caused by a fracture. In 2017, David Evans, president of vertebrate paleontology at the Royal Ontario Museum (ROM) noted the fossil's strange features. He analyzed the skeletal...
