They find the fossil of a huge Cambrian animal | Digital Trends Spanish

Palaeontologists from the Royal Ontario Museum have discovered lthe remains of a huge new species belonging to a group of extinct animals corresponding to the Cambrian period. The 500-million-year-old fossil has been located in Kootenay National Park, in the Canadian Rockies. The species has been named as Titanokorys gainesi and according to experts. It stands out for its disproportionate size in comparison with the rest of contemporary species. Its length was 0.5 meters, so the Titanokorys was quite a giant if we consider that most of the animals that lived in the sea at that time were barely the size of a little finger. "The size of this animal is absolutely mind-boggling, it is one of the largest Cambrian animals ever found," says Jean-Bernard Caron of the Royal Ontario Museum. T...

They find a fossil of the pellagornithid, the largest bird in history | Digital Trends Spanish

A set of fossils found four decades ago in Antarctica belongs to the largest flying bird in history, a study revealed. Known as pelagornithids, this group of birds could grow up to 21 feet (6 meters), according to researchers at the University of California at Berkley. The dimensions are compared to the 11.5 feet (3.5 meters) that the wandering albatross can measure, the largest bird today. The ages of the fossils, which range from 65 million years to 2.5 million years, suggest that the pelagornithids arose after the great extinction of the dinosaurs. According to the researchers, these birds traveled the Earth's oceans for at least 60 million years. "Our discovery of fossils, with an estimated wingspan of 5 to 6 meters, almost 20 feet, shows that birds evolved to a truly gigantic ...

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...

Thousands of Mammoth Bones Found Under a Mexican Airport | Digital Trends Spanish

The future Mexico City airport, which is being built in the town of Santa Lucía, has not only brought headaches to President Andrés Manuel López Obrador, it is also a rich site of prehistoric animal remains. This Monday, August 31, the agency Efe reported that skeletons of mammoths, camels, horses, bison and possibly saber-toothed tigers have been found at the site, making it the most important paleontological discovery in Latin America, due to the number and concentration of individuals. Only in the case of mammoths there is already an inventory of 8,000 bones. In fact, there is an almost complete skeleton of an adult mammoth. "We never dream of a project of this magnitude, it is a challenge and it is a happiness because these opportunities are seldom had," Rubén Manz...

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...

The Last Supper: Fossil Found in the Stomach of an Ichthyosaur | Digital Trends Spanish

A major surprise found a group of paleontologists excavating a quarry in southwest China after discovering the almost complete skeleton of a giant marine reptile, similar to a dolphin, known as an ichthyosaur: another fossil in its stomach. The second skeleton belonged to a four-meter-long lizard-like aquatic reptile, known as a thalatosaurus, and is one of the longest fossils ever found in the stomach of a prehistoric marine reptile. While researchers cannot say with certainty whether the thalatosaurus was captured or predated, his work may be the oldest direct evidence that marine reptiles of the period TriassicLike ichthyosaurs, which were previously thought to feed on cephalopods, they were mega-predators. "If you look at all the similar marine reptiles that lived i...
