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...

Discovered in Egypt the fossil of a whale with four legs | Digital Trends Spanish

A group of Egyptian researchers announced the discovery of a new species of whale after the discovery of a fossil in the Western desert of Egypt. Is about Phiomycetus anubis, named after the ancient Egyptian jackal-headed god of the dead. The results of this finding were published in the scientific journal Proceedings of the Royal Society B: Biological Sciences. They indicate that this semi-aquatic predator is related to whales and could provide new clues about the evolution of cetaceans. Robert W. Boessenecker.According to the researchers, this specimen swam and walked 43 million years ago thanks to its four legs. It was a fearsome predator three meters long, capable of easily biting its prey both on land and in water. Paleontologists made this finding in the Fayoum depression in 2008...

Remains of a 100,000-year-old giant bat found | Digital Trends Spanish

If bats scare you, imagine how he must have been Desmodus draculae, an extinct species of vampire bat that inhabited Central and South America during the Pleistocene and whose size was 30 percent larger than that of its living relative, the common vampire bat (whose wingspan is 50 cm). Well, according to a study Posted by Science Alert, the jaw of a specimen of this extinct species has been discovered in a cave in Argentina. The fossil, believed to be 100,000 years old, is helping provide some clues as to why these bats went extinct, how they lived, and charting the evolutionary history and diversification of species. "They are the only family of bats in the world that arouses curiosity about the legends of Transylvania and Count Dracula," said paleontologist Mariano Magnussen from the...

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...

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...
