A team of scientists from the University of Utah and the Carnegie and Smithsonian museums of natural history have described a new species of dinosaur that looks like a mixture of a large chicken and a reptile. The discovery of this new species that has been baptized as Anzu wyliei or "chicken from hell", has been published in the magazine Plos One.
The fossil of the new dinosaur, baptized with the name of "Nanuqsaurus hoglundi" is 70 million years old and was discovered in northern Alaska, in the area of "Prince Creek Formation".
A team of Spanish paleontologists has discovered the most recent dinosaur footprints in Europe on the banks of several Pyrenean rivers. The tracks correspond to the hadrosaurid subspecies known as "duckbill", which would have lived in this place until the end of the Cretaceous, when the impact caused the mass extinction of all non-avian dinosaurs.
'Nasutoceratops titusi' is the name of the new dinosaur discovered in the Utah desert by a group of American paleontologists. It has a huge nose and antlers and the find would support the hypothesis that similar but different species evolved on the same terrain.
Until now it was thought that the strange "crouching" way of walking of some dinosaurs and modern birds was their way of maintaining balance after the tail of large reptiles progressively shortened. But a study with 3D models led by scientists at the Royal Veterinary College in London and published in the latest issue of Nature contradicts this hypothesis, claiming that the way of moving changed due to the lengthening of the legs.
A study carried out by scientists at the University of Alberta (USA) and published in the Chinese Science Bulletin magazine has revealed that dinosaurs were capable of swimming paths. They have reached this conclusion after finding, in lands that coincide with the bottom of a prehistoric river located in present-day China, marks on the tips of the fingers and the nails of the hind legs that could only have been created by these giant reptiles while they swam in its waters.
Although a century ago scientists thought that the dinosaurs of the Tyrannosaurus rex species walked upright, they discarded the hypothesis several decades ago when they found that their posture was more like that of a bird, with its tail raised and its head forward in front of its two muscular hind legs. However, an outdated image of this upright Jurassic dinosaur remains in the popular imagination, as shown by a study carried out by paleontologists from Cornell University in New York (USA) echoed by the Associated Press.
