Discovery of a new species of dinosaur with a physique close to the duck

the Natovenator polydontus was probably semi-aquatic, carnivorous, and duck-like in appearance.

The mystery is finally lifted. It all started in 2008 when a fossil of an almost entire skeleton is discovered in the Gobi desert in Mongolia. For more than ten years, scientists have wanted to know what species this animal belonged to. They know it now. According to their work published on December 1 in Communications Biology and reported by the site New Scientist, the fossil is that ofa new species of dinosaur.

Being baptized Natovenator polydontus, which means “hunter swimmer with many teeth”, would have lived in the Upper Cretaceous era, between 100 and 66 million years before our era. According to the researchers, his physique looked like a duck. Like this one, he lived between land and water.

A goose bump and needle-thin teeth

“This is the first case among dinosaurs non-avian exhibiting a streamlined rib cage like those seen in many modern semi-aquatic animals adapted to swimming”explains to the media Andrea Cau of the University of Bologna in Italy, who did not participate in the work.

The researchers also noticed that “the animal had an elegant body and a goose-like neck, something never before seen in a non-avian theropod”recount New Scientist. According to them, the new dinosaur was a swimmer and an experienced diver.

The animal’s skull included many needle-like teeth, hence its name. He probably ate Pisces and insects.

“This is a welcome discovery that helps resolve the controversial halszkaraptorin dinosaur lifestyle” a sub-family whose total knowledge still eludes scientists.
