Scientists have found a new species of dinosaur that are ‘fluffy’ in Siberian region.
The new discovery has given clear indication to palaeontologists that almost all dinosaurs may have been feathered.
150 million-year old fossils of Kulindadromeus zabaikalicus, which is a two-legged, 4.5 feet-long beaked dinosaur, suggested that the species had both feathers and scales.
“The discovery is a view changing about dinosaurs,” Lead author Pascal Godefroit, from Royal Belgian Institute of Natural Science.
According to the scientists, the evolution of feathers in dinos was as a form of insulation. As they grew older, some larger dinosaurs may have lost them.
Co-researcher Dr Maria McNamara said, “So, instead of thinking of dinosaurs as dry, scary, scaly creatures, a lot of them actually had a fluffy, downy covering like feathers on a chick.”
Before this discovery, it was believed that dinosaurs possessing feathers only existed in the middle of the Jurassic period. But the newly found discovery has suggested that many of the dinosaur species had “small, fluffy, chick-like” feathers from very early, Pallab Ghosh of BBC said.
However, some experts differ from the findings, saying the ‘feathers’ could be something different.
Dinosaur researcher Dr Paul Barretts, of Natural History Museum, said the so-called feathers could just be “very unusual scales”.
The differing views call for more in-depth analysis of the findings.
