Microscopes and spectroscopes allowed researchers to accurately capture the details of dinosaur anotomy.
"Dinosaur protoplumas could have served to offer them thermal protection. The discovery of protoplumas in Koonwarra suggests that it was the plumage of small dinosaurs that helped them conserve heat in polar habitats, "said the study's lead author, Martin Kundra, of Pavol Jozef Safarik University (Slovakia).
To better understand the conditions in which these dinosaurs had to live it is necessary to go back in time millions of years, when on the face of the Earth there was only the continent of Gondwana. The center of this land mass was located more or less in the current south pole.
At that time the weather was warmer and the ecosystems were rich in flora and fauna. The poles of this continent recorded long periods of sunlight in summer and plunged into absolute darkness during winter. Therefore, any living being had to get used in one way or another to live in extreme conditions during cold twilight.
With this discovery, scientists hope to add one more piece to the dinosaur evolution puzzle. In addition, paleontologists discovered in those fossil melanin pigments, suggesting that Gondwana dinosaurs were dark to absorb heat.
