A treasure trove of fossils that it contains a dinosaur bone, bird feathers, and the existence of feathered dinosaurs over the southern polar circle has been discovered in Australia.
A team of researchers has analyzed 10 of the fossil feather was found, including tufted hair-like proto-feathers ” of the meat-eating dinosaurs, along with the soft body feathers and the wing feathers of the ancestral birds, which could be used for the flight,” according to a statement accompanying the study.
“Dinosaur skeletons, and even the fragile-looking bones of ancient birds have been found in the ancient high latitude, for. However, to date, are not directly attributable to covering the remains were discovered, in order to show that the flight feathers are used, in order to be able to survive in extreme polar habitats,” said study lead author Benjamin Kear, in a statement.

THE WORLD’S OLDEST MEAT-EATING DINOSAUR FOUND
“This is the Australian fossil feathers, therefore, are very important because they were from a small dinosaur and a bird that lives for a season and very cold, with the months of polar darkness in each and every year,” Kear added.
The fossilized feathers have been found in the Koonwarra Fish Beds, Geological Reserve, and were embedded in the muddy sediment at the bottom of a lake.
“Fossil feathers are known from Koonwarra, since the beginning of the 1960s, and became recognized as an evidence of the old birds, but have, otherwise, had very little scientific attention,” said Thomas Rich, from the Melbourne Museum, in Australia, in a statement. “Our study is the first to fully document, that is, new samples were investigated with the aid of cutting-edge technologies.”
To fossil bird expert, Professor Patricia Vickers-Rich from Monash University, and Swinburne University of Technology in Australia, said that the springs have to be “kept in every detail,” adding, “There is even a relatively small filament-like structures that could have ‘zipped’ the feather of the blades together, like the flight feathers of modern birds.”

In contrast to the feathers of modern birds, small dinosaurs had proto-feathers” are likely to be used in order to stay warm, according to experts in the field.
“Dinosaur proto-feathers would have been used for the isolation,” said one of the study co-authors, Martin Kundrát. “The discovery of the ‘proto-feathers’, at Koonwarra, therefore, suggests that a soft, down-filled jackets should be able to help a small dinosaur to keep warm in the old polar habitats.”
The study, which was published in the scientific journal Gondwana Research.
