在俄羅斯西伯利亞地區發現的一組最新的恐龍化石表明恐龍羽化現象可能比原來科學家們想像中更早而且更普遍。這項研究已在《科學》雜誌中發表。 請聽 BBC 記者 Pallab Ghosh 發回的報道。

The creature was about a metre long with a short snout, long hind legs, short arms and five strong fingers. Until now, fossilised evidence of feathery dinosaurs has come from China, and from a meat-eating group called theropods.

The latest discovery – in Russia – is from a completely separate group of plant-eating dinosaurs called ornithischians.

The new find takes the origin of feathers millions of years further back in time than had previously been thought. And, according to the researchers, completely changed ideas about how dinosaurs evolved.

Instead of thinking of them as dry, scary scaly creatures, a lot of species, especially when very young, actually had a fluffy, downy covering like feathers on a chick, they say. And did so when dinosaurs first emerged.
