Researchers in Germany have unearthed a new species of flying dinosaur that flapped its wings like a raven and could hold vital clues as to how modern-day birds evolved from their reptilian ancestors.

For more than a century and a half since its discovery in 1861, Archaeopteryx -- a small feathered dinosaur around the size of a crow that lived in marshland around 150 million years ago -- was widely considered to be the oldest flying bird.

Palaeontologists from Ludwig-Maximilians University (LMU) in Munich and the University of Fribourg examined rock formations in the German region of Bavaria, home to nearly all known Archaeopteryx specimens.

Game of Thrones: The Story Behind the Hound's "Little Bird" Nickname For Sansa

Game of Thrones: The Story Behind the Hound's The history shared between Sansa Stark and Sandor Clegane, aka the Hound, is a complicated one that stretches back years on Game of Thrones. The pair hadn't met for several seasons, until they finally share a scene again in the fourth episode of the final season, "The Last of the Starks." In referencing Sansa's past, the Hound calls her "little bird." It's a nickname that Sansa has heard before, from more than one place. In her early days as Joffrey's fiancée in King's Landing, Sansa is often referred to with different kinds of bird imagery.

They came across a petrified wing, which the team initially assumed to be the same species. They soon found several differences, however.

"There are similarities, but after detailed comparisons with Archaeopteryx and other, geologically younger birds, its fossil remains suggested that we were dealing with a somewhat more derived bird," said lead study author Oliver Rauhut from LMU's Department of Earth and Environmental Sciences.

The study, published in the journal eLife Sciences, said Alcmonavis poeschli was "the most bird-like bird discovered from the Jurassic".

As well as being significantly larger than Archaeopteryx, the new specimen had more notches in its wing bones that pointed to muscles which would have allowed it to actively flap its wings.

Significantly, this "flapping" trait found in Alcmonavis poeschli is present in more recent birds, but not in Archaeopteryx.

"This suggests that the diversity of birds in the late Jurassic era was greater than previously thought," Rauhut said.

The discovery is likely to fuel debate among dinosaur experts over whether birds and dinosaurs developed the ability to flap their wings from earlier gliding species.

"Its adaptation shows that the evolution of flight must have progressed relatively quickly," said Christian Foth, from the University of Fribourg, and a co-author of the research.
