Dinosaurs may have SANG like birds rather than roaring like monsters
Researchers discover remains of ancient songbird and hail it as 'important step in figuring out what dinosaurs sounded like'

The discovery of ancient "songbird" remains has raised the possibility that dinosaurs may have been able to SING.
All birds living today are descended from a particular family of dinosaurs that developed feathers and the ability to fly.
Now dino experts have found the earliest ever fossilised "syrinx", which is an arrangement of vibrating cartilage rings at the base of the windpipe.
However, the song of the proto-bird which possessed this syrinx was a long way from the lilting notes of a song thrush or blackbird.
Scientists believe the extinct duck and goose relative that possessed the organ was only capable of making honking noises.
The bird, Vegavis iaai, lived during the Cretaceous era.
Although its 66 million-year-old fossil bones were unearthed from Vega Island in Antarctica in 1992, it was not until three years ago that experts spotted the syrinx.
Dr Julia Clarke, from the University of Texas at Austin, US, who led a study of the fossil syrinx published in the journal Nature, said: "This finding helps explain why no such organ has been preserved in a non-bird dinosaur or crocodile relative.
"This is another important step to figuring out what dinosaurs sounded like as well as giving us insight into the evolution of birds."

Unlike the human voice box, or larynx, the syrinx does not employ vocal cords but instead consists of stiff, cartilage rings that vibrate to produce sound.
Cartilage does not mineralise as well as bone, making it rare in the fossil record.
So far the Vegavis syrinx remains the only one known to scientists from the age of the dinosaurs.
The researchers are now comparing the organ with its equivalent in living birds in search of clues about how the earliest birds may have sounded.
"The origin of birds is about so much more than the evolution of flight and feathers," Dr Clarke said.
She led a previous study reported earlier this year showing that some dinosaurs would probably have made closed-mouth noises similar to ostrich "booms", that do not require a syrinx.
