Analysis of fossilized Antarctic bird's 'voice box' suggests dinosaurs couldn't sing. Which is to to say:
The discovery of the Mesozoic Era vocal organ (Nature, paywalled) -- called a syrinx -- and its apparent absence in non-avian dinosaur fossils of the same age indicates that the organ may have originated late in the evolution of birds, and that other dinosaurs may not have been able to make noises similar to the bird calls we hear today.Dinosaurs didn't quack or cluck, but may have sounded more like an ostrich (more samples).

"The tail of a 99-million year old dinosaur has been found entombed in amber, an unprecedented discovery that has blown away scientists....The amber adds to fossil evidence that many dinosaurs sported feathers rather than scales. " [more inside]
A few months ago, I went searching for the truth about that missing bone. I was not the first — plenty of others have sought the largest dinosaur that has ever lived. What I found was a quest that has driven some people toward maniacal competition, some to conspiracy theories and others to disregard scientific consensus. It drove me to a little rocky outcropping on a hill in rural Colorado known as Cope’s Nipple.—The Biggest Dinosaur In History May Never Have Existed by David Goldenberg is about Amphicoelias fragillimus, a species of sauropod dinosaurs described by famed paleontologist Edward Drinker Cope from a single, enormous bone, which later went missing. It may have been the biggest of the big, as explained by Prof. Ken Carpenter [pdf] or a fiction created by a typo [pdf], as argued by Cary Woodruff and John R. Foster.
A team of researchers, including University of Edinburgh paleontologist Stephen Brusatte and Swarthmore College Associate Professor of Statistics Steve C. Wang, cataloging 853 skeletal characteristics in 150 dinosaurs and analyzing the rate at which these characters change, and they found that "there was no grand jump between nonbirds and birds in morphospace." In other words, birds didn't suddenly come into existence, but evolved, bit by bit, or characteristic by characteristic. But when birds were finally a thing, they went crazy. "Once it came together fully, it unlocked great evolutionary potential that allowed birds to evolve at a super-charged rate."
