![]() ![]() Even a single bird species makes a wide range of noises, and there are other organs at play, from the mouth and nose to possibly a syrinx, he said. But it is too soon to understand what specific sounds dinosaurs might have made, he cautioned. “There’s still possibilities that they made chirping and cooing” noises, Dr. ![]() That’s probably not true, but “they might have had a broader range of sounds than we might give ankylosaurs credit for otherwise,” she said. People might assume that sounding birdlike would mean these dinosaurs were tweeting like meadowlarks, Dr. ![]() That might have allowed ankylosaurs to vocalize in a way similar to birds, the researchers reported recently in the journal Communications Biology. The other larynx part, a relatively long pair of bones, could have permitted the windpipe to change shape to modify sounds, he added. One part that forms the base of the ankylosaur’s larynx was very large compared to those of other animals, suggesting that this dinosaur could open its airway wide to make loud calls that could be heard far away, Dr. They also have another organ, located near their mouths, for changing up those sounds, allowing some birds to create elaborate songs. Birds possess a different organ, called the syrinx, that sits close to their lungs to produce sound. In extinct and living crocodile relatives, the larynx produces sound. And then birds evolved these additional ways of producing sounds where they can modify the sounds coming out of their throat in a more nuanced way.”īirds and reptiles have very different ways of producing sounds using the organs that surround their windpipes and lungs. “That’s the base anatomy they’d be working with. “Assuming that dinosaurs make some crocodile-like sounds is pretty safe,” she said. “They kind of bracket the range of sounds we might expect,” said Victoria Arbour, a paleontologist at the Royal BC Museum in Victoria, Canada, who was not involved in the new study.Ĭrocodiles’ vocal repertoire includes deep rumbles and hisses. Hammering Away: A study shows that woodpeckers do not absorb shocks during pecking and they likely aren’t being concussed either.Instead, the most distinctive birds are likely to vanish first. ![]() An Uneven Crisis: The risk of extinction, a study suggests, is not randomly or equally spread across the avian family.And they do it without stopping to eat, drink or rest. An Epic Flight: In search of an endless summer, bar-tailed godwits fly 7,000 miles each year - from Alaska to New Zealand.What is it about owls that’s so beguiling to humans? Why We Love Flaco : New Yorkers have followed the escaped owl’s story with anxiety and hope.(The larynx in some animals is located near the upper part of the windpipe and contains the vocal cords.) Junki Yoshida, a paleontologist at the Fukushima Museum in Japan, said the find was surprising because the body parts involved in vocalization, including the larynx, which is often made of cartilage but can be bony in some animals, were not considered to be good candidates for preservation as fossils. This squat, spiky dinosaur (Pinacosaurus grangeri) was unearthed in 2005 in Mongolia. It comes from an ankylosaur, a group of armored plant-eaters that were not close relatives of birds. In the next generation of dinosaur-based blockbuster films, some of the star creatures could perhaps sound more like a bird and a little less like a roaring lion.Īt least that’s a possibility raised from new research published this month, although very little is really understood about dinosaur vocals.īut a research team has drawn clues about sounds the extinct creatures could have made from what might be the first known fossilized larynx of a dinosaur. ![]()
