Still Waters Posted February 10, 2022 #1 Share Posted February 10, 2022 (IP: Staff) · The fossilized remains of an immature diplodocid—a large, long-necked herbivorous sauropod dinosaur, like Brontosaurus—may provide the first evidence of a unique respiratory infection in a dinosaur, according to a study published in Scientific Reports. The findings increase our understanding of the illnesses that affected dinosaurs. The specimen, nicknamed "Dolly," was discovered in southwest Montana, U.S., and dates back to the Late Jurassic Period of the Mesozoic Era (approximately 150 million years ago). Cary Woodruff of the Great Plains Dinosaur Museum in Malta, along with his colleagues, examined three of the cervical vertebrae (the bones from the neck) from Dolly and identified never-before-seen abnormal bony protrusions that had an unusual shape and texture. These protrusions were located in an area of each bone where they would have been penetrated by air-filled sacs. These air sacs would have ultimately connected to Dolly's lungs and formed part of the dinosaur's complex respiratory system. CT imaging of the irregular protrusions revealed that they were made of abnormal bone that most likely formed in response to an infection. https://phys.org/news/2022-02-sauro-throat-evidence-indicating-dinosaur-respiratory.html Quote The first occurrence of an avian-style respiratory infection in a non-avian dinosaur https://www.nature.com/articles/s41598-022-05761-3 4 Top Link to comment Share on other sites More sharing options...
