Scientists have discovered the first evidence of a unique respiratory infection in the fossilized remains of a dinosaur that lived nearly 150 million years ago. Researchers examined the remains of an immature diplodocid — a long-necked herbivorous sauropod dinosaur, like ‘Brontosaurus’ – dating back to the Late Jurassic Period of the Mesozoic Era. The dinosaur nicknamed ‘Dolly,’ discovered in southwest Montana, had evidence of an infection in the area of its neck vertebrae.
